I had a nice little Cary SLI-80 integrated for a couple years. It actually makes 50W full power in two channels and is best played into a rather flat 8ohm speaker, but 4 ohm tap works fine too. It has 6SN7 drivers, 6922 inputs, and just about any octal output tube. I used SED 6550s with great enjoyment. It is very pretty, has remote volume and mute, solid as a rock construction. Headphone amp is great. The used value has been rock steady at $1800 since I bought mine 3 years ago. Just sold it for $50 "profit" a few months back, not counting all the tubes I gave away as enticement. haha A very nice little amp.
