Best Integrated, period.

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.

The biggest mistake people make in buying intergrated amp is to buy the miniturised version of seperates,the classic example at the moment is the new Pass lab intergrated.It is nothing more[just like most other intergrated amp] a single chasis version of their seperates...

You should look for brands that makes Intergrated amp for a living,and believe me Neodio not only look interesting,it is [like Lavardin]unique..

I have also listen to all of the Int amp in your list and the Vitus and Krell are definitely in the top 2[depending on your taste,they are as different as Obama and McCain]

To these ears of mine KRELL FBI is the best sounding krell products
