Pure Class A shootout


Hi after doing a lot of research and listening, I think pure class A is still the way to go for me. I'm wondering if you have any opinions on the following amps and how they compare with each other:

1) Gryphon Colliseum (mono or stereo)
2) Gryphon Antileon Signature (mono or stereo)
3) Pass XA 160.5 or XA 200.5
4) Krell Evo 2

They will be powering Rockport Altair's or maybe Rockport Arrakis (still debating that one too).

I see a few dilemmas. For Krell, it seems like the spirit behind their products Dan D'Agostino is no longer with the firm and thus maybe their brand/lineup in the future may be compromised. Also, Krell's preamp reputation is not as good as their amplification. That's similar to Pass as well - great reputation on the amps but not as reputable on the pre-amps. Don't get offended as I'm only talking relative terms (i.e comparing products at very very lofty levels). For Gryphon, their amp and preamps are supposedly top notch, but right now the Euro is extremely strong vs the US$ and I'm thinking I should be picking up something American as it's more of a bargain. Gryphon + Rockport is a "formula" and I know I can't go wrong with it but I'm wondering if there are other options.

So I guess the question is:
1) Have anyone ever compared the best Pure Class A amps? How do they compare with one another? Yes I know they are all good at this level but unfortunately I have only listened to the Gryphons mated with Rockports.
2) Any other options that I should consider? No tubes please as I have no desire to mess with tubes.
3) Should I even compare/consider the older pure class A amps like the ML 33/33H? i.e are the new pure Class A leaps and bounds better than the older reference lines?

Thanks, -Isaac

I agree with Rtn1. Try an audition amps with the Rockports. Your perception based on lived experience will help you navigate your purchase decision process. In addition, there is something to be said for the cognitive knowledge of the technology used, if you are convinced that it matters. The perception of what will make one satisfied is personal - Class A or not, tube or not, you set the value for the criterion in question. In the jewelry business with precious stones, people talk of mind clean vs. eye clean. Some wish to purchase flawless or near flawless gems because they know they are so, even if they cannot see the imperfections of other stones with a 10X loupe.
considering the prices paid for krell; i have to say that they are not worth the price.there are better sounding amps out there at more affordable prices both class a and other.
thank the audio gods that we have so knowledgeable audiofiles to protect us from these over priced only fair sounding equipment! i desided i am going to sell everything and copy your set up. i only hope i can find a pair of "monarchy audio se-100 monoblocks". may the gods be with me!
ok koegz no need to get snotty.are there better amps than my monarchy?YES.however i cant afford the :best: and YES THERE ARE STILL BETTER SOUNDING AMPS THAN KRELL.
You're quite correct Energizer but Koegz has every right to collect and play with dinosaurs.

Everybody needs a hobby.
