I agree with you John, system synergy is key but I do find personal listening preference plays just as big a role ... needless to say that it varies tremendously in the audio world.
As regards the symposiums I use throughout the entire system with consistent results everywhere. Double stacked configuration under my AA player (w/ gr.3 balls) and under my YBA passion amp (w/ gr.10 balls)... in single stacked configuration under the whest audio dap.10 with similar results as described above by you .... they are simply the best isolation device I've come across. I do however find that an islation base underneath the rollerblocks further improves their overall performance ... especially in the bottom end.
What powercables did you use in your system prior to the elrod statements? The only obstacle in my system would be their unidirectional flexibility, which is a real problem in a narrow space between cabinet and wall, especially when you need to further bend them at the ends to reach the YBA and Hydra plugs. I use the Hydra 4 powerconditioner in my system (with additional isolation here too) with shunyata anaconda vx, a taipan alpha and a precept (from revelation audio labs). I'm looking at upgrading from the taipan as we speak but don't have any elrod dealers nearby and fear that the statement may not be able to fit in my system due to its limited flexibility ... and am tempted to go for another anaconda on the amp due to the synergy you mention above with conditioners. What I like most about the anaconda's is their transparency ... it gives me an opportunity to use interconnects and speaker cables to fine tune the overall sound of the system. The anacondas offer refinement in the highs without constriction or roll-off, have a nice organic character, are not bass shy in my system, offer wide soundstage, are very quiet and clean as well, with speed (but not quite as fast as the electraglides) ... similar to most cables in this price range ... but the elrod statement has been highly recommended to me, especially for the amp and I would love to hear one but at the moment it's not a possibility. From what I'm told, the elrod adds more weight/body to the overall presentation compared to the anaconda alpha. Any thoughts/suggestions on this topic? By comparison, the Precept is also very good. It offers excellent speed and dynamics with truly visceral bass (but that's not what I like) and is very open in the highs ... overall an excellent contender who ended up on the DAP.
Sound Applications is not new to me, and I think along with Shunyata and Transparent Audio, they are probably among the top 10 best conditioners around for sound and I think each one offers its own synergy with a particular set of powercables. For video I hear the Gray's are the best.
Thanks for your thoughts, will defintely try to audittion an elrod if I can find a dealer.
