I purchased the G91A together with a DSP5200HC and is now enjoying the TRI-Field life. Interesting after 25 years of 2-ch stereo.
I am using a pair of Philips DSS—930 for back-sur. (an interesting DSP-speaker very much like a DSP5000). The back-side being that I am not able to run Meridian COM. with them.
I have been offer a pair of DSP6000(24/96) at a very good price. I am not able to test them before purchase. Are they a complete over kill?
