Gryphon vs Luxman vs Accuphase

I’ve owed all 3 models, well not exactly (I had the Accuphase E-600).  They are all great amps but have “personalities” of their own. Much has do do with what the rest of your gear is, music preferences and what type of sound is important to you. I’m not sure any one of these three are better than the other two.  I would say they are different. 

Based on my experience, I have found the Luxman to be the best value by far and probably has the smoothest sound.  The Diablo 300 has a strong authoritative command of the low ranges but can in some cases, be a bit harsh on the upper frequencies.  The Accuphase E-650 is supposed to be much better than the E-600 but I have not heard the new model. Accuphase seems to be a bit more dynamic in presentation than the Luxman.  Class A does have a certain magic to it so the Accuphase and Diablo 300 (at least for the first few watts) have the Class A magic. 

It’s all about synergy though and the incorrect choice of cables and/or interconnects and other components could yield less than optimal results.  Try to find a dealer that would allow you to do an in home trial for a few days.  

You can’t really go wrong with any of the three.

Thanks @greginnh You may be one of the few that have heard a variation of all three company's integrated amps. Did you think that the Luxman lacked any in the dynamics vs the Accuphase or Gryphon? I currently have a Line Magnetic 805ia which is Class A and comparing to the Primaluna Dialogue Premium HP which I also had at home for a while to try, I found the 805ia to be much more of an enjoyable musical experience. More dynamic, more depth and clarity vs the presentation of the Primaluna. 

My speakers are Spendor D9's and my source is the PS Audio Directstream Junior. Unfortunately, no local dealers for Luxman or Gryphon anywhere near me in Seattle. 

freesole, you might also give the new Luxman L-590AXII a listen, if you have the chance. Class A to 30W/channel, then A/B up to about 90W into 8ohms.

Yes, I love my class A Luxman L-590AXII.  Before Luxman, I was using the Hegel H360 and was thinking about upgrading to the Gryphon Diablo 300.  I've heard the Diablo at the audio show and loved the sound.  But thanks to @greginnh for recommending the Luxman to me.  I took his advice and got the Luxman without any audition.  Now I don't have much desire to get the Diablo.  The Luxman was way better than the Hegel H360.  I've never heard the Accuphase, but I don't think you can go wrong with any of the 3 amps. 

Agree with Greginnh, its very important what speakers and what are the speaker and power cables you will use with these amplifiers. A lot of people underestimate the importance of cables and system match.
