Have not done it but done a lot of research investigating the possibilities. Class D amps have kept me from having to go there (tube amps) to-date.
Not in general interested in large bulky speakers required for best performance in general with low watt tube amps.
However, to test the waters on a limited budget, I would likely go with Klipsch Heritage line and pick a tube amp from there. Could be Heresy, Forte, or Cornwall depending on specific room and what would provide the most flexibility there. Would also consider Spatial Audio in the right room or Fritz speakers (easy load to drive) for something more compact. I would also probably at first be inclined to give it a go with my existing Ohm Walsh speakers, but would expect to need at least 20 watts or so or more.
With a limited budget, practically, it would be hard to talk myself out of trying this
as a first stab. Lots of good reviews, good build quality, flexible, value.
Beyond that, if needed, on a grander budget, amps I have heard that I would strongly consider come from companies like Audio Research, Rogue, Jolida/Black Ice, Conrad Johnson, Linear Tube Audio, Audio Note and I’m sure several others.
