Good Ole Kimber Kable 8 or 12 TC is surprisingly great at fixing this kind of issue. I'm not a fan of cables with boxes on them either. Cables are tone controls, its important to find ones that make the changes you like.
Speaker Cable Recommendation
I'm wondering if someone could recommend a pair of speaker cables. I have looked at Nordost entry level, but they may be too thin for my system. Looking for cables that may add some "weight" to the following system.
Decware 300b tube amp (8watts), Klipsch Forte IV, Holo May Dac, PS Audio BHK Pre with 12AU7 input tubes. My room is 20X12, not treated, vaulted ceiling, fair amount of glass. Not a great room :) In the $1,000.00 range
Thanks, Mark
