Tel Wire Cord experiences?

Yes they do seem to punch well above there weight class but they are somewhat utilitarian looking.

Lotusdriver,
Yes, the TelWire is somewhat utilitarian looking compared to the huge anaconda-sized ones out there. From what I understand, the cord uses only the necessary amount of shielding around the conductors in order to maximize the purity of the AC signal passing through it, and still prevent EMI/RFI from affecting its performance. The maker probably could have fed the conductors through a large tube to give it the fat snake-like appearance of other cords, but for his own reasons chose not to do that. I do know that there are some proprietary things which have been done to the cord that you can't see externally.

I put a new TelWire standard on my EMM CDSA SE
and it is very nice.
It seems to produce just the right bit of warmth that complements the EMM but does not mask anything or cause any loss-of-control in the wonderfully tight/transparent EMM bass.
I had been using a TG SLVR but it produced some ringing upper midrange notes on some older popular CDS. The Telwire maintains the nice definition of instruments and vocals of the SLVR but keeps things from going over-the-top and prevents piercing digital artifacts from hurting my ears. It may have a slight "calming" coloration, but it is very satisfying, even addictive. I would call it reminiscent of a tube sound, meaning transparent and natural with all the nasty, painful digital overtones deftly handled.
I had tried some other powercords but they would muddy-up/loosen the bass unacceptably or make things too clear/tipped-up/clean for my tastes (I hate listening fatigue). So I'm keeping the Telwire and think it is a relative (ok BIG) bargain for this level of refinement.
