Luxman 590AX II Break-In

Whatever the OP’s issues are, it’s not the Luxman unless it’s broken, of this I’m 100% sure. @celtic66 - You aren’t being irrational. Your experience, and mine tells us that the Luxman integrateds are stellar with plenty of bass.

I’ve suggested a couple of things for the OP to try to help him understand the nature of the problem, ESPECIALLY HIS ROOM. If you have a bad room but won’t consider it or use a tone control to compensate, but instead want to start swapping amps, that’s irrational.

The issue isn’t lack of bass, the issue is his speakers and room combination are ending up with too much treble energy.  Which makes me think of a new post about tweeters before and now.  :) I'lll put that elsewhere.

I have followed your advice regarding tone controls. Reducing the treble and increasing the bass makes a slight improvement. I have been positioning with small improvements. Interestingly, the loudness button does give me more body and is more pleasurable. But I don't think loudness should be engaged at all power levels to provide listening enjoyment. I have contacted a dealer who is both very knowledgeable about KEF and Luxman, and they stated that the 590 might not be the best combination with the KEFs. The KEFs are power pigs and require tremendous power to bloom. I will certainly give it some more break-in time, but my only option after that is more power. I know many state the prowess of the power output of the mighty 590AXII, but the amp still has limitations. All in all, I greatly appreciate your guidance on how to troubleshoot!!!

Happy holidays to all!

So that's a 30 Watt Class A amp inside a 120 W AB amplifier.  It is essentially a 507 (which I have) with more heat and bigger power supply. 

I don't think the amp is the problem.

I just realized these have 5" bass units. I’ve never seen a speaker with a 5" bass unit that did well.

I’m listening to 2 ways with 6.5" bass drivers with my Luxman 507ux and having a very good time. Maybe you need Fritz speakers instead. Call him, last I heard he had a Luxman integrated as one of his test amps. Worked great.

Note that I am output limited here.  If I want high bass I simply need to add a sub, but the bass is still tremendous for the size.

Echo Audio Portland, OR is big into the KEF line AND they recently sold me their Luxman 509X and they are really smart.  Surely some valid constructive insight there.  Phone 888.248.ECHO (3246) or 503.223.2292  /  Email info@echohifi.com
