Audio-GD Master-1 Fully Balanced ACSS Pure Class A Preamplifier [Expired]

no longer for sale

Amazing reviews !  This is one of the best preamplifier that I ever owned! You can look at the reviews.  Very neutral and musical.  Never aggressive and very detailed.  All the small inflections and nuances in the musical message are rendered.  I was mostly impressed with the current power it has to control the low frequencies.  They are rendered with clarity and detail... in all their nuances. No muddy sounds, only high precision.  The air and space between all the instruments is also quite outstanding.
