Need your help on SPEAKER CABLE...

I agree about trying various cables to see what works. I would suggest some used Cardis, the Golden Hex or Hex C would provide the tonal balance and dynamics you are looking for with your equipment. Golden Hex should be near your budget, and may sold if they are not for you. If you are going through the Cable Company, you should audition the Purist Audio Elementa. These are excellent and are priced at $300.00 full retail.

The Purist is extremely low distortion, and has perhaps the most effective shield against vibration, RF and EMI. It is difficult to know if what Purist offers in these specific areas would be of benefit. Elementa is also extremely phase accurate, allowing objects within the soundstage to retain their own space. These spatial cues are what determine the holographic effect in imaging, and are sometime lost with cables that cost many times more.
