Luxman leaves me wanting

So you've got 30 wpc of Class A Luxman super stable current power.  And you don't like it.  It's okay.  Class A is a taste.  Nothing wrong.  I lived in the tube world for years and left it because my tastes changed and I now like super fast dynamic non-lush romantic tube sounds and now I'm a Class A and A/B active speakers and oh yes, I run a Luxman 509X.

Some of the advice given above may suite well.  Some is to be discarded.  I assume you are here because you thought someone might know more than you.  Well, maybe not.  For 8K, I'd go with Manley used 300B pre and Snappers.  And yes, I've owned plenty of Manley, so it's not the "I heard that...".  Have fun with your choice.  Cheers

That 590 has 30 wpc in Class A, and about 65 more in AB, into 8 ohms.

I can't offer much advice, maybe borrow or try some different cables, to start.

I have the Luxman L-590AX, which is the version prior to yours. None of the issues you mention describe my experience, but my speakers, etc, are different.

Good luck

I’d suggest upgrading your source components. Your amp and speakers are revealing their limitations. Better sources will fill in the sound and flesh out the tone.

@steverrino,  perhaps the Luxman and your speakers are not an ideal marriage but you should not be hearing what you describe. We know nothing about your room acoustics nor the shape, size or structure. Cables and different amps at this stage will not achieve much, not if your listening position places you in a partial null of which there are many in all untreated rooms.

It is difficult to conceptualise the damage strong early reflections cause, something that can not be solved with EQ

A smart suggestion offered by a poster above is to consider subs, an excellent way of taming peaks and nulls whilst also bringing lots extra to the party. An improvement is gained across the spectrum.

I've heard Devore 0/96 driven by a 300B single ended amp sounding delightful.

The Luxman is a midfi sound. Try modwright or quicksilver
