I just noticed that you expressed interest in my whole system that was used for "walking" with NAD C-350 amplifier. I cannot provide pictures, mostly for practical Internet reasons and not for any secrecy. It consisted of...
SONY HAP-Z1ES, playing different kinds of music, including Hindu Love Gods. From Mahler to Kraftwerk and whatever else. Mostly at 16/44/1 AIFF and some DSD 2.8.
Interconnects, probably stock with some old equipment, but possibly also Radio Shack. Definitely nothing expensive.
NAD C-350 amplifier, bought maybe in 2001 or 2002, played a lot before, but not touched in 4 years.
Monster Cable speaker cable, about two meter each. Bought in 1994 for about $30 for a spool that supplied enough for a few people's systems and I still have a lot more. In short, cheap stuff. Finished with some cheap banana plugs, not soldered, from the Internet.
Revel Performa F208 speakers, brown, a few months old.
Screwdriver from the local hardware store, bought for ABS module change.
Salamander 5-shelf audio rack picked from the curbside garbage (furniture equivalent of a vintage Sherwood receiver). Tuned/tweaked with "Banner red" spray paint, different and inconsistent number of layers, some thinning now. Screws as tight as they could be by hand.
Red leather sofa as a sitting position.
Floor is bamboo and has a rug covering a large, maybe 80 percent, surface in between the rack and the sofa.
White piano to the side (keys moving as they always have). It says Steinway on it (mentioning as it seems to be one of the key words with your tuning). It does need tuning, the regular way.
Walls mostly uncovered, parallel, with many corners and openings, including the ceiling.
No ventilation opening of the Oneonta studio kind forcing air in the room.
Windows closed, at the time of "walking" covered with the soft (cloth) side of the blinds.
Picture would have been quicker, but would not tell the story.
Now, if you could answer a few questions, too.
