Is it possible to buy a decent tube amplifier in the $2000-3000 range?


I have very efficient vintage  Dalquist DQ 20 speakers.
Am currently running them with monoblock NuForce class D amps.
Also vintage Conrad-Johnson PV 11 preamp.
Any suggestions, new or used for tube amp in the $2000-3000 range.

I would not consider a speaker with a 86 dB sensitivity and a load of 6 ohm nominal, 4 ohm minimum as a "very efficient" speaker.

I would think that you would need a powerful tube amp (100-200 wpc) to drive these speakers well, with tubes.
I am not aware of any powerful tube amps costing less than $3K, sorry.

I don't believe that a 40 wpc tube amp will do those speakers justice.
They probably work best with your NuForce amps.

Not a tube but there’s a steal of a deal Krell KSA-300s listed for sale right now for $3K and that should drive your speakers with some serious gusto. A 185 lbs. of solid America made steel. Might need to nail your furniture down to the floor to stop them from walking across the room...
