using a back-up ups for front end of system

An UPS for the Audio system?

Never heard of anyone doing that. I guess so when your power is out and you get bored you could use it to keep listening to music?

why not get a rack of Gel-Cells and a backup generator too?

I cant imaging an UPS would last for very long. maybe 30 minuits tops?

rremember, your stereo uses alot more power than your PC, it will probably drain the UPS in a very short time

Most UPS type devices are filthy creatures when it comes to generating AC. They are meant as a means to temporarily operate a computer system so that it any data can be properly stored and the system shut down without losing anything. When used for their intended purposes, they work fine. Other than that, they should be nowhere near an audio system. Sean

Sean, I meant using it only to run cd transport, dac, and preamp. I get alot of drop outs and interruptions and with my system playing, the transients created from these irregularities is scary. By the way, I am the one who posted awhile back about the humm emitting behind my rack with everything in the racks disconnected from themselves and the wall socket and all the circuit breakers in the panel off, including the 100 amp main breaker. The only thing I can come up with is that I live by a small municipal airport and maybe it is the transponders? Thanx, Jeff
