Hey, its all just advice based on my years of experience of trial and error. I certainly wouldn't want to come across as a know it all when I offer advice.
I may have offended with sensitive cable difference talk it seems. A blanket amount of $200 doesn't mean much if a model can't back it up so I should have been specific. A $200 used Red Dawn or Maple Audio Works Ambiance will clear up any thoughts on a cheap signal passer including the Rad Shack if the other equipment is worthy of the exposure. I easily hear a difference for the better with Linn Aktiv gear which is very revealing to begin with, the Red Dawn reveals more, period, or I would have saved my money. I also have Rad Shack and Linn cables for less demanding applications. I agree they are decent for cheap.
If a person likes a cheap cable just as much then its good, save the money. The music is what matters. I know what I hear and thats not for debate. Each person needs to decide, we don't have to be rude.
I didn't think McCormack was in the same league as Rotel and Parasound, plus I have never heard them so I left them out of my few inexpensive examples. There are many others that could be better than this or that for arguments sake but I was just offering advice on gear I have actually heard. I'd venture to guess the Bryston could be as or more enjoyable just the same. Again, I am only advising based on experience having owned many combinations including the Primare A30.1, Plinius 8150i, Bryston B60, Parasound HCA1200II, Rotel RB1080. 980, RC995, Belles 150A, various preamps. Now to my Linn Aktiv gear, which for musicality, I have not heard better but I am sure it exists.
Great feedback - kinda!
