Headshrinker,
This is the first time I've used the "quote" function, so I hope it works out.
Yes, I have compared what I use with Audioquest, MIT, Kimber, Cardas, Tara Labs, Transparent Audio, and Tributaries (relatively inexpensive line, this last product).
I had no ill experience with any of the products I've listed, but when making the change to "broadcast/professional/industry-standard type" cables, my personal and anecdotal experience is that what I heard coming out of the system was more "true" to the source. A lousy CD would sound revealingly so, and a finely recorded one would sound especially so.
The Belden 1313A speaker cable seemed to be most "noticeable" to me during comparison with Audioquest/Transparent Audio/Kimber wire I'd used in the past. Sounds like cymbals (whether in popular or Classical music--think Stravinsky's Firebird Suite) resembled more what I might hear in an actual concert (with obvious acknowledgement to the "This is the not a pipe" thread elsewhere in this forum). The bass seemed more "precise"/"punchy", too.
The differences weren't extraordinary or magical, but I *did* notice them. To some folks, that *would* extraordinary or magical. I just say they were noticeable and leave it at that.
I've not tried different power cords. I use what Bryston shipped with the units I have. Elizabeth has mentioned Pangea power cords in other threads, and I'm curious to try them out sometime. I don't know whether I'd notice a difference, but the cords are attractive as well as relatively inexpensive.
Ilkatze,
I'm curious. Did you ever have the opportunity to compare your Blue Jeans Cabling with any of the audio cable "boutique" brands (Audioquest, Kimber, Harmonic Technology, Nordost, Transparent, XLO..ect)?
I was just looking at cable prices on Blue Jeans yesterday. Wiring up separates with balanced Belden 1800F is quite reasonable. Especially in my Bryston system, almost every cable change (IC, coaxial, power cord) makes some audible difference.
