After listening to Circle Surround at the audio store.... typcially the set-up to ascertain the quality of surround output was lame.... excess ambient noise, poor speaker placement, etc. I did enjoy the "sound" of the SRS Circle Surround output of synthesized surround from a stereo source.
Since it will likely be 3 years or more before I can think about buying a new receiver with all the goodies... Pro Logic 2 or whatever is out in the future, Matrix 6, etc etc etc and since my main desire with quad hardware is synthezing surround from stereo sources, I kept an eye on eBay waiting for a free-standing Circle Surround decoder to appear.
There IS a new format from SRS... a Circle Surround 2 or whatever they call it, but, I don't think it's being placed in receivers or decoders yet and it will likely be pricey so.... when I found a low-priced eBay offering I jumped on it and..... won!!!! Wheeeee!!!!!!
I have never been burned on eBay so am assuming that in a week or two a new-in-the-box Circle Surround device will be plugged into the system. Will submit a review of the output, etc at a later date.
Anyone with experience with Circle Surround is invited to submit their aural experience with the output of this unit.
