Best Integrated, period.

Best Integrated Period = If you can find them:

Solid State: Genesis B-200 Stealth 200 Watts per channel Class A monster. The proverbial iron fist in a velvet globe.

Tube: VivA 300P 22 watts perchannel of 300B magic with balls.

Like David12, I'm also very impressed with the Viva Solista. My friend has his paired with 86bd efficient speakers in a decent size room, but his listening is pretty much limited to small ensemble jazz and classical. With speakers rated in the mid 90dbs or better, I suspect the Solista would play any music with world class results.

You could order VAC Phoi BETA 300.1 and have stepped attenuators fitted in the factory. There are two switchable inputs on the back.

I use many SET amps the better ones a wavac. The FBI sounded great on my SEAS bookshelfs and my 3 way front horn but the SETs all have better musical connection make me listen longer and with more interest than any SS Ive heard. But the FBI still is amazing for SS I could live with it. Since I design loudspeakers I tried a few diferant KCS designs on SET and the FBI.
