Luxman L590AX vs.590AXii

Enjoy it.

The main difference, as I recall, is a beefed up output stage in the MkII.

Edit - Actually, it was the power supply - "The power supply uses a large power transformer with an E-shaped core and a thicker primary wire, as well as eight buffer capacitors of 10,000 uF each, rather than four as in the previous version."

Differences Between Luxman L-590AX and L-590AXII

In order to achieve power without sonic compromise, Luxman implemented its ODNF 4.0 drive circuit utilizing a three-parallel push-pull structure with three-stage Darlington. A Luxman 'Ultimate Efficiency Power Transformer' – an EI type rated at 615VA – forms the heart of the amp's power supply, with plentiful regulation ensuring an unshakable response to any load fluctuations. A high-capacity block capacitor contributes to L-590AXII's ability to deliver lashings of power yet remain firmly in control, while the amp's low-impedance transmission design, carefully selected custom components and short, fully optimized signal paths deliver maximum sonic purity. Compared to L-590AXI, which had only four block capacitors, L-590AX MarkII has eight in total – four each for left and right, the same configuration as Luxman's M-700u. Similarly, whereas the L-590AXI had four output boards, the L-590AXII has eight output boards to drive even more difficult speaker loads with ease.

Personally, I'd buy the newer version, if nothing else, it's newer. I don't know what your situation is, money-wise, nor the cost of either. I'd opt for a 4 year old amp over a 10 year old one. Either amp will drive those speakers, I think there's probably little difference between them when it comes to actual listening.

Thanks, guys. I guess the other deal for me is the limited number of these available, since they're now discontinued. Not sure what Luxman's plans are at this point.
