There are some really excellent pre-amplifier designs and I have come to the conclusion this piece is often overlooked and can often be a bottleneck in the signal path. I now believe it is even more important than the amplifier. Once you narrow down what you desire, hifishark.com is your friend.
$20k(ish) tube preamps
I am considering adding a tube preamp. Anyone have experience and sonic descriptions/differences of the Luxman CL-1000, Allnic Master and Shindo Labs Vosne-Romane? Source is digital, and downstream is a Luxman M-900u. Other similar options to consider are welcome as well. Thanks!
