What ever happened to Krell ?

To anyone who is a Dan D'Agostino fan, go audition one of his current amps from D'Agostino Master Audio Systems. I did, and bought an S-250. I found it more musical in my system, and to my ears, than at least a dozen competitors, both tube and solid state.

I know this is an old thread, but for anybody who might come across this in 2020, I want to say that I'm a recent Krell Konvert and I think the Vanguard and Connect streamer are mind-blowingly good. I had a wonderful Benchmark DAC3 and very good class D amp and the Krell kombo absolutely krushes them. I paid the same used as the others cost new, and I'm in a different galaxy of clarity, power, bass grip, soundstage depth. 

Which Krell are you using?

Krell was the master of doubling down,........what happened??

 Stereo, monos, not close to the once doubling down. 
Did they not use enough transistors, or use a small power transformer?

No one ever really doubled down if you look at the measurements. Companies understate the output at 8ohms so it looks like the amplifier is doubling at 4ohms. The trend now if to give the actual 8ohm power output and the actual 4ohm outputs. Some reviews can actually make it look like you are getting better results. The review may say though X amplifier's state output is 500 watts into 8ohms we measured 650 watts! It was always 650 watts and the company already knew it. They just made the math "perfect," for example by saying something like 500 watts into 8ohms and 1000 watts into 4ohms when it really was 650 into 8ohms and 1000 watts into 4ohms. Pick an amplifier that is stated to "double down" and then find a review with actual measurements.
