Favorite sounding interconnects?

I have tried many interconnects including Nordost SPM and Cardas...but for single ended RCA my absolute favorites are Pure Note Signature. I haven't heard them myself yet, but I have been told that the new Pure Note Epsilons are even better (if that is possible).

I agree with Craig regarding the Synergistic rec. I'm hardly golden-eared but have found the Resolution Reference Phase II to be quite neutral. I later noted with interest that Stereophile agrees with my neutrality experiences. In my search for system synergy, a number of components have come & gone at my house, but these interconnects remain. They are 1 meter lengths with RCA ends; 2 meter length didn't sound quite as good though. I even bought a couple pair of Looking Glass-II to use for tuner & aux. functions. Adding the active shielding power supply (Master Control Center II) greatly enhanced staging & even bettered bass control a noticable amount. It sounds best when powered by a (guess what) Synergistic Designers Reference Squared AC cord, as does my Accuphase preamp, so the synergy question may have some vaildity although I use some high-$ MIT speaker cables with it all.
CD is an EAD Ultradisc 2000, P.A.'s are McCormack DNA-1, Ayre V3, Perreaux 350.
I think that covers all of your questions. The Synergistic interconnetcs don't 'blow you away' they just get 'out of the way' which is what impresses me.
Now what are YOUR interconnect experiences, Mr. Wentereprises?

having tried many different brands of interconnects,cardas,harmonic tech,acoustic zen,audio tekne,synergistic reference,purist audio and most recently xlo limited edition and nordost 'valhallas the last 2 are defininely in a small group of interconnects that can be labled 'the best money can buy'.they truly allow the signal to be presented unaltered or colored.i use the xlos and valhallas( and valhalla speaker cables ) with my current system of 2-aloia amps,aloia preamp,scd-1,dodson 217mkIId dac and piega p10 speakers (biamped).the cable company will,for a fee, allow you to try these and other cables in your system.it will allow you to see how good your system can sound.

Try Highwire cables, they will make you smile and save your pocket book.

47 Labs. This cable is amazing, it blew away everything I compared it to (once broken in) and shattered all my ideas about what cable was suppose to look like too. There has been a long ongoing discussion about it elsewhere on Audiogon Forum. You have to assemble it yourself (you just get a spool of cable and ends) but for the amount of wire you get, one can safely say this stuff is relatively cheap too.
