Going linear - The Luxman 507ux

Quick off subject post but speaking of remotes: The Xfinity remote that has voice recognition and that lights up when you pick it up is first rate in form, function and quality in my opinion. Who would have thought it?

Hey Erik... how’s your Luxman sounding now, another week in?

+rockrider, I am also wondering.

Hi @rockrider and @jetter

Thanks for asking. Unfortunately I tore down my TV/stereo set up completely, and it too longer to put back together.

When Lily (the Luxman 507ux) arrived, I put her on a coffee table for the first few days because she wouldn't fit anywhere else. I ordered two three shelf racks, so I could put them side by side with the TV straddling them. That took me a while to get back together. The room acoustics are still pretty messy though, I have lots on the floor and the old entertainment center is acting as a big reflector.


Part of what took me so long in this is I really miss having a 5.1 for movies. I have all the extra bits except for a receiver, so I was thinking of putting the sub in between, using it as a center channel stand, and using the "separate" feature in Lily. I think however that I'm just going to have to give all those bits up for now, and hope some day in the future I can have the space for it.


What is helping is that the bass via the TV outs is really quite good, more than enough to annoy the neighbors. :)


In the mean time, Lily sounds pretty good. If I ever really finish getting rid of all this extra gear I may go back and attempt to do a direct comparison between her amps and the Class D's I was using before. That would be an interesting listening party, right?



Best,

E

OK, I think I’m ready to come to a verdict on the Luxman:


For sound quality, I think it’s a better amp than my Parasound A23 and ICEpower 250 AS modules, for identical reasons. It is also better than any Pass amp I’ve heard, for totally different reasons.


Like the first two amps, there's nothing obviously wrong with the Luxman. No noise, no noticeable distortion.


Compared to the first two, the Luxman has a more forward presentation, often called presence. Further, there is good bass extension when needed, which comes through more with television and special effects. The body of instruments from the piano to violins come through more clearly, and the shimmer factor is improved. The first two amps gave a much more distant, back of the hall, sound stage.


Compared to the Pass amps though, it's a totally different story. I find the Pass amps I have heard leaner and frankly, audibly irritating. I’ve heard a very nice set up at an audiophile’s home, and heard many at an audio show near San Francisco where Pass was a sponsor. Whatever it is Pass fanatics rave about it grates on me. Perhaps this is the deliberately extra distortion Pass adds? I also find them limited in the extremes of the frequency response and therefore thin to my ears. You don’t have to agree with me at all, but this is my experience.
