|As for the crossfeed, it's like an unpredicatible tone control, a no-no for hi-fidelity. Nevertheless, if you are not too picky about sound, it is a decent bridge between headphone listening and speaker listening.
You guys sounding like the "purist" extremists here. I take a bit of offense at the idea that crossfeed is "decent" if "you are not too picky about sound."
Hell, if I wasn't picky about sound, I wouldn't be here
Temple, have you ever even heard the Max? There's little "unpredictable" about its crossfeed circuit. While the cheaper electronics in something like the TA make its crossfeed affect the sound noticeably, the Max is a whole 'nother ballgame. I would suggest that before people go bashing crossfeed, they actually try out one of the "reference" level amps that use it.
Vertigo, when you talk about the HeadRoom crossfeed circuit, to which amp are you referring? As I think Jude will agree, the Max knocks off far less of the high end than the Airhead does, and the filter sounds anything but unnatural. I've done lots of fiddling here trying to test out different combinations of crossfeed/no crossfeed and no/some/more high boosts, and I gotta say that crossfeed sounds more realistic and more accurate than no crossfeed on almost every recording I used.
And the whole notion that tone controls are a "no-no" for hi-fi is a total crock. Tone controls/equalizers that are used carefully can compensate for things like poor room acoustics. The problem with "audiophiles" is when they get so caught up in the lingo and the myths that they forget we're talking about audio waves and human hearing. I've been guilty of this myself many times, to be quite honest.
