Tube integrated amps

Thats a little different, if your room is small or medium
in size than either the Manly Stingray, or possibly Canary CA-608(?) would be worth looking into.

Or a Hybrid: (tube pre/mosfet amp) Unison research

And if you decide solid state: I've had the Ayre AX-7e, very refined & natural.

Have Fun.

those speakers will be tough on a tube rig.

Stingray or Rogue integrated offer great bang for the buck

I'm gonna say 30 wpc should drive the Dyn's. BUT at what levels?

86db is as much the issue as is the impedance here.

I'd say look to more than 30wpc on those particular speakers. Like 60 or 80wpc.

I ran a pair of phase tech 2 ways, with 85db, 8ohm, with a BAT vk 60 with no problems. The 8ohm load helped a lot I'm sure.

Will 30wpc tube amps work? I'd say so... but how well is another story I believe.

Without trying first and buying in the blind so to speak? I'd say shoot for more power right off.

Or really, really good quality tube ints with great output Trannys. IMO.

Two tube integrateds that should (theory and practice don't always align) work would be an used VAC Avatar and the McIntosh 2275. Even better would be some more powerful tube separates that drive 4 ohms well (larger Manleys, VTLs, etc). While much of what Williewonka, says is true, you can imagine how good tubes must be to put up with all the issues he mentions. In this case, and at your price point I think SS is "proabably" the way to go, at least 100 watts.
