Battery backup

most computer battery backups apparently sound atrocious...putting lots of noise out.

I've used the Red Wine Audio battery supplies (they are not for back up, they replace the AC). My Nagra PLL and VPS (pre and phono) have off board AC supplies and the main units take 12volt dc in..so the Red Wine Black Lightning was fantastic improvement. You have to spend a lot in AC conditioning to maybe equal the red wine battery's...

Does your DAC have a DC input? If so, I bet this route makes it sound better...

PurePower units are your answer.

I have read 'computer battery backups' are not ideal for audio although I have never tried it. BUT take into consideration that for computers there are 2 types of battery backups. First is just that - a backup meaning you run off of wall power until power fails and then it switches to battery. The other is an on-line UPS meaning you always run off of the battery.

That being said there are 're-generators' made just for audio. 2 that come to mind are PS Audio and PurePower. I just got a PurePower 1050 and run my source - integrated and sub off of it. It lowered the noise floor for me and does not restrict dynamics or power. At a fairly loud level of listening I tripped the circuit breaker and listened for 25 min and the battery level dropped to 50%. I do not know at what point the PurePower shuts down (depleting the batteries to 0V will be the end of the batteries) so there should be a point where the unit shuts itself off to protect the batteries from totally discharging.

Thank you

Currently using a Liebert UP tation regenerator on my complete A/V system except for amps and subs. Puts out a pure unwavering 120 vac and I must say, I'm VERY impressed with its abilities. Plus it also provides for battery backup by the nature of how it works. AC-Filtering-DC-battery-DC-AC
