Gryphon vs Luxman vs Accuphase


Thinking that I may bite the bullet this year and get into a Gryphon Diablo 300 but before I consider shelling out that much, wanted to get some input from any of you that have heard this amp in comparison to Luxman or Accuphase. The 509X from Luxman costs half that of the Gryphon and is more within reach. The Accuphase E650 is not that far off the Diablo 300 pricing. IF the Gryphon is better in your mind, curious to hear whether you think the Luxman or Accuphase come close?

It sounds like all 3 have rave reviews. One is a class A while the other two are Class A/B.

Freesole it sounds like you are enjoying the 509axII over the 509x. Is it enough to draw you away from the LM 805 tube?

@rwbadley I think it really depends on what you need. The 509X provides a little more flexibility due to its higher power output. It is an amp that will handle pretty much any speaker you want to throw at it. If you have power hungry speakers or think you may want to switch up in the future, the 509X gives you that future proofing and peace of mind. It also runs very cool. 

The 590AXII has that class A magic that is so hard to describe at times but can push beyond the 30W Class A into Class AB and drive most speakers well. They certainly drive my 90db @ 8ohms Spendor D9's without any issue. It runs a bit hotter. 

Overall, the sound is just a little different but as you know, being audiophiles, we nitpick over small differences all the time so it's a big enough difference to me to prefer the 590AXII. 

Do I trade in my LM 805 for this? I'm still thinking about it but it sure is tempting! I do like that I don't have to worry about tube life and the heat hazard that the LM has but its sound quality really is beautiful. It's a tough call. 
Thanks for your feedback freesole! 
Think of it this way... the 590axII gives you more freedom to try higher efficiency speakers!

It is a tough call with tubes, the tube lush presence vs ease of maintenance with SS.

Even worse, when I was doing tubes heavily the tube rolling and 'what if I try these' became an interesting but rather expensive endeavor. White elephant in a way- the amp was cheap(ish) but 3,000$ worth of tubes later... ;-)

Now I've rediscovered the magic of tone controls haha

Cheers,

@ rwbadley

I am not OP but have excellent experience in Line Magnetic 508 amplifier.

I inserted Synergistic Blue Fuse (150$).

Mullard ECC85 (6sl7) 130$

Sylvania 1944 vt231 (6sn7gt) 125$

Psavne Acme 805 733$

It really shine with above combination of tube and fuse.

It is almost comparable to my Silbatone 300B SET int amp fitted with original WE 300B (25k$) at transparency, details.

If you are tube lover, LM805 or 508 will fit your need.
