Rega is extremely pleased to announce the launch of the much awaited RP8 turntable. A turntable which takes Rega’s design philosophy further than ever before. A radical new plinth using custom designed materials, a new tonearm bearing assembly, 24v low volt-age motor controlled by a hand tuned electronic power supply and a custom version of our Planar 9 engineered hub bearing assembly. These are just some of the features of this amazing new turntable designed to extract more music from your vinyl than ever before.
The Evolution of Revolution
Evolution is a well-proven and documented process in many areas of our lives. This applies in particular to design engineers and machines. Over the past forty years our cars have become more reliable and economical whilst we take for granted the reliability and speed of modern aircraft.
Rega is no exception to evolution. Rega’s experience and previous achievements allow us to continually develop and produce better products.
The RP8 represents probably the biggest step forward in the evolution of Rega founder Roy Gandy’s turntable design philosophies. Low mass, high-rigidity plinths combined with electronically-controlled low-vibration motors, high flywheel effect platters and lower mass higher stability tonearms.
The RP8 is the first of our new “skeletal” design turntables offering groundbreaking levels of performance and amazing value for money.
The RP8 will also be available with its perfect partner, the Apheta moving coil cartridge, factory fitted as a package option.
TTPSU power supply
The compact TT-PSU uses a high stability, crystal locked, low distortion sine wave generator. This, along with an efficient drive amplifier fed from a stabilised DC power supply, generates a 24V AC balanced signal of less than 0.05% distortion, which is completely un-affected by any changes in the mains/line voltage and conditions. This then drives the improved Rega anti-vibration circuit built into the RP8 motor PCB.
The RB808 tonearm is packed with new features pushing the boundaries of tonearm design. As with all Rega tonearms each one is meticulously hand built by a team of highly skilled technicians. The RB808 has improved bearings and a tightened spindle fit tolerance over previous models (each bearing is individually selected to find the perfect match for the chosen spindle). This is a proven method of increasing the amount of detail retrieved from the record surface.
A brand-new, low-mass precision engineered vertical bearing assembly has been manufac-tured to further compliment the inherent design philosophy of the RP8 turntable. The RB808 uses the latest Rega arm tube. Completely redesigned to redistribute mass, further reduce stresses and resonances. This advanced design tube increases the stiffness and rigidity of the overall assembly using CAD design to blend the multiple varying tapers. Externally we have fitted a bespoke Rega designed low capacitance phono cable. Which uses an advanced phono plug assembly. This has only two parts to minimise joints and incorporates a twist and clamp design locking the plug to the terminal. The design increases connectivity and keep the signal path as clean as possible.
Magnesium and Phenolic - Dual bracing
A super lightweight plinth combined with a double brace mounted specifically where the increased rigidity is required (between the tonearm mounting and the main hub bearing) forms a structurally sound “stressed beam” assembly. This design prevents energy absorption and unwanted resonances which will add un-natural distortions to the music. The RP8 takes our double brace technology to the next level. Not content with an unprecedented stiffness to mass ratio, Rega have obsessively reduced any resonant properties by using two different materials for the new stressed beam. The top layer is magnesium and the bottom layer is pheno-lic (two of the lightest and stiffest materials available). Incorporating two different materials into the brace structure lowers their ability to pick up unwanted airborne vibrations. Simply put, different materials have different natural resonances. By using two different materials together they decrease the natural frequency of each other by self damping.
Super flywheel effect triple layer glass platter
The new RP8 three piece laminated glass platter is the result of a collaboration with a small, emerging, young British glass engineering company. As a general rule the only part of a turntable that requires extra mass is the turntable platter in order to achieve constant rotational speed. However a heavier platter creates more problems for the main bearing design so again an ideal compromise creates the best solution. Practically this means keeping as much of the mass to the outside rim of the glass platter to create more flywheel effect but keeping the inside of the platter as light as possible without sacrificing stiffness. The RP6 was the first Rega turntable to use a precision engineered glass ring laminated to the outside using modern CNC techniques to ensure concentricity. The RP8 takes it one step further by laminating three rings together to produce the RP8 super flywheel effect glass platter - an engineering triumph !
