Tube amp for Merlin TSM.

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?

the merlin likes gobs of power...it would not be a good match with any moderately powered tube amp regardless of quality....i would suggest a belles150 or a conrad-johnson sonographe240....they are good,high powered designs and sound a bit warmer and more euphoric than most solid state designs...if you have your heart set on tubes,i'm afraid you will never hear those beautiful merlins at their best.

Does it mean with a average 50W op tube amp won't do the job well? How about the Music Ref RM9 or will PS Audio HCA-2 fit in?

I just got my TSMs in a few weeks ago and they ARE magical with my BAT VK-60, which I've had now for the past 4 years. Highly recommended! Bob

i'm sure if you compare any of the amps i've mentioned to any 50watt amp(tube or solid state you will here a dramatic difference...the merlins are keepers,but they only perform with a bit of power to spare.
