Preamps-Tube

I’m using a Mapletree Audio Design line stage. 2 chassis with tube rectification. I’ve stopped looking for better.

+1 ... Me too! Agree. And one of the best features is being able to run 6SN7 or 12SN7 tubes, depending on your taste and budget.

I have mostly used tube PreAmps with my tube Amp and am very happy with tube PreAmps. Currently I have Reimyo CAT 777 as Pre on my system.  Its tube complement includes two 12AU7s for amplification, two 12BH7As as tube buffers, and two 6X4WAs as tube rectifiers. I think they are all GEC NOS tubes as originally installed by the company. I am very happy with it and have stopped looking further . 

Allnic L-3000-hard to find used but a great tube pre.

The tube pre and ss power is a pretty good way to go.  I have a Pass Labs x150 mated with an Ayon Audio pre and I am very happy with the combination.
