Does such a cable exist- sweet, lush, detailed & dynamic?

Of wire I’ve heard, Audio Note silver wire comes closest to what you want.  Snake River is also good.

I'll second the mention of Audio Note, but with a big warning about fakes. They are everywhere. Probably a 10 to 1 ratio of counterfeit versus real at this point. I would only buy from a rock solid authorized distributor at full price, and even then I'd be nervous.

Very happy with my Veritas Cables so far, they also seem to fit your requirements for a very reasonable price. I'm buying more this weekend with the upcoming sale.

A Wire used in a Cable known as D.U.C.C is able to present with a hint of a Tone of Richness and preserve all the micro details as good as and other signal path wire.

Cables readily available using this wire type are found from Acrolink and Luxman.

Note: D.U.C.C Manufacturer Mitsubishi has recently announced a newer version of this wire type is to be made available.

How long before that is seen as  a purchasable material is a unknown.      

I may get disagreed with but I have been a big Cardas fan for 30 years.  I now use Cardas Clear Reflection interconnects from DAC (K-01XDSE) to pre (LA4) & from pre to amp (XA25 at this time), though not for the TT->phono stage.

They seem to be a great balance, my system is VERY neutral and those cables give a hint of warmth without (IMHO) hiding anything.
