Which speaker cable?

I can't speak for your system and synergy, but there is a pair of used Luminous Renaissance for $85 or so and another for $150ish (new price is $200-$300, I think). They are extrememly fairly priced (considering how ridiculous cable prices can be) and a deal at full retail price, but the used price is amazing. I replaced a pair of Cardas Golden Cross ($1200 used at the time) with the Renaissance and felt they were better in almost every way. They may have been a bit more forward in the upper mids than the Cardas, but they improved on the overall resolution by a huge amount and the bass struck me as more realistic and defined. I preferred the Audience AU24 and the TG Audio wire to the Renaissance, but both are many times the price.

I would try a variety of suggested wires and see which you prefer. There can be quite a huge difference between brands, and all will likely react to your system in different ways. Good luck...

When i was running B&W 801 matrix i was using Monster M1 or M1000 can't remember which.
Upgraded to Audiotruth Argent bi-wires ( midnight on lows )and noticed quite an improvement in overall performence. Much better detail,quicker and tighter bass response.

4cranch, Here is a short, but insightful, perspective on audio cable. I find it an interesting read. It explains some of the basics of design and materials usage. Bottom line, they are a great sounding value.

Happy reading.

Audioquest sterling- if you can afford it. Nothing compares

The cheap and good working solution:
Go to home depot and get a roll of 100 ft 16 AWG sold core copper ( $8.20 ) and make twisted pair for each + and -.
This will give you 13 AWG and it will be much cleaner and tighter sound than the monster cable.
