Accuphase E5000 vs Gryphon Diablo 300

Both great amps and really hard to see going wrong with either, and great speakers as well BTW.  If I was looking I’d add Vitus Audio to your list.  Best of luck. 

@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.

op

given your two choices posed, and given your stated music preferences, as excellent as the accuphase gear is, i would choose the gryphon

Just grabbed an Accuphase e280, $6700, ouch. Did not need it really, but what the hey....was told it was last one in US, with over 3 month wait for next shipment. Privacy increased from $5999 (by $700 bucks, crazy!) , but crazy I am I guess.  So I’ll have this and my Clsss A Sugden, I think I’m good for a long time. Never heard of Gryphon...so can’t be of much help.

you should listen to the burmester 032, best i have heard
