• PIER AUDIO SERIES MS-680SE HYBRID AMPLIFIER •
|
Creation of a very powerful hybrid vacuum tube / solid state amplifier equipped with a large 750VA power transformer coiled with high quality copper.
• 4 pairs of Toshiba bipolar power transistors (no MOSFET at Pier Audio) • Supply capacitors Rubycon/Nichicon/Elna depending on stock. • Polypropylene electrical capacitors from Wilma and SCR (France) • Full by-pass (the sound goes through the pre-amp part and its 4 tubes, a “Pier Audio” feature dedicated to Audio Video amps on their pre-out output to finally diligently power the 2 main speakers of an AV system with a higher sensitivity level of 500 mV instead of 240 mV of the other RCA inputs and compensate for the chronic anaemia of this type of consumer AV device for listening in pure audio on 2 stereo channels. • Motorized ALPS potentiometer to better temper its natural dynamics • The chip of the Dac part on USB is a Texas PCM 2706, no direct flac reading, but only wave and wma 16 bit 44.1khz, to be considered as a mini add-on Dac to discover the files but will never be able to match a real quality external Dac. • A deep, vivid sound, and very "tube" despite its 8 output transistors, the other technology with obvious quality that should not be ignored: sound transparency/speed/power/tone. This hybrid realization is there to prove it once again. This hybrid production is there to prove it once again.
