Dan D'Agostino Helius dual monoblocks, 1500w @ 8ohms

That’s an old issue, nearly 10 years old. ’Recently recalled’, on a 10 year old design.

Eg, that would never really happen in most other consumer industries - that would be end of life stuff that is expected.

We know that we expect longer lifespans out of audio gear, though. We hope for 10 year old audio gear to be the equivalent of maybe mid 30’s age (compared to human lifespans). We’ve come to expect and demand it as part of the high end package..

Overstating it in the negative is not the best thing to be doing....(not that I need to be here defending anything -just sayin’, kinda thing. More like playing the other side of the reasoned debate table).

So far there are no photos of this amplifier anywhere. 
It doesn't exist.  It is a myth.

No ones even mentioned this thought; Maybe some of us have a limited range of hearing! Oh my! Could you be one of those? Really, I go to audio shows and super expensive speakers and amps don't do anything for me. Maybe, just maybe my ears aren't that great. This is the untalked about subject. Does anyone else think their ears aren't up to hearing the uber best? Joe

I find Krell to sound better than other amps on my Martin Logans.

Bought one vintage Krell from the nineties last year, and now I have 3 different designs. All Class A.

It's great that they still can be brought back to original operation at Krell or by some certified techs spaced around the USA.

Most Krells are just what's needed to stay flat in frequency response driving into the .9ohm load load that nearly all ML's have in the HF.
  
Sure other amps will drive them, but their frequency response will look like a tone control, instead of being flat across the audio band into the ML's.
