Different amplifier class for different music genres?

I was reading a review of the Gryphon Antileon Evo in another forum and one user was saying that in the High bias mode the amplifier was excellent for classical music but not so good for metal or hard rock, perhaps softening the transients. For metal or hard rock he preferred the Low bias mode and he suggested that the Gryphon Diablo will be more suitable for this type of music (of course one is a final amp, the other an integrated one).

So the question is: does the class of the amplifier matter or better suit the type of music you are listening to? 

I have never owned a class A amplifier and I am itching to try some. I am currently using Hypex based diy monos driving Vienna Acoustics Mahler speakers.

Thank you all. You learn every day. It has been a long time I was wondering if my amps have synergy with my speakers. I am not prepared to change my speakers at this point so I would like to try different amps.

@mijostyn. Thanks! It sounds like you know my speakers. Yes, they are well designed but could be difficult to drive, they are nominally 6 Ohm load but they do drop below 4 Ohms at some low frequencies. 
Now I need to decide if I want to 'just' change the power amps or go the integrated route.

Not really but I had some Quad speakers once, and chucked some EL34s into my monoblocks, just to play with that setup.

Absolutely wonderful for any chick singer, or anything like that, fell right over when asked for dynamics and slam.

Sold the Quads and put the 6550s back, my stuff has to play Zappa well. ;)

+1 for Zappa. To me, Zappa's DDD recordings are an excellent reference.

If it can’t play all music great it ain’t so great.

Have any of you wondered about some of the comments I see about amplifiers and speakers when you consider what a real live band (especially rock) is using to create their sound.  They are using a guitar amplifier and speaker combo, PA quality speakers and amplifiers, various quality uncalibrated microphones, a sound mixing board, lots of cables no self respecting audiophile would allow near their gear and then I see all of this talk about transient response, tube amp or solid state, Class A, A/B or D etc. with no thought about what the original source was capable of producing or how it compares to an actual live performance. 

Maybe for purely acoustical instruments with excellent mics and recording equipment one could capture something that would warrant these distinctions but somehow I doubt it.  When most of the instruments are electronic and being mic'ed and amplified and played through PA quality speakers you can reproduce the sound best with the same type of equipment.  No matter what you do you can't get better than the original source.
