I read this posting with interest. I had recommended Rogue to someone about twenty years ago. It blew a tube shortly after my friend received his… it took out the channel. The owner argued that it was not covered by warranty… the tube did it, although it was only a month old. I was humiliated. So, I do not normally comment on Rouge. But this chain is not much of an endorsement.
I would look at an Used Audio Research preamp. They are world class, and if you are spending $5K, you should get something really outstanding. Built like a tank, ready for a lifetime of outstanding performance. Look at ARC Referebce 3 or higher.
