What cables for luxman

I have the Luxman 550aII and D-05 and am using blue jeans xlr for $50.00 .
I tried siltech 330i and did not notice much difference except for a some glare on trumpet sounds with the siltech, maybe they were not burned in.

I have the Luxman D 05 and 550A II.
I use 2.5 m Luxman JPX 10000 CL XLR and Morrow SP6 Ref SC.
I use the Luxman power cords. Noticeable benefit.
The Luxman XLR is clearly superior to my Morrow MA6 1m RCA IC's.
XLR has no inherent advantage over RCA over short distances unless you have a "noisy" electrical environment - which nearly all domestic situations do not. Having said that, XLR is useful in eliminating ground loops.
The Morrow SC is a capable speaker cable but better suited to some valve amps I have tried it with.
The search continues...Goertz next.
