Yes, there are really good cables for little $ out there..personally, I love, love, love Groneberg's....keep in mind that all products have them internally, and thus, it would be a perfect inductance / impedance / tonality match with our gear...HOWEVER, as always, synergy trumps everything (and so does personal taste, obviously)...regardless, as long as the cables are copper based, you should be able to get rich, warm timbres with our stuff....
now, as for your question and budget:
5 x Groneberg Series III interconnects are $ 275.