Skeletal plinth design with polyolefin foam core
Controversially, Rega has always researched methods of producing light but stiff and rigid plinths. The technology is simple: unwanted noise at microscopic levels is developed by the turntable motor and main bearing. The plinth can also pick up airborne vibration from the music. From the beginning in the 1970’s Rega pioneered the use of a stressed skin structure for the plinth. This uses two layers of phenolic resin with a lightweight particle or fibre board sandwiched between the skins. This technique has been used in many applications where stiff, light structures are needed such as an aircraft wing or a Formula 1 chassis. The current increase in interest in turntables has allowed Rega to research and develop higher technology structures for the customer who is happy pay a little more for higher sound quality. The all new RP8 turntable utilises a unique new stressed skin structure produced from thin phenolic skins sandwiching a featherweight nitrogen expanded, closed cell, polyolefin foam core. This material has been developed exclusively for Rega over a three year period. The RP8 plinth is 7 times lighter than the weight of the original Planar 3 plinth. Rega has added even more stiffness in the crucial area between the arm and the main bearing.
De-coupled outer frame and dust cover
A common problem for many skeletal design turntables is the inability to incorporate an effective dust cover into the design. We have constructed an outer frame that minimises contact between the inner and outer plinth. The only points of contact are three location devices on the feet which centralises the inner and outer plinths perfectly. This makes set-up extremely easy and allows the use of a dust cover. The RP8 can be used without the outer frame if so desired.
Turntable design & mythology
Today, there are many approaches to Hi-Fi design which follow established and informed engineering or electronic principles. Amplifier and loudspeaker design has been well documented over the years with excellent technical publications. These subjects have been based on tried and tested acoustic criteria and many computer software programs now exist that enable a near amateur to design a passable working loudspeaker based on known acoustic and mathematical parameters.
Enter turntable design: When it comes to turntable design we are limited to a few poorly-informed articles describing only very limited aspects of design. This is a subject full of mythology. Designers propose theories that counter the basic laws of physics, use terminology that doesn’t actually exist in the engineering world, build products that are more like beautiful sculptures than acoustic reproduction machines and sell items costing tens of thousands of pounds that hardly function as intended and often fail to work at all.
For instance, a very common myth is “the heavier the better” concept. Turntable bases weighing tens of kilograms are not uncommon. The reality is that the base actually needs to be as light as possible to prevent unwanted bearing and motor noise being transferred to the turntable or record. Platters also fall under a similar myth with many platter designs becoming so heavy that it is impossible to design a correctly functioning bearing (and some so light that anyone can hear the speed inconsistency). The turntable platter itself needs to be of enough weight to spin at a constant speed within the confines of the chosen bearing and motor drive system.
Many amateur designers in any field choose one component in a design and try to achieve an extreme in size, weight and quality. They believe that by taking one theory to its extreme the design will become “perfect”. The reality of all engineering, design (and life) is that perfection is not possible. Based on this reality, Rega’s goal has always been to optimise a mixture of numerous “correct compromises” thus bringing the designer nearer to the unachievable goal of perfection.
24V Low noise motor
The motor is a high specification, 24V twin phase synchronous unit which has the anti vibration circuit hand tuned to each motor and is controlled by Rega's unique and innovative TTPSU power supply. The motor drives the CNC machined pulley and sub platter/hub-bearing assembly via the belt drive.
PURETONE AUDIO will be carrying the new Rega RP8 turntable - expected arrival time stateside is early December 2012. Contact us (603) 865-5471 or via email: karl(at)puretoneaudio(dot)com for order details and pricing information.

