<font color='#000000'>I've been attempting to understand what both the real needs for some sort of line conditioning for a good audio system are, and what is available.
I just ran across the Tripplite IS1000 isolation transformer. Parts Express sells them for about $200, which is a small fraction of what the 'audiophile' power conditoning units sell for. This seems to offer many of the advantages of those more expensive units. This particular unit offers 1000 watts output. TL's description:
**********
Tripp Lite Isolator series isolation transformers offer complete line isolation, continuous noise filtering and enhanced common mode surge suppression. Internal low-impedance isolation transformer component with Faraday Shield offers 100% isolation from the input AC line. Secondary neutral to ground bonding eliminates common mode noise, providing an isolated ground reference for sensitive equipment and an inexpensive alternative to the installation of dedicated circuits and site electrical upgrades. Removes EMI/RFI noise, utility switching transients, backround spikes generated by other on-site loads and utility or lightning related surge conditions. Additional surge suppression components placed at both the line input and transformer output combined with full line isolation offers continuous line filtering of a full range of power line noise in all modes. Active transformer filtering with no wearable parts is uniquely able to reduce surges in the worst of power environments to harmless levels. Reduces 6000V IEEE587 Cat A&B ring wave and combination wave test surges to only 0.5V common mode. Model IS1000 offers 1000 watts capacity with 4 widely spaced output receptacles, a 6 ft power cord, circuit breaker overload protection and lighted power switch

Would one of you EE types mind commenting if this might be a worthwhile addition to a decent sound system?
