Referring back to your JBL AV1 comment (I have an SDP-5, essentially the same product), Harman's last "new' Lexicon was the MV-5 (JBL AV2, of which I have two) which introduced HDMI, 7.1 analog inputs, USB, and, okay, The Bridge.
I really wanted 7.1 analog in, which the SDP-5 didn't have, and neither did the SDP-40. That alone was enough for me to move from the SDP-5 to the AV2.
Since the HDMI was stuck at 1.1 in the AV2 and limited to 1080i output, that wasn't too compelling for video. I prefer HDMI straight to the PJ anyhow.
The fact that it accepted HDMI audio in but could not decode HD audio was kind of defeating, too, though obviously any decent Bluray player could do that.
The USB is potentially cool, unless you're a Mac owner. So, hey, no cigar there either.
I like sticking my iPod in The Bridge and controlling it from afar, but the UI is weak, and as I recall you can't get the digital stream from it, only the analog one.
There's also a mic and unnamed auto set up, but I took a different calibration route.
I do like the way the unit "sounds."
All of that is to say, since the MC-20 is dead, what are the odds that a retreat to MV-5/AV2 territory could yield a path forward for Lexicon. I know the units were derided for being Chinese and HK AVRs without amps, but I find the unit pretty satisfying, given its several shortcomings. Eliminate the unneeded video stuff, beef up the audio section, fix the freaking USB and iPod stuff, offer a balanced model, figure out if the customers that will actually buy it want auto-EQ or will want a calibrator anyway, put a nice billet face on it...
This is why I'm a consumer and not a designer or an engineer.