It's been a while since Puretone Audio updated the news page...that's because we have been B-U-S-Y. Lots of new stuff coming in, lots of exciting things happening in the industry and new product hitting the shelves. In terms of mailorder - things are speeding forward rapidly. the Discogs Marketplace continues to be our main outlet for vinyl, and the worldwide thirst for records continues unabated. Brazil, Australia and the Russian Federation have been two of our biggest outlets for growth, and almost every trip to the post office includes parcels leaving for far off places. We also just received our first three 200G titles from Acoustic Sounds' new state of the art Quality Record Pressings plant; Cat Stevens Tea For the Tillerman, and Texas blues great Freddie King's Texas Cannonball and Getting Ready. <>
"These (two new LPs from Reference Recordings) and Analog Production's remastering of Tea for the Tillerman were both pressed at Quality Record Pressings, the superb Salina, Kansas, facility, and they are the best and the quietest LPs I've heard of recordings made during the LP era. In a sense, the silences of QRP's pressings, their lack of those hard-to-define anomalies of stylus-in-groove sonics, are comparable to the kind of quietness inherent in a magnetic-drive turntable...QRP has put its best feet forward. 'Spectacular' in this case means a freedom from defects (snaps, crackles, and pops) and an absence of groove noise and what I would call vinyl 'rumble,' hard to define except by contrast with normal pressings." - Harry Pearson, The Absolute Sound, January 2012 (or Issue 219) "...All you really need to know is that in every way this first effort from 'QRP' is of the highest quality...gatefold packaging which looks just like the original, only better. As far as the sound goes it is equally brilliant...And wow listening to this impeccably pressed on 200g vinyl reissue. The attack of the pick on the guitar strings is astonishingly clean and detailed. Depth is pronounced and because of both the blackness of the backdrop and the precision of both the state-of-the-art plating and the technological breakthroughs achieved in the retro-fitted presses, the resolution of low-level detail reveals a host of details that are either buried or glossed over on the other versions I've heard and own." - Jack Roberts, Dagogo, October 2011 "...Like the glossy gatefold covers used in their deluxe Impulse 45 RPM series, the cover reproduction here is absolutely top-notch...The vinyl itself arrived perfectly clean and flat, and played with nary a pop or tic throughout...The pressing is of extremely high quality." - My Vinyl Review, August 29, 2011
Released in 1972 as the second of Freddie King's three releases for Shelter Records, Leon Russell's Tulsa-based label. In fact, when Russell first formed Shelter, he reportedly did so partly to play out his vision of recording one of his favorites, Freddie King. King's output on Texas Cannonball includes brilliant covers of songs by Howlin' Wolf, Lowell Fulson, Leon Russell, Bill Withers and Elmore James. Backing artists include many musicians who played with Eric Clapton in the 1970s. Clapton has stated many times over that Freddie King was among his chief influences. Supporting musicians include Leon Russell on piano, Carl Radle and Donald "Duck" Dunn on bass, Jim Gordon, Chuck Blackwell and Al Jackson on drums, Don Preston on guitar and John Gallie on organ. Recorded at Ardent Studios in Memphis in February 1972.
"...the pure analog sound and straightforward recording technique let the music speak for itself...has an immediacy that few contemporary recordings can match, and with the QRP vinyl you'll get so much closer to the sound of the analog master tape." - Steve Guttenberg, The Audiophiliac, August 28, 2011 Freddie King is easily one of the most influential blues guitarists of his or any generation. Any blues enthusiast or guitar aficionado would have him ranked high on their list of all-time greats. He was a guitar hero before there was "Guitar Hero". Getting Ready... was King's first of three releases for Shelter Records, Leon Russell's Tulsa-based label. In fact, when Russell first formed Shelter, he reportedly did so partly to play out his vision of recording one of his favorites, Freddie King. Recorded in October 1970 at the TER-MAR Chess Studios in Chicago and released in 1971, Getting Ready... is proof positive that King was the man and that Shelter Records was one cool label. The record includes a cover of Jimmy Rogers' classic "Walking By Myself" and King references Rogers also in the lyrics of another track on the record, "Living On The Highway". Rogers was the first artist to record for Acoustic Sounds' own APO Records label and the first to appear in concert at Acoustic Sounds' Blue Heaven Studios. More APO and Blue Heaven tie-ins to Freddie King include Jimmie Lee Robinson, who while living was the veritable soul of APO and Blue Heaven. When King moved from Texas to Southside Chicago around 1950, he formed his first ever band, The Every Hour Blues Boys, with Robinson. The backing band for Getting Ready... includes the stud cast of Leon Russell on piano and guitars, Duck Dunn on bass, Don Preston on guitar, Jon Gallie on organ, Chuck Blackwell on drums and Charles Myers on drums.Also, Acoustic Sounds' Quality Record Pressings plant is now pressing Sundazed Records vinyl, which has great titles from Bob Dylan, Simon & Garfunkel and my personal favorite, Iggy & the Stooges' Raw Power. In the past Sundazed has been plagued by inconsistent pressing quality, as some records sound great and others were noisy. To find our latest and greatest vinyl listings and keep track of what has come in over the previous week, check out our PhoenixRex Discogs store.

