Balanced Power BP-3.5 or Hydra 8

Just wondering if anyone has had the opportunity to compare these units?
BP 3.5. I heard the two side by side a couple of weeks ago. They both had good things to offer, but the 3.5 allowed the harmonics to be fleshed out better. That is something I preferred.

Best thing is to compare them for yourself in your own system preferably. Make sure the BP unit is plugged in overnight before making any comparisons.

In the interest of full disclosure, I am a dealer for BPT gear.
