" The Monaco Turntable is truly a 21st century design which establishes a new state-of-the-art in design and engineering. "
Sunday 15 June 2008

The Monaco Turntable
The Monaco Turntable raises the bar when it comes to speed accuracy and lack of rumble. It is the first analog device of its kind. With many features simply not possible several years ago.
Features include:
DSP Signal Processing / Active Feedback Loop Technology:
Our speed control features a CPU utilizing a Digital Signal Processor that interrogates and maintains the speed of the platter thousands of times each revolution and thereby ensures frequency accuracy and distortion free playback that is simply not possible with conventional types of drive systems. A highly accurate test procedure has demonstrated the speed error to be an extremely low .002% peak error! Speed accuracy equals frequency accuracy, which means there is virtually no distortion on playback.
“ So direct-drive might seem like the star, but even a star needs a supporting cast, and here that cast are also stellar - as is the resultant performance. ” Review: Roy Gregory, Hi>Fi+ Issue 57
Magnesium Platter, DC Motor, Phosphor Bronze Bearing and Internal Flywheel:
The magnesium platter and phosphor bronze flywheel are supported in a fully immersed bearing system that provides a pressurized film of oil that suspends and damps in the horizontal plane. Rotation is supplied by a low voltage brushless DC motor custom made to our specifications.
Carbon Fiber Plinth:
A high pressure high temperature cured composite structure is the ultimate for a turntable plinth. This material allows design of hollow organic shapes with compound curves and varying thicknesses to give a carbon fiber structure superior to any other for rigidity and damping with unparalleled elegance in form. When you add internal polymer damping the performance of this plinth is unrivaled in its vibration management and rigidity.
No mechanical Contact Oil Suspension Bearing and DC Drive System:
Our innovative and unique bearing and drive system achieves ultra low noise levels. There is no mechanical contact in the horizontal plane as the platter is suspended in a fully immersed pressurized film of oil. Power is supplied through the magnetic field produced by the brushless DC motor maintaining the no mechanical contact principle. No seals, no belts, no gears, no contact.
Separate Isolated Thrust Bearing:
The vertical position of the platter is fixed by a uniquely designed rigid single point contact thrust bearing. This bearing is separate from the Oil Suspension platter bearing. This state of the art ceramic bearing is fully immersed in oil.
“ In my opinion, our Monaco is without equal the first ever commercially available turntable capable of keeping such accurate speed … it is the finest example of serious turntable engineering on the market today… the first and only ever table to allow such an enormous amount of detail to be extracted from vinyl un-coloured…. ” Steve Eleftheriadis, Reference Audio Visual Pty. Ltd
WHITE PAPER
The revolutionary GPA Monaco Turntable is the first and only turntable design taking advantage of 21st Century technology for speed control. It does this by properly utilizing a Digital Signal Processing (DSP) controller coupled with an active feedback loop to control the actual motion of the platter itself. It is simple, elegant and the true measure of design and engineering excellence. It is painstakingly manufactured and carefully handmade entirely in the USA. It is repeatable to near 100% consistency by each and every owner anywhere. It is simplicity itself to set up and is devoid of any shift in settings over time. Truly a “set and forget” design. In this paper we will present the actual physical test results showing the behavior and performance of our design.
“ The musical performance is an all-time high — astounding. I’ve experienced some of the world’s best, but I’ve never heard a turntable even close to yours. It’s a different league of source. In a single word, neutrality; it adds or subtracts nothing from the music…” Now, I’m afraid that you’ll have to find a new dealer. I’m closing down at 6PM and retiring from work. I have 6,000 LPs to play. You have my deep respect. The Monaco turntable wasn’t a few weeks’ design work. And to achieve this at a relatively affordable price with relatively simple set-up, makes the achievement even more worthwhile. I just hope I can do my job, which is to find and attract people who are interested in it. ”
