Audio Research or Luxman?


I recently acquired a 1973 Luxman L-507 integrated amp only to learn that the volume/balance control pots are bad and can't be replaced, but I was able to bypass the pre-amp section and run it with the amp section only, and oh my, did it sound good.

I was very surprsed to find that its sound quality came too close in sound quality to my ARC separates: a Reference 3 preamp and Ref 75SE amp. So now I'm wondering how a modern Luxman like a l-505uXii or 507uXii would compare with my ARC separates. 

Any thoughts anyone?

Hey Jerry,

 

I own a 507ux and have compared it with modern ARC 75W integrated and I really prefer the Luxman.  In extension, the Luxman makes speakers sound bigger, and the extension at the top end is better without a hint of harshness or grain.  They also have a lovely tube like midrange, but it's not at all juicy. 

 

I head the 50x line is being discontinued so right now may be a great time to find a bargain.


Best,

Before throwing the towel in on the ARCs, ensure the tubes are fresh and well-rolled. Iffy tubes can take an amp down a few pegs.

Yes , check the bias on the KT150s is on point , additional expense I appreciate however pre 1990 production S Petersburg reflector 6h30- DR make a significant upgrade in fidelity compared with the ARC supplied later production tubes
