What cables can lower my forward treble.

If you want to try a very affordable set of speaker cables that may be a benefit for the issues that you're describing, try a set of 14 AWG Micca speaker cables from Amazon for under $50.  I tried them because they got great reviews and at least one person preferred them to their Nordost speaker cables.  I didn't like them, but it was because they rolled off the highs a bit in my system.  If 2 meters  is long enough you can try a pair for about $25.  It would be a data point to potentially give you an idea for how much of a difference speaker cables could make.

I don't think he's been back since the he started the thread.

I have all Synergystic Research Foundation XL interconnects and speaker wire. I have xlr between the cary slp 05  and Pilinus 301 amp. I do have an rca interconnect between Higel Viking cd and the cary.
