My Mid Monos sound wonderful and are very reliable. I have owned ARC and Cary tubed power amps and they are easily in the same league soundwise. If you need more power consider the V4. The capability to use different output tubes which both the V4 and the Mid Monos is great. I prefer the sound of EL34 tubes to 6550/KT88s but you can use either in these amps as per your liking.
BTW, The mid monos at 40W/channel drive my 89db speakers to more than adequate level and play as loud as the 100WPC solid state Belles Power Amp I was using before. Tube watts seem more powerful and satisfying to me than solid state watts. I see there are some used Quickliver 80w monblocks for sale at Echo Audio.
