Luxman 590AX II Break-In

@builder3

The Luxman site says 30 wpc @ 8 ohms:

That is low power… while it doubles into 4ohms… we usually compare at 8 ohms. Since the speakers specify needing 50 wpc. Typically I found that amps at or larger that the max for the speakers to reach their full potential. I would feed speakers like this with no less that 200 wpc from a high current amp.

As a basic test, and to get a base point for positioning your speakers, go to the Cardas site and put the room specs into the calculator and try repositioning the speakers using that first.

Its by no means a perfect solution, as there are so many variables in a room, but it will get you close to a decent set up.

just a thought.

What speaker cables?  I ask because my Class A 30wpc Sugden A21SE (older version) is very cable dependent.  It took some real experimenting to get something right.  Finally settled on Decware Silver Stix.  Duelund also worked.  All others lacked bass and the midrange was thin.  Kind of lifeless.  Best of luck.

I actually own the Luxman L-590AX (not the newer MkII version). Early on, I read everything I could find on the amp, which isn’t a lot.

Here’s just one item https://beterbeeldengeluid.nl/wp-content/uploads/2017/01/HFN_Luxman-L-590AXII_lowres.pdf

For whatever reason, Luxman seems to only publish the Class A output specs. It’s easily more powerful than that, and driving the OP’s 4ohm speakers should be capable of putting out over 160w/channel, and well over 200 when the impedance dips down to 3.2 ohms.

I think I am experiencing the same thing you have! I know many have stated that room size has an effect, but I heard a pair of KEF LS 50's on the Luxman 20 W Class A in the same size room as mine, and the bass was jaw-dropping for a speaker of that size.
