Is the Hegel H-20 better than the Parasound A-21?

You are not understanding what the manual is saying, they are saying that the amount of electricity consumed with lower sensitivity speakers will increase, and this amplifier is a beast based on original Krell Class Designs, think KSA 250, the amp was designed by Dan D'agostino originally and has no problem with less efficient speakers.

My last post was not on the subject of sensitivity. Rick did point out the new 8008 will drive 4 or 3 ohm speakers. I was just relaying info from my conversation with him. Your added info is appreciated. So what you are saying is that the earlier Aragon amps were built on the Krell platform. Early Krell amps were cold and shrill and were mocked by Audiophiles and Dan was kicked out of Krell. Makes sense that the early Aragon amps were cold and shrill as well.Thank God Aragon/Indy has better Engineers that have turned things around. D'agostino is way overrated but is very good at marketing himself and Engineers such as Demian Martin, Nelson Pass, Eric Lauchli and John Curl blow Dan out of the water.

You are not understanding what the manual is saying

Oh, I do understand what the manual is saying. I raised a very valid point: is this amp stable below 4 ohms? You should know that 4ohms is not an absolute fixed value.

they are saying that the amount of electricity consumed with lower sensitivity speakers will increase

This is just common sense.

and this amplifier is a beast based on original Krell Class Designs, think KSA 250, the amp was designed by Dan D'agostino originally and has no problem with less efficient speakers

This is irrelevant concerning the 8008 amp's behavior since they are not the same design.

Hegels are in a very different level altogether - Parasound, is very much inferior both in sound and engineering - just my opinion.

I owned the Parsound A-21 it was very well balanced I put in
4of the aftermarket fuses in there, as well as a good $600 power cord
Then it had a bit of warmth and nice detail.
The Hegel 20 is a better amp in every respect, with a warmer character
But images are much more palpable, and front to back layering is much denser micro dynamics are more distinct,and bass is just as fast but better
Articulated and formed .that is why you rarely see a H-20 up for sale.
