This is for Georgehifi especially but others can chime in.

Thank you everyone for a spirited conversation. I follow these forums regularly and enjoy each of you. @keithr What preamp were you using?
   Simaudio 700 is an awesome match with the Dynaudio C1 and I should definitely consider it. 
  @audiotroy seem to get a bad rap on here. They are trying to sell gear but I take their enthusiasm as a love for the product. 

T+A was imported by Quartet marketing about 14 years ago. I have been carrying T+A Products since then. Yes T+A was also imported by Dynaudio for a few years because they showed together for a few years in Munich also.
T+A is brilliant stuff. If you're in Los Angeles, Come by and experience every product they make. Yes including their Mono Blocks too.

@georgehifi 
You talk like only BJT stages do that. MOSFETs have no trouble with that either, and they don't require as much thermal runaway protection. 

@audiotroy 
More opinion. No facts. Yawn. 

i found audio research pairs nicely with dynaudio (both their solid state and tube products). worth giving klaus at odyssey audio a call too - his amps can beautifully drive any speaker.

they don’t require as much thermal runaway protection.

You keep saying that and they have it, talk to Gryphon and Krell who make some of the highest biased Class-A amp there are, and what do they use??? BJT’s WHY??? Because they give the best current ability.
And 4 X 150w pure Class-A that I made, BJT’s, and yes they were water cooled if you have doubts about getting rid of the heat.
Sure if your a dumb a**e and can’t design for s**t you can get thermal runaway I expect that from a backyard diy'er, but you don’t see any of the above doing that. And they will, I repeat, WILL out current any Mosfet amp into low impedance’s. Sorry but you have your head in the sand if you don’t know this.

Cheers George
