Sound Application line conditioner experience?

I did have an earlier model (plain X,I think) Sold that puppy,pronto.(( It did retail for 4300,but I never understood why.)) I moved on to the Adept Response and am still happy after 2 years.

I owned the original Hydra and recently tried the PS Audio Power Plant Premier but the SA XE-12 bested them by quite a large margin: more liquidity, more natural tone colors (not as dry as with the PS Power Plant) and I can no longer hear a slight hiss that I had in my system with the Hydra. I'm using it with MAC Wire Delta PC which I like better than the Elrod EPS 3 Sig.

Thanks for all the comments so far. It's interesting that there is no concensus as far as these devices go. It appears to be somewhat system dependent. I put the running springs conditioner on my old front end and at the time it was nothing short of amazing. Probably the single biggest leap in system performance I have had. Now that I have better everything (preamp, amp,cables, dedicated lines) the running springs ruins the soundstaging. There are still some elements of the sound that are better with it in place, but in general, it is better without it now. There are other line conditioner manufacturers out there, but one rarely hears much banter about them with the exception of Shunyata, which I found to not perform as well as the running springs in my system. I have seen a burmeister, nordost, accuphase, etc. Anyone try these? More thoughts on the sound application welcome as I have ordered one to demo. BTW the price has gone up on these things. It better be great!

Essentialaudio, I did own the Sound Application XE-12 and the Reference Line Stage at the same time and A/Bed them. There is no comparison; the Reference Line Stage is far superior to the XE-12. I sold my XE-12. I also own 2 Sound Application RLSs; they are definitely a step up above the Reference Line Stage: lower noise floor, greater apparent resolution, cleaner transients, better dynamics, etc. I understand that SA now has an upgrade to the RLS that lowers the noise floor even more; I hope to try it soon. The only other line conditioner that I'm aware of that may come close to the RLS is the Isoclean at twice the cost of the RLS. Aren't you a dealer for Isoclean?

Also, I have tried different power cords including the Virtual Dynamics' Master series and Night II series, and an earlier version of Purist Audio. However, the best for my primary system (Jadis JA80 mono blocks drive the Watt/Puppies and the Conrad -Johnson Premier 350 drives the Wilson Audio WHOW sub woofer) are the Elrod Statements. There is nothing light weight about these babies. They add a wonderful weight, fullness, coherence, transparency, cleanliness, speed and fluidity. Musical and involving. Now all the power cords in my main system are the Elrod Statements.

Tvad, You had told me that the XE-12, which you got from me, didn't work in your system. According to your post above, you also tried the Reference Line Stage in your system. How did it compare to the XE-12?
