3 mtr interconnect for Cary 94L & 300B monoblocks.

I think the 'lacking in the bass'can be trace to the amp// not the wires.

I have never tried the VH Audio IC's before, but I do have a recommendation that will easily fit within your budget. I used to use Straightwire Crescendo interconnects and switched to the Virtual Image Pile Driver 18 IC's. While the Crescendo is a very respectable cable, the V.I. cables, after some burn-in time, surpassed the Crescendo's in every aspect. The V.I. cables, as compared to the Crescendo's, had better upper and lower end extension, cast a wider soundstage, had better spatial orientation, and brought out details within the music that the Crescendo's missed all together. I paid $175 for a 4 foot pair terminated with Cardas RCA plugs. For your particular length you would need to contact Al, at Virtual Image for a price quote. You can e-mail him at virtualimage@juno.com. I do know that he offers a 30 day money back policy on his standard cables, which for the interconnects is a 4 foot length, terminated with Cardas RCA's. I too use a tube preamp and amp, and absolutly love these interconnects in my system.

BTW, I don't work for/ have any attachment to Virtual Image, I'm just a very happy customer. Also, if you are considering upgrading power cables, V.I. also makes great power cables as well.
