Power conditioner plugged into computer battery

Well, thank you for the comments, but the answer to APC S15 is a no. So far, it does not seem as if anybody had serious comparison between APC and the heavy weight audiophile conditioners such as PS Audio, Audio Power, Shunyata, etc. The existing reviews on the internet tend toward peace of mind and security, as opposed to music quality. Even Stereophile didn't focus on sound performance. Incidentally, security and integrity is what the computer industry expects from surge protector/UPS equipment. So something does not add up. The best I heard was about video quality improvement, and that is not enough a basis to judge music performance, especially when we are talking about upper division stereo separates. APC is well recognized in the computer world. Yet with severely limited review on the audio side, I am not about to spend that kind of money on a rather unknown piece of equipment.

You know - think this through - nobody makes what you are looking for...

I just wing it, and got a used Power Wedge 112. Very interesting result! My computer battery is fully charged, or supposedly fully charged. It's definitely better not to plug the Power Wedge into the APC UPS. No I didn't experience any loss of slam in the bass like what others commented. Pluging the 112 directly to a wall outlet just gives more "natural" sound. I don't want to use words like "vividness" or "crisp". There are plenty of CDPs that give you the razor sharp crystal clear sound which can almost kill your ears within 30 minutes. Skipping the UPS gives me a deeper soundstage and more transparent sound. The fog is lifted.

Audio Power did say that the 3 options for the isolated outlets should be experimented. With my equipment, the balanced AC is actually least desirable. The floating output gives the best result.

Thought I'd breath life into this old thread I came across running a search. I'm researching UPS' as well -- I'm buying a BPT-style balanced power device for my source components and display (the amps and sub will just go into the wall's dedicated lines). I'm also installing a whole-house surge protector. In any case, the outfit building my balanced power device suggested a UPS with voltage regulation and pure sine wave output to go between the wall and the balanced power unit.

It hasn't taken long to figure out that the vast majority of UPS, even the APC Smart UPS unit, don't really have a pure sine wave. Instead, their's is a line-interactive, stepped process, essentially boiling down to it being merely a standy emergency power unit.

My question on UPS' is this. Where do the DUAL-CONVERSION ONLINE ups' fall into the equation? As I understand it, these regenerate power full-time, same concept as the APC S10 or the PS Audio PPP. If I'm not connecting amps and subs to it, should I have any fears of limited current (1000va/700w)?

Thanks!
