Any plans for a logic directed Electro-Voice Stereo-4 Matrix decoder?
(perhaps a modification of the QS decoding system)

Hi Quadwreck
I accept your challenge.........all we need is a group order for US$100,000 and we will deliver them wrapped up in a blue ribbon in a pretty shinny box within 9 months
Form an orderly que here..............................

The anticipation is almost over - received the shipping information for my SM SQ Vinyl Edition :banana:
Hello schultz1010.The other thing that was needed was to adjust the input levels to the A/D converter - the Sony had a low output level where the SM is more "normal". Most A/D convertedr lack analog preamp stages - but luckily I'd front ended the Apogee Digital Quartet (http://www.soundonsound.com/sos/nov12/articles/apogee-quartet.htm) with a unbalanced/balanced level converter that has trim/gain (+/- 12dB) capability http://tascam.com/product/la-40mkiii/

Hello schultz1010.
By ear?
Nice toys, schultz!!!No, I used the meters on the Apogee Quartet and the app they offer to control/run the Quartet - called "Maestro" . http://www.apogeedigital.com/products/maestro
Nice toys, schultz!!!
Is there a step in your procedure that optimizes the AD conversion in the Involve unit, by inputting the highest level that won't overload the ADC?
Thanks for the compliment - serious playing requires serious toys
There's no A/D conversion in the Involve unit itself,
The chain is:
Turntable -> Phono Stage -> Involve SM -> Tascam Level Converter -> Quartet A/D converter
The only place that has any level adjustment is in the Tascam. Once set I plan no further changes to the levels unless I see/hear clipping. I prefer to leave lots of headroom in the A/D process. I digitize using a 24bit sample size and that gives *lots* of room for adjustment later without impacting the quality. If 2 or 3dB of gain is needed it's better, I think, to do that in the digital domain instead of tweeting the levels for each recording. It's best I think to minimize the feeling that constantly adjusting/fiddling optimizes/improves anything (but that's just one person's (mine) opinion) - as the saying goes "better is the enemy of good enough"
the phono stage is a Phono Box S dedicated to Quad http://www.project-audio.com/main.php?prod=phonoboxs - like the Involve SM, a cute little box
Err
Actually the SM has an internal A/D
