Luxman vs Accuphase for Harbeth 40.3 XD

@macg19 I’ve owned the Int 60 and think it would better the Luxman and Accuphase with your speakers.  Luxman imo is a little too cool and the Accuphase I don’t think will give you the fullness on the 40’s that the Pass will.  In my opinion the Pass Int 250 would really control those woofers best of all and all around is also a great amp.

@marco1 I tend to agree; if I'm going to make an end-game change to maximize the potential of the big Harbeth's, the INT 250 is probably the one. 

I've had the E650 and 509X.  They are pretty different.  Luxman has a sharper, crisp, and clean sound without being harsh or in your face.  Accuphase is smooth and warmer, but with a vibrant and saturated tone.  If Luxman, I would be looking at L-590AX II or L-595ASE unless you want to buy new.  No way I would pay $12k for the Accuphase, but some people just love the Accuphase sound and you could be one of them.  I bought a Japanese unit set to 100V for around $8k, and easily set it to 120V by moving a connector.

If you like Harbeth, Pass may be the ticket.  I only have experience with XA25, INT25, XA30.5, and older Aleph models, but in general Pass has the most tube-like sound to my ears, and the most palpable imaging of the 3 brands.  It gives the most "performers in the room" feeling IMO.  It could be too much of a good thing if there's a particular balance you're trying to strike, but you never know until you try.  Pass also runs the hottest, if that's a factor.

@eugene81 Thanks, very helpful. Pass just keeps coming up and heat is not a factor. 

The Simaudio Moon 700i V2 is one of the best sounding integrated amplifiers that still costs less than the most basic new automobile. A new less powerful integrated  from the North Collection 641 was recently released.
