Luxman L-509X

Ok, well best of luck to both buyers and sellers at those price points.

I was about to purchase the L-590AXII after reading a rave review from Steve Huff’s site but stumbled upon this thread saying the L-509X trounced the 590AXII.

The 590AXII will be matched with Marten Duke 2 speakers as the Class A of the amp may bring the speaker to a higher level of performance when compared to my existing solid-state amps.

I spoke with someone yesterday who has considerable experience with Luxman Class A, and their counterpart Class A/B Integrateds. His advice was not surprising. In short...with a warmer balanced speaker like Harbeth, he prefers the AB amps. However, with a more revealing, neutral (if you will) speaker like a Kharma, the Lux Class A will give them much needed warmth. I use Kharma and Harbeth because I have owned both and consider them sonic polar opposites.

Fjn04, that is surely useful. Currently I have Harbeth and Marten and it is true they sound very different from each other. The Harbeth sounds great driven by the Naim pre power solid state amps (they sound soft and dull driven by 7 other amp combinations I tried). Nevertheless the Naim is not a good combination with the Marten as the sound is too spotlit, rough and unrefined.

The Marten and Kharma are quite similar in sonic character I believe, and I would suspect (and hope) that the Class A L-590AXII would be a better match to the Marten than the Naim and L-509X.

Interesting.  I went from Parasound to Luxman 507, and it was in fact getting rid of the warmth that I needed, not to mention that the Luxman has more intestinal fortitude.  Basically more extended at the top and bottom with a better midrange.

I've not auditioned the class-A Luxmans but this tells me I'd probably not be very happy with them. :)
