How many us a Line Conditioner with a Big SS Amp

I had a similar experience with power amps and some of the conditioners mentioned. Two different amps (BAT VK150 tubes and Boulder 2060=qualifies as big (a)SS amp) and 2 different line conditioners (Shunyata hydra 8 and Running Springs Duke). Interestingly during this process I added dedicated lines (20A) for each component. I found that the Shunyata made the BAT amps sound worse. I then added the dedicated lines and the sound was improved. Retried Shunyata and worse again. Now have Boulder, initially without conditioning and now with RSA Duke. I cannot tell the difference with or without the Duke yet. Still sounds great; neutral powerful and articulate. During my frustration with the Hydra, I spoke to the folks at Shunyata several times (very nice and helpful group), they always said (contrary to an earlier post) that the Hydra 8 should perform better than the Hydra 2 on power amps. I got the same response from RSA when deciding whether to put my Jaco on the front end (or on the theater which has more stuff) or to use a Duke because I only need 2 outlets for transport and preamp. They told me that the 2 units were the same, one just had more outlets.

Yes, I use the Mongoose with all of the RSA's. I haven't heard anyone mention a cord that might work better. I used Shunyata Python Helix alpha's with the Hydra. As I mentioned in my previous post, I have a Jaco and 3 Dukes. I asked the folks from RSA which I should put on my 2 channel front end (which is by far the most important to me) and they told me the Duke and Jaco are the same with the exception of the number of outlets. Thus, I use the Duke.
