Both are excellent amplifiers and so is the d"agostino momentum.
I listen to classical, as well as blues & jazz, so I would opt for the Gryphon. YMMV, so audition them first.
You won't go wrong with any of them
Accuphase E5000 vs Gryphon Diablo 300
Hi, looking at an endgame integrated amp. The Accuphase E5000 and Gryphon Diable 300 have both piqued my interests and would like to demo. both soon.
I’m a rock, pop, punk, blues kind of guy & will end up with a Spendor D9.2 as the speaker.
Is it worth look in at these two or should I expand my demo. list ?
@rfc, how big is your room and how loud do you listen?
Unless you are filling a very big room or play your music at concert levels, you might not need so much power with the Spendors. I've got D9s and in a 12x17 room and driving them with a Pass X250.8 I never once it had it leave its ~18w Class A bias playing in the mid 80 dBC range. I then switched to the XA30.8 and could play it in the mid 90 dBC range without it leaving its 30w Class A bias.
You might be able to save some $$ unless you specifically want a high powered amp...; one of the many virtues of the D series I really like is it doesn't require an uber-amplifier to make it boogie or sound good.
