Luxman L-509x for B&W 803 D3

Surely meant gobs of power.  I limited experience with either.  Once upon a time 125 WPC was zalot of power.  The current delivery is what I think you're concerned with .  I would give it a shot. If the amp is no good with your amp then move up. Or ask B+W.

Thyname the Luxman should drive the 803D3 fine, it really comes down to how loud you play and the room size.

We had the 20 Watt Luxman 550 and it drove many speakers really well in a smallish room at a distance of 8 feet from the speakers.

The non Class A luxman are not quite as sweet sounding as the lower powered Class A amplifiers which have a warmer fuller midrange.

So it will all come down to the source and cabling.

Give it a try and see what you think.

As the above post says, your L-509X should be fine.

Thanks guys! It sounds pretty good with my Luxman L-509x, but in the absence of other amps to try, I did not know if would sound even better with something else, more powerful, and closer to maximum spec range (up to 500 WPC)
