Times and seasons change, markets diminish and regenerate; turntables
are back. Why do the "high end" products always get the limelight?
The new Gram Amp 1 with stylish livery and LED detail changes all of this,
more importantly the tweaked internals, enhanced quality capacitors and
further reduced noise floor make the new Gram Amp 1 really rock.
A fourth generation product, the Gram Amp 1 Bridge builds on the strengths of its forebears, and addresses its earlier weaknesses. Look at the reviews however, and you will see there weren't many weaknesses identifiable for its price, this is a remarkable phono pre amp and is well worth a listen.
For total immersion (in the music) an optional upgrade to the PSU1 power supply unit is available.
