I've used Luxman class A amps since a pairing with Devore 9 back in 2008 or so. That said I recently used a 550AXII with the Forte IV and wasn't crazy about the combination. A little too much control and a little bright (not how I would usually explain Luxman). I agree with the above, go with tubes with these. If you want power get a bigger tube amp.
Cornwall IV's with Accuphase E-650? good match?
been trying to source a used Luxman as I've read they pair well with both Cornwalls and a number of speakers I already own
unfortunately they're pretty scarce around me and a used Accuphase just popped up at a decent price
anybody have experiences with this combo as I try and decide to take the plunge?
