Not just a further development but a brand-new development on the theme of valve prestages is how the SA-31MK is presented. Two additional 6N16 valves in the output stage, redesign of the voltage control, electronic volume and input control make a clear statement which is expressed 100% in the sound.
The basis for this is based on a PHO-700 complex additional power supply, which is already used in the PHO-8. We have deliberately omitted an AC adapter and specially designed and developed a power supply. This is connected using a 9-pin DIN cable to the phono section. The voltage is again specially prepared in the power supply, so that ripple and hum of the electricity network play no role and the phono section is supplied with "clean power".
The PHO-700 presents itself in the same dimensions as the power supply. However, is due to the tube lines, combined with the known window which gives a free view to the tube. In the signal path a 12AU7 tube is used as a dual triode, which takes direct influence on the sound. High-quality components (e.g. from Nichicon or Wima) improve the parameters of noise ratio and amplification again. Of course, the PHO-700 is switchable via a switch on the rear panel for MM and MC cartridges.
The ‘Concept 20’ is a special loudspeaker which goes beyond anything that Q Acoustics has achieved before. It’s a beautifully styled product which we confidently believe provides a level of sonic performance previously thought impossible at its price point.
The Concept 20 loudspeaker cabinet incorporates ‘Gelcore Construction’TM In effect a ‘cabinet within a cabinet’, with a special resonancecancelling compound adhering between the inner and outer shells. This cabinet is both rigid and exhibits extremely low resonance. The latter is achieved through the resonance-cancelling compound absorbing the kinetic energy (movement) generated within the cabinet by the drive units, then dispersing it by converting it into heat.
Elegant, timeless, clean technology, perfection for an end stage. Here valves create the typical sound that is amplified in the power area by the transistors. In addition, the new voltage stabilisation works with a 12 AU7 valve and thereby provides a trouble-free 10W in Class A operation. The secret tip.
Description Designed with the true audiophile in mind, the MAP-800II has features and build quality typically found on much more expensive gear. An oversized toroidal transformer, balanced inputs, bi-wiring speaker terminals, bipolar output transistors and isolation spikes with protector pads, all wrapped in an ultra-rigid partitioned metal chassis with a thick solid metal faceplate. The result is an amplifier capable of driving even the most difficult loudspeakers, while reproducing all the subtle details and full dynamics of the music.
