This $20K system is all about combining Laszlo Fabian's absolutely fabulous Qualiton Tube Electronics with Frank Fazzalari's Coherent Audio TWELVE Signature  Loudspeaker ... a carefully designed and beautifully voiced "Coaxial" incorporating  the very special 12" Radian driver with its 1.75" HF dome augmented by a wave guide...and an otherwise optional baffle-mounted Supertweeter. The TEWLVE is offered in 3 versions ... the Standard model - PRIME, and 2 further upgraded "Levels" including the PREMIUM and the all-out SIGNATURE. The version in this system includes the beryllium tweeter diaphragm, LessLoss Internal Cables, and the Mundorf SGO capacitor. It is available as either a Super-Monitor or as a Floorstander.


Then, we incorporated one of the most lyrical Music Servers available - the INNUOS Zen MK3. Not only is this ROON / UPNP server incredibly easy to set-up and use, it is blissfully musical, throwing a huge and super-quiet soundstage and all the detail retrieval one can possibly expect.... The INNUOS servers are truly exceptional front ends. We incorporate these into almost all of our systems.

This system's sound character being what is -- notably, the result of Qualiton's highly articulate and extended tube sound driving a large concentric high sensitivity driver, presenting a non-complex X-over load -- led us to select a DAC of the NOS type, Daniel Frauchiger's MERASON DAC-1 ... an object of zen-like beauty, of extreme attention to component design, and a diva-esque and beguiling performer, to say the least.

I really need to come back to the tube electronics ... and Qualiton's latest creation - the QUALITON X200. This "thing" is a chameleon ... a Tube version of the Swiss Army Knife ... except that is genuinely High-End in every way. The X200 can be used as a separate preamplifier, as an integrated power amplifier, as a stand-alone power amplifier with direct inputs, or as a headphone amplifier, but other configurations are possible.


The low noise analog front-end is built around a wideband and transparent circuit and features a phono preamp with enhanced precision too. Line level and subwoofer outputs are an absolute necessity in this category, and these ports are included on the back. Audio Hungary added a real specialty too: a built-in, studio grade Parallel Equalizer. This kind of tools is primarily used as a master channel effect in recording studios, to bring fresh air into the mix, as a finishing touch. We've found that this effect can also be a huge help at home as well, as it can breathe new life into certain, not so vivid records.

The balanced power amp is based on KT120 (optionally KT150, KT90, or the even the new KT170) beam tetrodes and our latest, fully symmetrical output transformer design. Due to the symmetrical circuitry, we were able to further reduce the output noise of the output stage. In addition, our new BIAS section on the front panel makes it really easy to check and fine-tune the bias levels of the output tubes. ... and all of this for $6,500 ... Thank you Laszlo !

I'll tell you this much, this amplifier makes almost any speaker sing, as the Coherent Audio TWELVE well knows :=))

This system is suitable for rooms from a minimum size of 15ft x 20 ft, and up to about 20ft x 30ft.
