XLR recomendation

For value ,quality look at the Wireworld Eclipse there is many excellent attributes 

and one huge factor many lesser cables don’t have is pure silver over solid copper connectors. 6.9s pure Copper ,patented lowest dielectric resistance, and their geometry greatly reduces eddy currents ,the speaker cable is a very substantial awg

and connectors are screw on if you want to chance bananas or spades ,

and can be ordered with internal bywire if needed , XLR the same quality.

@carlsbad2 Meant to say that the Heritage is a fully balanced integrated amp. It has both balanced and SE.  Because it’s balanced it’s been suggested to use XLR rather than RCA with DAVE. Though I’m enjoying my. Syn Res RCA’s. Will be interesting to A/B RCA and XLR eventually with DAVE. 

AZ Absolute Copper (used them for few years) is a good recommendation if you are looking for warmer, thicker sound with big bass (could sound bloated depending on the rest of the system and room). I moved on to Nordost Tyr 2. Better balanced top to bottom, slightly more resolution, tighter bass, better separation and bigger soundstage. Again, it’s all system and listening preference dependent.

I had a very good result going from Zavfino's Fusion RCA to Fusion XLR from my phono stage to hybrid integrated. Under $400 delivered.

Using the same cable allowed me to really hear the difference between single-ended and balanced, which was huge.

FWIW, they only sell direct and have skinny margins, so my guess is these would be 3-4 times the cost if they went through normal distributor-to-retailer channels. 

(If money is no object then you could look at the Silver Dart XLRs for around $1,600)
