The SB-G90 (Grand Class Model) I have had the opportunity to listen to and I do own the Premium Class SB-C700 Speakers.
The x-over components (SB-C700) are good quality high spec parts-a lot goes into the neo Technics Gear.
Solid Cabinets / Finish.
The SB-G90 design has an innovative internal baffle mount for the drivers
which Technics made the effort to use.

Then make a decision on just how good ...
