Kimber Hero. 0.5 meter XLR always in stock at Music Direct and well within your $300 ceiling.
I recently rewired my system with Cardas Clear Sky as an upgrade from Hero, but I happily used Hero in my system for a good three years and I still keep a box of Hero ICs in my closet as backups.
Great choice on the Audio Envy cables IMO. I’ve been using their balanced, se and speaker cables for about 6 months and I couldn’t be happier. I’ve quit looking for cable upgrades. You also have 45 days to evaluate them which makes them a no brainer to try. Hope they work well in your system.
Well I’ve had the O’nestian 4:4 XLR interconnects in my system for approx. 2 weeks now.
They aren’t finished “settling-in” yet; but already, I am loving what I’m hearing!
These are excellent cables! Great value also!
