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

Easy squeezy. Try an Inspire amp by the famed Dennis Had - They're less than $2k. There are tons of tube amps below $3k, primaluna among them.

Wow, a PV11... I had one of those and loved it. 

Try a PrimaLuna.... very nice, I own one now.  Had a pair of VTLs... best amps I ever owned (well I had a solid state Bryston 4B onces... wish I never sold that).

I might be late to the party, but there's an LSA Statement tube/SS hybrid integrated available on Agon now for around $2K. One of the best hybrid integrateds ever made. Will drive anything with delicacy and grace and power.

Yes, the PV 11 is still wonderful after all these years.
Had it looked at by CJ once and re-tube it fairly often.

I think I should retract my original post as I no longer feel the need for a new amp after buying a new Schiit Gungnir DAC.
It’s amazing! Deep soundstage, wonderful clarity, imaging, and plenty of power without distortion when increasing the volume control.
As someone in the thread pointed out, my 160W NuForce monoblocks are sufficient, especially with this new DAC.
And the amps have great synergy with my speakers.

rv - Did you opt for the Multibit upgrade on your Gungnir? If not, it is well worth the money. If you like how things sound now, you will absolutely love what the upgrade brings. "Upgrade" does not do the MB justice. It really is transformational.

I'm happy to read you were able to keep the Dahlquists and make things work.

Continued great listening to you.
