Keep in mind that even where you position a cone under the equipment could influence the music coming out of your speakers. Seems that you need to play around with your setup and cabling to (possibly) get back to something closer to your previous "sound". Have you made the changes recently?
Why does it sound less dynamic?
It has been a great puzzle to me. I have upgraded my whole chain from a SFL-2 with a PA-7 STASIS amp from Nakamichi connected to some PBJs, three Racing cones connected to a pair of Gershman X-1s, and SW-1 companion woofers and some old japanese digital front end (CHEAP*) and switched the power cord to Synergistic Master Couplers and the set up sounded explosively dynamic etc . . . .and since then, I switched to Sonic Frontiers Power 2, and added the BEL CANTO DAC-1, to my Panasonic DVD player, which was wired with Synergistic Research Alpha Sterlings and the whole set up sounds worser than before. The soundstage is less dynamic, the inmediacy is gone and overall, I feel a lot less excited by the results. I would say that somehow the digital sound sounds a little more artificial and annoying than before. What is wrong? Is the amp slow sounding? Is the digital front end bad? What caused this problems? I need help with this connondrum
