Tube amp mono block recomendations

I've heard some nice demos with Audio Note, but for your music preferences and the Tannoy speakers I'd suggest at least auditioning Manley amps.  They offer some of the best bass among tube amps and are a known match with Tannoys.  The Snappers meet your price point when used.  No reason they wouldn't work well with your other speakers too.

Our M-60s work very nicely with the Audio Notes. IME it is helpful to give them a bit of power- while they are easy to drive and a benign impedance for tube amps, I would characterize their efficiency as 'moderate'; about 90 or so dB. So in most rooms 60 watts is a good minimum amount of power.

For this reason unless you are nearfield in a smaller environment I would not recommend a 7 watt amp on this speaker- it simply won't be enough power.

The Tannoys are very nice but here again its helpful to give them a bit of power. Of course this is true of the Snells as well. IMO/IME if you are planning a tube amp, 60 watts should be your minimum target power, but a lot depends your room and listening habits.

Have you thought about VTLs?  Rock solid and deliver extraordinary detail.  Nice amps for the money.  

You may also find a pair of MC75s from McIntosh in that price range.  

You should be able to find some used Rogue Audio M-180 monoblocks well under your budget (they are $6500 new).

I have them in my main system.  They are detailed and dynamic and fairly neutral.  I wouldn't classify them as "bright", they are in many ways closer to a good solid state amp (great bass control, neutral, quiet) than they are to some of the warmer, syrupy tube amps out there.

i have an audio mirror tubadour III dac, which is damn impressive. Vlad builds the audio mirror reflection monoblocks, which may be worth investigating....
