In the Tripp Lite filter thread in the main forum, Jim recommended I ask you what your thoughts were on using the Tripp Lite Ultra 8 surge suppressor, basically as a glorified power bar. I'm running my Bryston 3B NRB straight to the wall socket on the right hand wall, where it shares the receptacle with a BC68 Noise Hound, and I'll be plugging the Ultra 8 in the left hand wall socket where it will also share that outlet with my other BC68.My main question is, will there be any sonic problems plugging my CDPs, tuner, pre-amp, and EQ into the Ultra 8? Also, where do I plug my powered sub (Paradigm PW2500)? Should it share the power amp socket, and stick the BC68 elsewhere? I doubt it would enjoy sharing the Ultra 8 with the other components.
Thanks.

This unit is only described as designed for computer equipment, and so on, with no stated use for audio.It has been my experience that computer intended units do not sound very good on audio components. The capacitor quality is usually ceramic, the inductors are common mode ferrite (or worse) chokes with high DCR, in short they do more harm than good.
With the 4 isolated outlets, there may be some improvement due to whatever amount of isolation the unit provides form digital components feeding into the rest of the system, bu the 'improvement' is likely to be a mixed bag sonically.
As to a stragey for use, I would try it with just the aforementioned line level and source gear plugged in, with the amp and sub direct into the wall outlet. There will be some 'umbrella' protection from the surge suppressort plugged into the wall outlets nearby, so the amp and sub will not see a full unattenuated surge or spike, but will not get full protection either.
Listen very carefully for a sense of compressed dynamics, a dull or uninvolving sound, vs. a darker background, and a sense of less background hash or noise. These are the two opposing things the unit is likely to do. The first is duemto the computer grade components, the second to whatever actual filterin it performs.

I guess my intention for this device is nothing more than a glorified power bar, and I'll run my system with just the pre amp, power amp and a CD player plugged into the wall, then add the Ultra 8 to the CD player, then swap the pre amp, then try both of them in the Ultra 8. If anyone cares I'll keep you posted! I checked the Tripp Lite website again, and they list A/V after all the computer related applications, so they haven't totally abandonded us Jim." Typical Applications
Personal computers, CAD/CAM/CAE workstations, network nodes, fileservers, point-of-sale terminals, audio/visual devices, to eliminate interference between connected equipment, and more. "

Hi John,I referred B.P. to you because I feel you are most qualified to deal with questions of the nature of which he presents. The fact that Tripp Lite market their PlCs as computer PLCs is for marketing reasons because the computer industry is a much larger market for profits and sales.
The sound quality of their lower end Isobar PLCs is unbelievably good and was sold by all high end dealers back in the mid 80's (not the higher priced "Ultra" series, which I don't think sounds as good). So, it appears that Tripp Lite made a marketing decision and decided to go over completely to the computer marketplace to maximize their revenues, but, as I said, the Isobar line (not the "Ultra") is quite good sonically. When used with a Quantum Symphony, they can really shine sonically (i.e., their Isobar 4).
So, thanks for helping out with your explanation of what to look for in a PLC.
Best wishes,
Jim
