Monster
Here's an example: I needed some cheapish, decent speaker cable that I could hide in my living room. Reluctantly and because of a lack of options, I bought a 50-foot spool of Monster XP cable at the Shark for $35. Kinda pricey for cable-by-the-foot, but I needed some. Upshot? It's pretty nice stuff. Nice teflon pipe inside, and the cable is wrapped in teflon before putting the outer jacket on. Plus, it's the most flexible, workable cable I've ever used.
Not to defend their business practices, but pretty nice stuff. Paid a little more and not too bummed about it. But the way they and Boise are slammed around here, you'd think they were killing kids.
Anything tweaky is laughed out of dodge around here. Amplifiers are thought to be immaterial to playback quality because no DBT has ever shown them to be different. CDP's are indistinguishable. Pretty much anything related to playback has little to nothing to do with sound quality, save speakers and acoustics. And, all based on theoretical ideas, not experience. And, getting back to my original point, building a system out of theory and expectation rather than ground-zero adaptation will severely limit ability to achieve the original goals, whatever they are.
And, anybody seeking reality that doesn't seriously investigate quality high-efficiency isn't seriously serious.
