Thank you all for this excellent thread and especially to Eric for introducing us to great sound!
In speaking with Ian he suggests the UCPurePro (3000F ultracapacitor system) as being better than the LiFePO4+/- UCConditioner. Has anyone compared the Ultracapacitor only approach to the battery if directly wiring to the WR902AC?
Beyond the primary question of “which sounds better?” is also “which sounds better longer?” It seems like probably the battery setup would last longer in Pure mode, but I’m curious how the two compare in sound when they are both in charging mode. Ian seems to think the UCPurePro is still better.
Appreciate your input. Thank you! In the end we might do both and just compare head to head.
