I located my SMv2 around knee level in my rack ( just was the only spotI had for it), and all the knobs block out the LED's which I love anyway.
Request for SMv3:
(1974-12) SQ Stereo Enhancement [CBS Labs] | QuadraphonicQuad
Please consider adding SQ SE mode 180 and mode 270 to the SQ decoding part of the (planned) SMv3.
Kirk Bayne
The Surround Master already has 180 stereo enhancement as integral to the QS/Involve decoding. This is when left only stereo input equals center left where left front & rear are equal level & right front & rear are silent. It was this way in Sansui gear or by Involve, it's just the way QS works.
What would be benefit is 270 deg wrap around effect. In QS mode this is accomplished in the easiest of ways by simple opposite phase blending at -7.7 dB between the input chs. I accomplish this with an external front end to the SM. It can make a huge imrovement. Much easier than SQ enhancement.
The quality of the source signal is more critical on SQHey Fred!
I might refer you to a previous post of mine where I did some testing on the SMv2 & directly addressed the question of center front to back leakage in the SQ mode:

For a quick referral center front is the same in either QS or SQ encoding. In decoding on the SM there's about -50dB speration to the rear in QS & in SQ about -16dB. Clearly there's a difference there but the -16dB is plenty much to lock the focus up front.
I never pass up the chance to mention the quality of input signal to the SM is of high importance. We tend to take it for granted that our LP records are balanced to a gnats eye lash, that our pre-amps are really "neutral" when knobs set to the 12:00 position, etc and sometimes they are not. As an example I suggest, if you can, apply a true mono signal to the SM, listen to only the rear chs & adjust input balance to the SM left & right a bit. You'll find at one point the center front bleed through will be markedly reduced.
Chucky, when are you going to finalize the SM V3?
Still waiting for the boards to arrive from China, only found out 2 days ago that there was a delay in payment that slowed the train down.....DOH!
NO BATS FOR YOU!Will it come with Wutan Bat Soup?
Don't believe they are; that's the big issue and hopefully the new preamp will provide some relief, albeit at a cost. I'm using legacy Sansui QRX-8001 for the SMv2.Ok, so how are you guys hooking this up to a newer receiver that does not have 5.1 analog inputs ? or are you only connecting this to legacy equipment?
I have a Lexicon RV-9
I bought an AV Amp with 5.1 analogue inputs, a Pioneer SC-LX86 in 2013 (was about £2000). Unfortunately they are becoming rarer and most that are available are 'top of the range' or close to, so cheapest I have seen now is the Marantz SR7015 at around £1500, another is the Denon AVC-X8500H at about £3000, and I think Yamaha has a couple with 5.1/7.1 analogue inputs.Ok, so how are you guys hooking this up to a newer receiver that does not have 5.1 analog inputs ? or are you only connecting this to legacy equipment?

Let's not forget also, that there are still tons of just slightly older AVRs with 5.1-7.1 analog inputs; that sell for very little (and all electronics are prone to a myriad of failures.)I bought an AV Amp with 5.1 analogue inputs, a Pioneer SC-LX86 in 2013 (was about £2000).
