Seeking hot running amps

Well, there is more than just "HEAT" when there is heat, there are tradeoffs, for every degree something runs hot, there is a reduction in reliability, as well, the heat comes from somewhere, it's energy, wasted energy, you wouldn't run your car full throttle all the time an use the brake to go 30 miles an hour, there are intelligent ways to use energy

Joule Electra OTL tube-based amps. I have a pair of their 100 watt versions in my dedicated Canadian basement listening room. I close off the heating ducts to the room and turn on the amps an hour before I listen. Works great for me - I STILL have to have a blanket on when I listen to music in the winter.

My vote goes to the Mccormack DNA-1. The fact that it operated so hot, actually contributed to my getting rid of it. An excellent sounding amp.

Thanks

Allanbhaganinfo, your analogy does not work. Class A amplifiers generate heat because they are on all the time. The engine in your car makes heat- all the time- because it is on all the time too. But it is not correct to compare the two!

Class A amplifiers get used not because they make heat but because they are the best sounding amplifiers made. IOW, any amp that is not class A won't sound as one that is (all other things being equal). Especially when one is investing thousands of dollars in an amplifier, one ought to be aware that the sound quality investment is better served by an amp that is class A (and runs hot).

It is assumed that the amplifier is also designed to handle the heat that it makes- we've been making class A amplifiers for the last 28 years and so far the heat of the tubes has not caused us any reliablity issues- and we get good tube life too. Its all in the how you handle Class A requirements.

I'd like to hear someone tell us how Atma Sphere amplifiers are anything BUT reliable. Personally, I haven't come across a more reliable amplifier, be it Class A, Class A+, Class A/B, Class B, Class D, or Class XYZ.

Yes, if you want heat, a Class A amplifier is your ticket. Nice in the winter. The power draw isn't a positive, but that's about it when it comes to drawbacks. I concur that Class A often goes hand in hand with great sound. The Atmas being as good a Class A amplifier as you'll ever come across, particularly if tubes are your cup of tea.

Never understood those who were running their Atmas in Class A/B mode. As I like to say, "In for a penny, in for a pound." In my opinion, you run your Atmas the way they are supposed to be run, with the kind of speaker they are supposed to be mated with, or you find some other amplifier.
