I have owned the Lamm ML1.1 dual mono 90W amps for the last 2 months and they have been by far the best amps I have owned. My most recent were Wavelength SET amps (Rest of my system is Wadia 861, Wilson Watt 7, Shunyata Hydra8/Python, Harmonic Tech cables). I also went back and forth between SS and tube amps. I have always wanted to go with solid state due to less maint/worry over tubes, but have come back to tubes as the best sound. In the past I have owned some of the better if not best solid state amps from Ayre, Rowland and Krell and also had CJ MV50s a while back. My current Lamm amps have been a revelation in terms of detail retreival without the stidency and more etched/sterile sound of SS amps. microdynamics and transparency/ability to present a clear view into the music. As good as the SS amps have gotten, heard most recently Spectral Mono amps, which are argueably the best or near best SS amp, the best tube amps offer a sound much closer the sound of live music played. Not sure if 90 watts is enough for your system but if you can swing the cost of the Lamm amps, they may be the "last" amp purchase.
