Should I change speaker cables?


I am currently using Harmonic Tech Pro9+ but at time I feel the sound may be a little on the warm side and makes things congested with bass heavy materials. Although I don't know if it's my sytem or the cables but I am think of buying a pair of Nordost Blue Heaven to try out.

System consists of Living Voice Avatar, VTL Deluxe Mono 120, Musical Fidelity Pre24 and HT Pro Silway II.

Pro 9+ are fine cables. I found, however, that the skinny little Audience AU-24 cables outperformed them in every aspect. You may want to try these and see how they work for you.
Don't buy anything. Call The Cable Co. and get a loaner from almost any brand you can name and try them out for a week. It's the only way to go. Call 1-800-Fatwyre. I do not represent them, but have dealt with them for years.
I second Elinor's recommendation, but would add that their advice as to which cables to use has been outstanding too!
