which tube mono blocks?

Try the Thor Audio 60 watt tubed monoblocks. I've seen them for sale for about $5000.00 a pair. They sound great.

I'd see if those Coincident Dragons would work with those speakers and put the rest towards a Porches 911!I'd still walk away with a chunk a change

i just acquired a pair of quad 57. i am looking for a tube amp. although i am considering a dyna stereo 70, i just missed the opportunity to purchase a cj mv 125, which is my first choice.

yesterday i heard an accuphase 50 watt amp, from the late 80's. i would love to audition that amp on my quads.

FWIW: While researching tube amps also research tube types. My VTL's can take 6550's and KT-88. I like having that option. Search the forums there are many that go into great detail about how a particular type/brand sounds.

I've got a Dynaco St70 running my Quads. I've had the amp wired in triode put gold plated rca's and had 5 way binding posts added. It also has a tube preheater installed. I run the amp with a Dynaco pas 3. I have a Krell,Classe,Avi monblocks, and Opera Consonance M8oo monoblocks. The Dynaco is still my favourite. It puts out about 12 watts a channel. By the way i've never ran anything but tubes on the Quads. After 50 years they still have the best midrange of any speaker made. One last comment. The m800 i also run them in triode at 35 watts per channel and they sound sublime.
