High end UPS for Expensive audio eequipments

I have the same setup as milpai, so whole house surge protector, dedicated lines, and Brick Wall on sensitive (digital) gear. The power lines here are underground, I have stable power, but I still pull the plugs when I hear that thunder getting close.

akg_ca is unfortunately incorrect when it comes to surge protection. A lightning bolt, or induced voltage from an EMF will happily go through most modern equipment's power supplies.

HOWEVER, some is going to be more sensitive than others. Tube amps and pre-s for instance are more tolerant due to naturally high working voltages to begin with. Tubes are easy to replace too. :)  Devices with CPU's to control displays, remotes and EQ however are most at risk.

It is however up to a great deal of debate as to whether or not improving the AC signal will have any subjective effect, and many power supply designers feel that so long as the voltages are within spec (110V-130VAC) the user will not be able to perceive any difference.

Personally I find the addition of Furman's LiFT to really open up the treble.  Maybe I'm high. :)  I'm no power conditioner cognoscenti though,

APC S-10 or S-15. Proven, dead quiet, reliable, and not a rip-off like so many power conditioners are. Get one and don't look back.

@bojack -
I had terrible experience with an APC UPS. Not for audio, but for my desktop PC.. It worked well for about a year, and slowly I started having issues with my PC crashing or hanging for no apparent reason.
I pulled out my (non existent) hair trying to figure out the problem. Replaced memory cards, reinstalled the OS, replaced the power supply... So much frustration. So many hours wasted. Even took it to the shop which gave it clean bill of health and charged me $60..
It ended up being the UPS polluting the line with so much noise that caused the PC to crash. I hooked it up to an oscilloscope, was shocked at what I saw.
UPS removed, problem solved.
I will NEVER buy another APC product again.
