Over the last 18 months I bought two Cherry Plus amps for the main and surround speakers of my stereo/HT system. Only financial circumstances have prevented me from adding a mono version for my center channel.
My impressions of the amps remain the same: clean, effortless power, from top to bottom, with all the bass control one could want and without any shrillness in the highs. I have very clean speakers, Merlin VSMs for the main and Merlin TSMs for surround. Some would say that SS amps aren't ideal for my Merlins, or at least my generation of them, but I find the Cherry/Merlin combination to bring out the best in both, if you want to hear the uncolored truth of the recording as I do.
A friend of mine has amps from another AC member company to drive Klipschorns, obviously a different flavor speaker than the Merlins. This friend believes in the law of diminishing returns in amp spending and was skeptical that the more expensive Cherries could be worth it. He brought his amps to my house and we played A/B on my Merlins. The Cherries won.
The Cherries replaced tube amps and I do not miss the fuss, power consumption or heat. In fact, until writing this, I didn't appreciate how much I didn't miss the fuss. It's wonderful to not have to deal with tubes. The Cherries have also been totally reliable and I wouldn't consider looking for replacements.
