I'm a skeptic - 110%, no question about it. And I've watched this poor horse get beaten here numerous times. But I'm going to reconsider this topic, and say there might actually be something to it.
Today, I replaced the 12 foot run of RadioShack RCAs that connect my CD player to my receiver with a much nicer 15 foot set I just received from Amazon.
From these:
To these:
Nothing too incredibly fancy or expensive, but nicer nonetheless.
There is no doubt in my mind that there's a difference in sound for the better. My first play was one of my favorite CDs which I've memorized over the last 20 years or so - I know every letter, note, and nuance: Jerry Rivera's - Lo Nuevo y Lo Mejor.
A brighter, more engaging soundstage, lively, and even a little more pronounced and tighter bass.
By the time I got to track 11, No Hieras Mi Vida, (probably the best track on the album), I had to sit down and just absorb how good it actually sounded.
This was absolutely and totally unanticipated. I had only bought these cables because they were just a bit longer than the RS, which would make that run around the corner a little cleaner looking instead of cutting across the floor under the chair.
I already have a 3ft set of the same brand that I use to connect my laptop's external sound card to the stereo, and I just liked the quality of the connectors (those plugs feel like the ceramic bezel of the old DiaStar watches) - besides that, though, I never really gave them much thought.
But there was no mistaking how much better these made the sound from the Teac to the Yamaha.
Now, one could reasonably argue that I was in a good mood because the electric grid had just finally been restored here in PR this afternoon after our total, island-wide blackout on Wednesday.
One could also argue that of course it sounded better since I've been only listening to a cacophony of generators in the neighborhood for the last 3 days.
I can't argue against either. Both statements have reasonable merit.
But, every CD I've played has presented similar sonic improvements - even using the Teac's USB port to stream from my phone.
Count me in. There just might be something to nicer cables improving the final sound.
