You don't say what your system means to you and what your future intentions are, so I am going to throw this out at you. If I'm completely off the mark or out of line, I apologize.
I had an experience where a tube in my preamp went out and took one of my monoblocks along with it. Not being familiar with tube equipment, I switched the right and left interconnect and took out the other monoblock.
I had to send the preamp and monoblocks in for servicing. During those following few weeks I pulled my old B&K preamp and amp out of the closet and put them in my system.
I hooked them up with the Stealth Indra interconnects that I was using and couldn't believe how good my system sounded!
My point is this, given the state of the economy right now and the deals available on Audiogon. If you intend to upgrade your system in the future, now might be the perfect time to buy the highest quality interconnects that you can comfortably afford.
This will not only make your system sound much better now, but they will support your system as it grows in the future. I personally found out that with the very expensive Stealth Indras, they brought my B&K components and system to a level where, had I not known how much better the high-end preamp and monoblocks were, I could have easily lived with the B&K system.
One on-going topic of differences of opinions here on Audiogon is cabling and other tweaks. I hate to see that, because of my own personal experiences.
I honestly believe that the components these days are a lot better than most suspect. The manufacturers are trying to hit certain price points in the markerplace, and can't afford to stick a good pair of interconnects, power cord and footers in the whole package and maintain the lower price.
But when you read about upgrades, where do they usually start? Beefing up the power supply is normally the first thing that you see. Where the electronics themselves are good, their full potential isn't being realized due in part to smaller power supplies and power cord, smaller and more restrictive interconnects and even non-vibration dealing footers.
Give components a chance and I believe that we'll all see that they're quite a bit better than we thought they were when we first pulled them out of the box, set them on a shelf and plugged them in.
