I have an L-507z. I bought a demo unit from Japan. I live in the US.
Luxman pricing is all over the place right now. For example, here is the Japanese retail vs. US retail for some of their integrated amps:
- L-590AXII ¥ 638,000 $9495
- L-509x ¥ 858,000 $9995
- L-507z ¥ 693,000 $8995
- L-507uXII ¥ 528,000 $6500
I think they are in the middle of revamping their product lineup. The pure Class A products (L-XXXAXII) are discontinued, probably due to pressure to put out more eco-friendly products. So not totally sure the L-507z is the totem-pole equivalent of the L-507uXII
