I'm a monoblock fan and have two sets, one tube based and one solid state. My tube monos are the big Conrad Johnson LP275M's each using eight ST120 power tubes and three 6922 signal tubes. My SS monos are the big (and very heavy) Bryston 28BSST's. I have Wilson Alexia speakers in a relatively large, dedicated listening room. I use the CJ amps the most and they have a permanent place on my equipment center. The Brystons are kept on heavy duty furniture dollies so that I can wheel them over in front and swap them into and out of the system at will. Bryston gear is built to last and sounds really good. Their 4BSST and above amps will power just about any speaker made, and do so with authority.
