Power conditioner help

From my experience I’d say you are both correct in your comments. I was in the shop one day and saw a couple of Tripp Lite isolation transformers laying around. One was an IS1000 (8.3 Amp rating) and the other was an IS500 (4.2 Amp rating). I figured I’d see what they’d do since the current readout on my Panamax 5500 usually read 3.4 Amps when playing both components in my system. I put the amp through the IS1000 and the media player through the IS500. The noise floor of the system dropped significantly but it was also obvious the system was being choked. The PRAT suffered terribly, as did the sound stage, dynamics, etc. But hearing what it did with the noise floor was certainly enough to make me want to investigate a unit appropriate for my system. In conversations with Bryston I learned that as a result of their testing in order to avoid the detrimental results I had experienced with the undersized isolation transformers they actually use a 30 Amp transformer in the 15-series units and a 40 Amp in the 20-series units. So, from my experience, I can attest to the ill effects from an undersized power conditioning piece, but likewise, when the unit was right-sized for my system (actually a bit of overkill I’d say) the results have only been very positive.

Cheers,
