Viva Solista, provided you have a sensitive enough speaker, I am not sure how you can do better. Only 22 watts, but SET watts, it controls my 89 db Acoustic Zen Adagios with ease. I have not heard better and I have had a few amps, Pass labs Akleph 3, Karan K180, Lavardin IT. The Solista easily tops them all, but not with warm coloured tube sound. The sound is neutral, fast, even across the frequency spectrum, no base deficit