On-TopAudio.fr recently posted spy pics of two new Rega reference-series items from the Paris High Fidelity audio show. First up was the RS10 speaker, which is filling the void at the top of the Rega product line left by the discontinuation of the R9 speakers in 2009. Malheureusement, my French isn't as sharp as it once was, but here is a rough translation of the article's findings:
The RS10 is a high-end floorstanding speaker, at a price that is still very reasonable. It seems to be, according to preliminary information we have gleaned, a three-way or four-way model loudspeaker. The cabinet is relatively deep and narrow. At the top of the facade of a polished-brushed metal baffle is installed a funny medium diaphragm transducer plane which should be about 10 cm in diameter, and overlooking an impregnated textile dome 19 mm in diameter. On the side are three openings, masked by a countersunk black cloth cover. According to the explanations given to us by officials of the company that distributes GT Audio Rega in France, two major speakers (13 and 21 cm in diameter) and an outlet vent. The first speaker works in close support while the latter would benefit from an acoustic line leading through the vent located next door. In addition, two speakers would work in series. Everybody (woofer speakers but also vent) with a different resonaant frequency, this would have a more linear response in the lower register.The French page also gave a rave on the sound quality: "It was one of the best surprises of the 2011 session of the High Fidelity Lounge." Also spied in the equipment rack below the ISIS model CD player and OSIRIS power amplifier was a new version of the IOS preamplifier. So conventional logic would seem to follow Rega will round out the reference components series with a new top line turntable, perhaps the long-rumored, carbon and x-braced P10? Hmmm....no word on pricing or availability yet. The full, untranslated article is here...

Our good friends at Analogue Productions have pulled the coup of the century (thus far) with the announcement of a forthcoming SACD pressing of the Pink Floyd classic Wish You Were Here, scheduled for release in November. And of course, like the rest of the APO SACD catalog, we WILL have it here at Puretone Audio!
Wish You Were Here is a multitrack masterpiece. Now, to have it mixed for 5.1 surround sound from the original analog master tapes by Pink Floyd's Producer/Engineer James Guthrie is, well, pretty damn exciting.
Is this the biggest SACD reissue in the history of the format? Time will tell, but don't bet against it.
Wish You Were Here(?) Now you can be. Total lifelike recreation of a chart-topping, pioneering, way-ahead-of-its-time blockbuster.
You talk about a title made for multichannel SACD! It's as if they knew 35 years ago that this format would be available. Finally, technology caught up with Pink Floyd. And oh how lucky we all are to still be around to hear this legendary studio recording in its full potential.
Pink Floyd chose Acoustic Sounds and Analogue Productions to handle the exclusive production and distribution of this monumental SACD and we are honored and thrilled to be a part of EMI's huge Why Pink Floyd...? campaign that includes remastered CDs, Blue-rays, DVDs, LPs, memorabilia box sets and this, the first-ever multichannel presentation of Wish You Were Here.
On its release in 1975 Wish You Were Here topped the album charts in both the UK and the U.S. Reflecting the band's thoughts of the time on the music business and exploring themes of absence, Wish You Were Here contains the classic cut "Shine On You Crazy Diamond," a tribute to founding band member Syd Barrett.
In fact, Barrett, who'd long been absent from the lives of Pink Floyd's band members, stopped by the Wish You Were Here recording sessions at London's Abbey Road Studios unannounced. The reunion - with Barrett reportedly appearing in poor mental condition - is said to have been an emotionally stirring event for the band, and apparently that encounter would be the last any of the band members were ever to see of Barrett, who died in 2006.
As they did with their previous release, Dark Side of the Moon, Pink Floyd made great use of studio effects for this, their ninth album overall. The record's winding soundscapes are perfect for the canvas of multichannel SACD. Spacious and airy, the record breathes like a living being.
Wish You Were Here was selected by Rolling Stone as No. 209 on their list of "The 500 Greatest Albums of All Time". And that's before they heard it like this!
