I've found the most important thing with any setup is room-speaker coupling. In my medium size room, I found it relatively easy to get a good setup with my S5 Mk2's using the basic Cardas room setup guide. Being a sealed box design, they can be placed relatively close to the front wall which is helpful in a living/dining situation. And the diamond-coated BE tweeters have better off-axis response compared to the previous generation, hence I found they required less toe-in than my old S5 Mk1's.Having all the time and making all the effort in a home set-up is different. But yes, those are not speakers that you can simply drop in a room and expect instant miracles from.
From my POV, the main culprit in most of Magico's rooms at the MOC this year was the accompanying equipment. Personally I would've loved to have paired the M2's with the new Vitus SIA-030, UHA Ultima 4 tape deck, Tech Das AF3 Premium, Gigawatt Evo conditioner & Stillpoints Aperture II panels. I think that would've nailed plenty of bums on seats. That said, I think this side discussion has probably gone on long enough & the point re: the thread title is well made. Back to normal programming..
