Though it has been quite awhile since I wrote a response on this thread, I nevertheless feel it appropriate to write about my experience with Star Sound. Due to audio room redesign and ever increasing job-related intrusions, it has been only recently that I have had the opportunity to audition Sistrum in my system.
The speaker stands were the first items installed, and the improvement was highly beneficial. There was definitely less smearing and better focus with the stands. The bottom end tightened up but not at the expense of the natural decay and expansion (as opposed to bloat). Certainly, this was the the best $370 upgrade I've ever had in my system.
Next, I used the Sistrum amp stands for my new WAVAC 833. "Wow" is not overstating my reaction. As great as the WAVAC 833 monos are, the stands took them a step higher. Incredible dynamics with concrete-breaking low-end extension were the first things I noticed. Yet, at the same time I found a less stressful sound, particularly at higher SPL. Given the performance of the stands I was previously using, I was not prepared for the improvement the Sistrum amp stands provided in my system.
I'll also add that for you DIYers out there, the high Cu content / lead-free solder available from Star Sound is extremely good. It is a bit of a pain to use since it requires a high temp iron and the use of liquid/paste flux, but the results I obtained speak for themselves. I've used many different solders over the years, and this is my new reference for sonic performance.
I've just ordered a long run of the Sonoran IC from Robert, and I'll be very interested in comparing them to my past and current references. I'll report my experience with them at a later date.
It has been a distinct pleasure experiencing the highly effective (and visually beautiful) Sistrum products. I highly recommend them for anyone considering similar products. I would guess that their "satisfaction guarantee" is rarely exercised.
Enjoy!
