What is the best power cable under $200.00 retail?

TimePortal Audio Silver Reference, uses 6N silver only wire 18AMP, very thin multi-stranded, and an aluminium shield plus a furher silver plated copper shield. IEGO Rhodium plated Furukawa 99.99% burnished copper. Available from the internet US$175.00 including shipping. Unbelievable performance in my system, speed, timing, purity and headphone like detail. Includes a further ferrite? box to clean up the sound of the mains. I bought it this week, so want to let the audio community know. These may well retail much higher expensive in the US. Note I am an audiophile and not affiliated with them in any way.

I agree w/ Macdad that upgrading source or amp is way to go; IF you have the $$$.

In my system, upgrading amp, pre, DAC or speakers to something that would make appreciable improvement is not affordable. However, for under $100 I can get a little improvment by replacing stock PCs with PCs from Signal, Element, Zebra or some of the other companies mentioned in this thread.

Check out our Power Cords, they are an exceptional deal. We use real WattGate Connectors and we are having a 15% off sale on all cable @ www.pnfaudio.com

USE COUPON CODE- Audiogon

I nominate the PS Audio Prelude, or whatever is the current equivalent iteration. I'm using one with my integrated amp, so I think it would be a good match with your Cambridge.

Vintage Audio Labs (ebay) Nice Rhodium ends and tight fit.
