I am just one opinion BUT

Supra classic speaker wire is the strangest wire experience I have ever had, cloudy, muffed, detail smearing,
the client who bought it from me when i said I was trashing it asked me to come get it off his rig later,
I take note one reviewer said it was such a incredible wire, "it was still breaking in two years later, just always getting better" :wtf:I could not get it to break in, nor could my client, who i warned not to mess with it.
I really did not want to write this above, cause i avoid the ""
I am a snoot audiophile anti-music lover, I am more holy then god nit picking anal I will never be happy RUT folks"" at all costs, but that madisound even sells this stuff, scared me off from ever experimenting with what they might think a cross over is, many of which are made by pros outside the shop, so I MAY
( Prey, HOPE) VERY WELL BE WRONG" and I wholly completely recognize they sell some of the best speakers in the world, simply best speakers in the world.
That are often paper by the way

I love paper

it cost me hundreds of dollars in mail order experiments to say the following,
I have never found a tin'ed speaker wire that I could live with, it just sounded surreal, but in opposition to that line of thought,,,The only solder covered RCA wire I have ever heard work is a C2G Velocity RCA IC at not more then 3 ft. the teflon foam dielectric version, just 1 set between a CD player and pre has a astounding ability to warm and slow a CD player into musicality, and remove useless over detailing Bright schlock SHOCK syndrome.
I cut the RCA's off, install better,
cover with braided sleeving and sell for $100.00, often using it to rescue a Bright AS Schik system.
I don't know what they did different then the supra, but the tin finish on the "Stranded" C2G is like a very extremely brite chrome, it looks nothing even like tined wire.
their solid one wire (non optic) digital cable sucks for audio, ringing Etc.
One mans poison ETC. this link is for the 1.5 ft
