I own a Sistrum rack and am very satisfied; in fact I have never been more impressed with an accessory, as they are beautiful to look at, completely neutral, and natural sounding.
Having gone through torture while experimenting with countless racks, and isolation device configurations over the past two years; which included names like: Grandprix, Polycrystal, Aurio pros, Still Points, Walker audio. Etc, etc. - not to mention endless
A-B-ing with all different types of combinations - I realized that this was no longer fun anymore, as I was becoming insatiable and had begun to lose my compass north.
After talking with the - I believe - highly ethical and knowledgeable guys at Star Sound, I ordered a 36" rack, and have never looked back. Again-nice looking, large sound stage- opened up the sound dramatically, better dynamics, tighter bass, while remaining completely neutral and natural sounding; I could also turn my volume up 15-20% + higher on most CDs', as the background was so much quieter. Last but not least: I sleep better now not having to worry about tweeks that "might of been"..
Very happy with their racks, I decided to try their Sonora cable, having experimented extensively with Shunyata (Anaconda), and Virtual Dynamics (Nite series) power cords and interconnects - all with much of the same above frustration..Star Sound prevailed once more, while re-enforcing the above positive results I had with the rack - a no-brainer at about 1/2 of the price.
There appears to be definite synergy achieved when using their equipment together.
Sorry to go on about Star Sound products, but I feel that they don't always get the credit they deserve on Audigon. Considering that they are aurguably one of the highest technology based audio manufacturers out there - that also happen to sound good as well.
Lastly: Their new Caravelle Speakers of course I had to try a pair.. and all the great things that Warren expressed have been basically my experience too, except that I havent received their Sistrum proprietary stands yet (a critical component).., and have instead been using my cheap lead-filled Target stands for now, so a little premature to comment. Though I will say that even without proper brake-in, and with the wrong stands, they were far superior to my Verity Fidelios which are about twice the price.
These guys, and their technology at Star Sound - in my opinion are for real.
Associated equipment: Meitner front end and Jadis integrated amp.
