Going linear - The Luxman 507ux


No one panic, but I just picked up the last Luxman 507ux in the US. About 110w/ch with power meters. 😀

Ill compare them directly with my Class Ds at home.

OK, so the amp is barely warmed up and I’m hearing some of the usual early onset effects.


First, they are not destroying my Class D’s yet. For sure, 95% of the common wisdom about Class D sounds is not evidenced here. My previous comparisons, Class D to Parasound said the same.

The Luxman barely turned on has a high "shimmer" factor. If you imagine what big sheets of metal they used for thunder sounds and cymbals, you get what I mean. However, as @dgarettson (probably wrong name) can attest, caps often sound like this before they break in. He called them "splashy." After this, electronics often calm down and that air and shimmer goes away.

Is that going on here? I don’t know, I’ll know by the end of the week. While it does not make my ICEpower 250 ASP modules sound suddenly bad, there is a lot more shimmer and air, almost a touch brightness. By comparison, the ICEpower sound veiled.


However!! I’ve heard this veiling from linear amps as well. So we need to stop talking about Class D like we are in the 1980s. Let’s just treat them like any other class of power amp.

For the Record, the ICEpower modules I am using are long in the tooth design-wise, so like any other amplifier, just because I am critical doesn't mean you should apply these criticisms to ALL Class D amps.

ICEpower, Texas Instrument, Hypex and others have continued to develop Class D. I've not heard them recently though.
My girl kittie keeps sitting in the sweet spot since I brought the Luxman home. High praise.

She also liked the bedroom setup. Monitor audio with NAD 3020D.

My main Class D's, not so much.
Hello Erik How much was your Digital amp? What brand and is it a integrated ?
as I am sure you know the latest digital is noticably better today then even just 2-3 years ago.  I have a digital integrated from Denmark Gato Audio and
they use  Pascal modules ,which then are modified and seperate analog input,output sections . Just sounds like a really nice warm sounding Amp.
luxman make nice products they have been out for over some 80 years or close ro it .their Vacuum Tube stuffis very good also. If this model a class AB first 10 watts in pure class A ?   
This is a surprise . You’ve been so busy defending class d recently . Did you buy this unheard ? in your own systemÂ
