A Supratek or a Don Sachs will compete with $20,000 retail preamps.Except they will cost a lot less because you can buy them direct from the makers and avoid large wholesale and retail mark ups.The Suprateks also come with a lifetime warranty.
$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!
