Seen and listened to maintenance test. This box of matches s call'd a preamp and yes but all the hardware QUAD is done for music in the best possible conditions. This small cache is not surprising that a circuit simplicity and efficiency. it works in class A for the topology of the circuit. the modular plug-in cards by small vertical allows easy maintenance. The phono stage curiously named "DISC" is a gem of ingenuity in fact a card located al rear of the preamp can be dismantled and depending on the side of the card on which are mounted a few passive components we choose the characteristic of the cell phonolectrice! The power failed when it seems to components it amounts to half a zener diode bridge a few resistors and capacitors filtrage.En some modest sum if you understand everything is small in very small amounts in the preamp almost ridiculous, yet I havent been able to prevent m (as in j have been several in maintenance) plug it into my "big mac to see." The result of this tiny world was called 33 grand and spectacular, it was found that own the famous quad straight wire with gain but with a slight hint of breath at high levels but without affecting the quality that "little something" delivered. Its only defect is a fault c n din utlise fact sheets including a very original to the amp as well as a "cute English cord" specifically designed for him. Attention also has the strength to push the switches are just clicking. Note, however, because of the maximum originality of the mounting assembly very
treated and especially the sound. c was sort of the mini systems of rolls before the hour. NOTHING to do with plastic toys of Chinese origin type Christmas tree that invade the market and pushing the stereo to the rank of relic as the TSF.

UTILIZATION

No need for manual mode or schema for maintenance of c is hand-stitched!
simplicity is the key word in QUAD.

SOUND QUALITY

Clear all is said but with a little breath very high level as some finely crafted vinyl

OVERALL OPINION

Price unknown but unique piece ...... a recommendation!
