I think there are many posts about the Grand Class on here for your reference.
I own the Grand Class. I spent more than my budget by about $2k, but I have not a single regret. In addition to fantastic sound, the machine is so well built. I think it might be hard to best the R&D and economy of scale of a committed company like Technics.
The value of these tables is extraordinary. There are some who have understandable difficulty in getting past the styling, which they equate with the old 1200s. The new R, G, and GAE may be cousins of the old 1200s in some ways, but they are different animals.
I pair mine with an AudioTechnica ART-9 cartridge and a Manley Chinook phonostage. The overall sonics best my digital setup, which runs a Stereophile Class A DAC. There is nothing I can fault on the GAE.
