Tube amp for Merlin TSM.

I would recommend the new tube/ss hybrid from Blue Circle. Bobby used to use Blue Circle at the shows and I imagine the combo would be quite satisfying! Warm and detailed with a very wide soundstage. Try positioning your speakers on the diagonal!

A lot of people like the Berning ZH-270 with these speakers. Personally, I thought that the amp was too harsh in the upper midrange, though David Berning said it was more like to revealing of the attributes of digital sources. Nevertheless, there are many who would say this is a magic combination. If you were really lucky, you might find one used for $2500, but no less. That might make it out of reach.

Depending on how much power you need, Audiomat makes stupifying integrated tube amps for very friendly prices. There's one for sale on audiogon--the Solfege Reference (top of the line). It's integrated so pre-amps can get sold to cover costs. A hard choice to make if you can't listen to one first. I own the Arpege Reference (entry level), and I can't tell you how in love I am with the sound. I did get to audition it as well as a number of others.

Good luck

Thanks for the response. I am considering the Manley MAHI mini mono block which cost around 2.5k new, another option is the Opera mono block S400 cost much lower, any comments on the Opera?
