How much more power do 2 Bryston monoblocks use?

Thanks to all for the advise and suggestions.  While selecting a new amp based on how much heat I can get off the heat sinks appeals to my sense of whimsy, I'll have to pass on that idea.  If, for no other reason than the effects of heat production, which would be very welcome in the months of December to March, would prove to be equally unwelcome in the months of June to September.   Actually the heat situation is pretty manageable and turning the heater down to the lowest level when I go in and start listening works very well and produces no noise that I can hear.  On top of the heat off my amplifiers I also gain heat from some tube preamplifiers as well as two large candles.  There are times I don't need the heater at all, but I have played music at full volume, with the heater at full volume too.
I guess I can live with a Bryston 4b st. Power-wise, it's just a touch more powerful than my ADCOM so everything should be fine.  Hopefully, I can get it to sound as good as my ADCOM.  (That was actually a very serious statement.)

Thanks!

As someone suggested earlier, something like a Krell KSA150 or 250 would give you all the power you need for the 1.7s and the heat to keep you warm in winter. But seriously, I wouldn't put the space heater and the amp(s) on the same circuit. Aside from the current draw the electric heaters introduce noise which will affect all other gear on that line.

@Toolbox149, Is it possible for you to run one or better yet two new dedicated lines into your music room?

If not can you run an extention cord to a different outlet in order to use your electric heater?

At full power into 4 ohms, a Bryston 4B can can consume all the power available on a 15A line. I think it works best on its own dedicated 20A line.

No in my last 2 houses I have dedicated 20 amp circuits for my audio gear, I don't think pwr will ever be a issue.

In your situation you probably will be fine especially turning down a heater like you said.Maybe get class a amps and have the best of both worlds.

Best of luck to you,

Kenny.
