What the fuck are you lot talking about?
1, UPS usually serve one function: Allow a battery backup should the power drop below a certain threshold. Some, like the one that is 2 foot from me now, also have rudimentary surge protection and act as a various amp multiplug outlet, but other than that that's all the do.
So I don't know why you think that there's any "power conditioning" as such.
Want proof? The top of the line UPS unit from APC (biggest company) only specs out at 5% THD. That's the same threshold for a normal household socket. The threshold for "distortion" in audio is 3% THD and every power conditioner out there aims to be far lower than that.
Also, the voltage steps on most UPS are +/-10v, Cheap Power conditioners =/-5v and expensive ones or regenerators are +/-1v.
2, In line capacitance is not power conditioning. It just stops unwanted oscillation of voltage. Nothing more.
3, Products like powerplant do not make audio dull (unless all this time you've been perceiving the noise and coloration caused by dirty power, emi, rfi, etc as pleasing to your ears). The studio I work for just invested $40,000 in a massive industrial version of that to power the whole building. It's not smoke and mirrors - it completely decouples you from all the dirty power and equipment feedback from other other users. They basically take a massive 400v feed, change it to DC then generate a pure and pristine AC feed again.
4, Cheap power conditioners are not worth the $30 of components in the $200 box. They are nothing more than glorified multiplugs with the convenience of rack mounting.
5, Balanced power regulators, Hz rectifiers, Isolation transformers and Voltage regulators are worth every penny - and by this I mean the expensive ones.
The PS audio unit that Raphie had, does <0.8% THD, and it one of the best units out there for clean power and isolation.
however the ideal setup would be
PS Audio generator ---> Power Balancer. That way, you get the lowest possible THD, no EMI, RFI, No DC, and then have fully balanced power so no noise and a much higher noise floor.
