Bob Carver 180 Mono-blocks perform superbly

Man! You're right. I having a total recall. I don't use active preamps, so it slipped my mind.

This becomes an interesting read towards the bottom.

Ah yes, I remember this story of Bob and Stu Hegeman. The best designers of the glory tube years would never consider designing a SET amp, including Bob. It was PP class AB amps all the way, and to my ears they are more neutral than any SET amp I've heard. Bob is an entertaining story teller. Thanks for the link Vic.

Bob Carver tube amp owners should unite and ask for stepped volume control and better output coupling caps as upgrade options. They're easy upgrades that significantly improves the sound.

Hi Dracule. Despite your wholehearted recommendations of upgrading the vol control and output caps I have decided to leave the amps as is mainly for warranty issues. I am still waiting for my upgraded KT88s and a few more input tubes to arrive. Fun days ahead!

I do have a question for 180 users though. If using a CD player with volume control directly connected to the Bobs, who sets the Bobs vol knobs to max and adjusts volume via the CD player? Previously I had the CD player output maxed out and used the Bobs to adjust volume to each channel. But lately I have been having problems with imaging with this approach. Sound quality wise I can't seem to tell a difference. Cheers.
