Top ten tube amps

The Music Reference RM-9 Mark I or II should be close to the top of any tube amp list. The CJ MV60 SE is another good 'un.

Absolutely any one of the audio note pre and power as wells as the integrateds. Some way behind would be Blue Circle and much further behind would be Jadis, canary audio, Manley, Music reference, CAry, Graff, all of which i have owned.

More votes here for Atma-Sphere and Joule Electra.
Jadis, Audio Note, VAC and Air Tight for Push-Pull designs.
Although I haven't seriously auditioned enough of the top SET designs, one that's impressed me is the Dehavilland. Cheers,

I agree with Ozzy62,I own a Music Reference RM 9 mk 1 and it is among one of the best I have ever heard or owned.I have heard mant tube and solid state amps,but still love the Music Reference RM-9.

a survey such as this is very difficult only because it's too open ended, and subject to personal favorites, vs. test data...that being said some obvious choices are:

1) Zanden 9000 series 300B's
2) Tube Research Labs GT 400 & 800 series
3) Convergent Audio Technology JL-2 Signature
4) Kondo Ongaku w/KSL technology
5) Shindo Labs
6) Wavac HE-833's MKII
7) Lamm ML2
8) Tenor 300 Hp
9) Jadis JA 80's
10) SAP (Strumenti Acustici di Precisione) New Anniversary

Lord knows I've only scratched the surface?
i.e. FM Acoustics, Nagra, VAC, Joule, and so on.
