what to buy under $500 bi wire spkr cable

The metal dome tweeter in these have a resonance shown here right above 20 kHz. A lot of people are sensitive to this. This may be a large contributing factor.

I agree with Tmsorosk, I don't think this is a cable problem. PSB Stratus Gold's are excellent speakers with great low-end extension. From your description of the sound, it seems as if your amp doesn't have a firm enough grip on the speakers.

I would work there, and then mess with cables only when you're close to the sound you're looking for.
