I've been running an Audio Research Ref 6SE for a little over a year and I couldn't be happier.
What are you replacing?
$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!
