Questions re:  GaNfet technology vs other designs.


How do the newer GaNfet technology amps compare to the HYPEX NC400, HYPEX NC500, HYPEX 1200 and PURIF Audio designed amps in terms of sound quality? And also how do these GaNfet technology based amps compare to class A and class A/B amps for sound quality?

It seems several companies are offering GaNfet Amps. For example, please the Orchard Audio Starkrimson 150w gan amplifier and the Atma-sphere Class D power amplifier (and several others).

GaNfet is claimed to provide excellent sound quality. Several class D mono blocks offer great sound as various reviewers have reported. I noticed there are several GaNfet technologies power amps available but not many integrated amps. I wonder why. 

Maybe the better question is GaNfet Amps really for prime time? Your comments on GaNfet Amps are requested. thanks....

GanFet, Class d, Purifi, Class A, High Bias Class A/B, tube, ZOTL, AHB2 THX...a lot like the colors of automobiles....there are favorites like white and grey but there is someone for every color.  And, what looks good to you this year may not be so appealing next year.

When it comes to audio gear, you can read the reviews but until you try it in your system in your room with your music...there is no way to know whether you will be moved to the point of saying..."I gotta have this".

 

Ralph, is it possible then to get different technology amps...say OTL, ZOTL, Gan, Class A....to sound almost identical if you can get the distortion spectra for each very similar to each other?

Presumably there is better measurement equipment today which would allow the "fine tuning" of the various amps I mentioned in a fashion that might? allow them to sound very similar??

Leo, thanks for the link to the thread over on SH.  You have to be really brave, or pretty sure you have a great product to put it out on a public tour with no oversight as to what will be said about it....and obviously, lots of people are loving it.

A couple questions...did you have a design objective with respect to 2nd/3rd harmonic distortion or were you just going for the lowest overall distortion and then final tweaked for sound.

Congrats on the reviews and continued success!

Leo...wow, thanks for the quick answer...I take it that flat wire with gain is another way of saying that as much as possible, get the distortion, phase shift, etc. as low as possible so as not to "create" an amplifier sound...just let the sound from the source/preamp come through unaltered.
