I've heard the Mogami, they are just ok...nothing special. I enjoyed Analysis Plus Oval One just as much or more in my system. Audiolabyrinth is correct, the audiophiles need better cable. He's probably correct about why too. But what it boils down to for me is that once I had heard what some of the better quality cable do for an audio system, there was no going back to $100 "studio standard" ic cable.
Also, I have to agree with Zd542 that yes, cables are system dependent. So...if you want to know what cables can do for your system, simply try different cables at the top of your price range and then trust your ears. Most will find cabling with a sonic signature that is pleasing that presents the music the way they like it to be and for reasonable cost. I don't know what the big deal is? If God forbid you do not find any "high dollar" cable that you like, you can resell it easily in the used market!
This thread brings to mind a quote from author Robert M. Pirsig
"Quality is a direct experience independent of and prior to intellectual abstractions".
Robert M. Pirsig
So maybe just use an open mind, several hundred bucks or more, and hours of QUALITY listening time to select your favorite cables! If all else fails...ask Audiolabyrinth and he will tell you what you should get! hehe
Oh yeah, one more Pirsig quote for the cable haters:
~ "The absence of quality is the essence of squareness!"
