Big Krells Have Vanished From The Used Market

Tubejuckie64, I already had 10 gauge copper wire in attic that I installed,  I installed the whole package myself,  krell told me to do all this to run alot cooler and sound better,  I complained about running hot with 20 amp breaker,  talking about money well spent,  the 20 amp breaker was chocking the life out of the amplifier literally!, this a very substantial up grade,  I couldn't believe it,  like a component change ,😎

Those MRAs had to be the most impressive amps ever put out.  Huge but awesome.  Personally don't care about class D although they are better than class A or A/B for guys with bad backs.  

audiolabyrinth, I do agree that having greater supply can have an effect on the sound of the amp in that it can lessen the time required to recharge caps. I rewired demo rooms at a store I worked at years ago in order to accommodate the higher end amps we had and it did make a big difference in how they sounded. However, it doesn't make sense that having a greater electrical supply will lower the operating temperature. The heat is a result of current, therefore, the more current passing through the amp, the more heat created. It's no different than a burner on an electric stove - the more current you allow through, the greater the heat created.

Noble100 made an interesting point....MHO.....

Not so long ago, a bet was made that computer printers could be combined and made to add scan, copy, and fax functions.  Don't know if anyone or any organization collected on that bet, but it's pretty obvious that we 'won' the benefits of it.  That combination is pretty much the default now...

I don't have any doubts that class D will eventually match all existing classes in performance, even in the high power versions.  This will take awhile yet...all advances generally do.  These advances are usually driven by demand, the typical market forces that make up our civilization...whether we like that or not is more or less moot.

You want the class D of your dreams?  Vote with your wallet.  Buy what you perceive is the best of the current litter Now and start driving the technology of the future.  That's what's drove the market to where it is now and it's still on the move.

Stop whining and wishing...get out, up, and help push.

I have Krell fpb 750 mcx + kps 25 cx mabey sellin them .
