Year ago (late 90's) when I was in Akihabara I found an oasis of a store in the middle of the tech junk.
It had a love affair with large speakers like JVC's and Tannoy's, and big amps like Accuphase, Kerell, and Levinson; lots of other brands, though, and they had a display not too far off from what you posted (no keyboards/synth's, though).
Two regrets: I only wish I was able to communicate with the proprietor better....and they had a wonderful selection of 3 Blind Mice CD's, and I was stupid not to get any at the time....
