Preamp-power amp interconnectors advice

I have a Nakamichi CA-7A preamp that feeds into the power amp section of a Luxman R-117 receiver. In this setup, highs and upper midrange are a bit bright while lower midrange and bass are not as strong as I would like them to be.

The CA-7A and Luxman are now connected with an Atlas Equator MK II cables that are considered “neutral”. If I use silver cables instead, the sound is very harsh and bass/lower midrange almost disappear. This leads me to suggestion that a cable that is a bit on the “dark” side, or the one with bass/lower midrange sonic signature, might be the best for this setup.

Any recommendations on such a cable with the price around $100-150 used?

Thank you,

I think you are expecting too much from the receiver; I would put the money toward a better power amp.

Yeah, why don't you get something like Nakamichi PA-5 or PA-7 power amp and then upgrade the cables?

Luxman will be replaced later with something like Nak PA-5 or Yamaha B-2 but it will stay in a system for a while. BTW it's not that bad of a receiver: 170 WPC, dual mono design except primary transformer winding, fully recapped etc.

The problem is IMHO that CA-7A is a bright preamp and this brightness should be be attenuated somehow ragrdless of what power amp I'll use.
