re: Luxman, I've never heard the new Lux gear. When I refer to the Luxman sound as "analytical," I'm merely repeating what other, ostensibly unrelated, posters have told me. I'm ready to be convinced otherwise, but, as I'm sure you can appreciate, I don't have much to work with other than what other people are telling me. Again, no way for me to actually hear any of this gear before I buy.
Re: Silver Apex, your observations are exactly the opposite of mine. The only time I rigorously A-B'd my SA cables was when I used them to replace wiring in my phono path. They produced greater detail and a more holographic soundstage, sure, but they were less sweet and as far from tube-like as I can imagine. (Did I mention that I'm a vintage tube-roller going back 40 years? I know what tubes soudn like.)
More to the point, one reason I'm upgrading my electronics now is because the Silver Apex's "analytic" character (sorry!) actually made the flaws of my $2000 Class D amps impossible to tolerate.
I consider the difference between our experiences evidence that the only way to know what a particular cable will sound like in your system is to put it in your system. Cables are extraordinarily complex beasts and can interact with other components in the craziest ways. That's why I NEVER recommend specific cables to friends. My approach has been to learn first-hand what each mfr's "house sound" is in your system and then stick with the brand that best matches the sonic personality you need. Analysis Plus and Audioquest (strange bedfellow, I know) seem to work best for me -- at least on segments of my system that don't include Class D amplification!
