Both have pure analogue bypass (only the volume control in the signal path), so it will come down to which pre-pro's analogue stage you personally prefer.
For digital proccessing I don't know which one wins at all.
The Proceed doesn't have digital processing (unless you count their digital version of old Pro Logic decoding) while Lexicon has been at the leading edge of digital processing for the last 35 years.
For D/A conversion, from what I remember the Proceed and Lexicon use the same DACs. The Proceed runs the front L/R channels in dual-differential mode (two DACs per channel for improved signal to noise ratio). The MC-12 runs all 12 channels in dual-diff mode.
The HDMI input on the MC-12 will also come in handy when listening to hi-rez audio, whether music on SACD/DVD-A or soundtracks on HD-DVD/Blu-ray. Rather than down-convert the signal to DD or DTS, or be saddled with analogue bypass and therefore not be able to use any of your pre-pro's features, you'll be able to pour the raw PCM data into the MC-12 and treat it like any other digital signal (applying: bass management, time alignment, surround processing, room correction, etc).
Is it worth talking about 7.1, is there a lot of 7.1 recordings out there?
There are no 7.1 recordings out there, at least for consumer consumption. But the number of channels in the recording have nothing to do with the number of speakers used for playback.
7.1 pre-pros have been around for 20 years (Fosgate in 1986, Lexicon in 1988), which pre-dates consumer 5.1 recordings by a full 8 years. Obviously 7.1-speaker layouts weren't originally designed with multi-channel sources material in mind. They're intended to be used with any source material, irrespective of the number of channels.
If your seating arrangement is away from the back wall, then you should consider going to a 7.1 set-up at some point. The rear-vs-side directionality, wrap-around envelopment, and imaging stability in the surround field are not possible with only 2 surround speakers. It doesn't matter how good your surrounds are, one pair of speakers can't be in two locations simultaneously (at your sides and behind you).
Is it fair to ask which is better - Logic7 or DPLIIx ? Differences?
Of course it's fair to ask, since they are competing technologies that have the same basic functionality. In my experience, L7 sounds more exciting with 2-channel sources while PLII/PLIIx
sounds more stable (fewer artifacts). With 5.1 sources, L7 sounds more enveloping while PLIIx
sounds more directional (left vs right vs back).
The latest version of L7 also has the ability to steer content in 5.1 material the way it does for 2-channel sources: i.e., sounds that phantom image from the centre of the front soundstage are actually moved to the centre speaker for more stable imaging and greater clarity. PLII/PLIIx
doesn't have this capability.
Since L7 and PLIIx
both sound terrific to me, I gave up trying to figure out which was better. Instead I simply use both. For movie and TV sources, I use Pro Logic IIx
. For all my music listening, I use LOGIC7. The MC-12 gives you the option, so why settle on one or the other?
