High end UPS for Expensive audio eequipments

@westom

Like everything else in this discussion, your reading is half-baked. UL 1449 includes testing for effectiveness as a surge protection device in addition to life safety issues like not starting fires after a surge. Do some reading before posting.

Series mode surge protection devices have the best (lowest) UL tested "let through voltage" or VPR for test surges. meaning that during tetsting the equipment being protected would suffer a much lower voltage than with MOV parallel devices.

This is why fairly reliable companies such as Furman, SurgeX, and PS Audio rely on them for their best protection, and have NO MOV’s or joule ratings (for AC protection) and have no sacrificial components (in the AC protection).  Again, if you had bothered going through the design, or reading the spec you wrote so eloquently incorrectly about you'd know this.

Well the absolutely best buy for price, performance, reliability and pure sine wave output is a professional rather than audiophile type UPS with double conversion.

I have one running my entire system for 3 years 24hr/day without interruption.
There is one caveat. The fans run continuously and cannot be placed in the same room as the equipment due to the noise of the fans.

I run a line from the basement closet under the stairs to my basement home theater and also to the main floor 2 channel sound system.

" And finally, UL says nothing about hardware protection.  UL is only and completely about protection of human life.  Who is the UL?  National Fire Protection Association."

Um, not to confuse what you've written with actual facts, but UL (Underwriter's Laboratories) and the NFPA (National Fire Protection Association) are two separate and distinct organizations. 

Further, while UL is obviously concerned with human life, their standards are written to help protect devices and structures as well.  "Only and completely about protection of human life" is an incorrect statement.  Sorry.
