This was a wildly popular AC conditioner that had the MultiWave II+ upgrade ($250 value). The P600 is not exactly a power conditioner but rather an AC regenerator. What this means is that it takes incoming AC current and converts it internally to DC voltage and then back to AC current out through its eight outlets. This may sound like a “big” task and indeed it is which is why the P600 has a huge and hefty transformer inside. The benefit of this AC regeneration is that it cleans up the electrical current as it undergoes the process of AC-DC-AC. Sensitive components like turntables, CD players, DACs and preamps benefited with varying degrees when they were plugged into it. Even some power amps sounded a lot cleaner when it was plugged in (200-250W amps should be okay). Peak cumulative current is 720W but can stretch to 1,000 with short bursts. With the MultiWave II+ upgrade done you could try out varying oscillations in Sin mode to see if that changes the sound in your component or make incremental changes to the voltage and hear the results.
Cosmetically, the unit looks good. Minor scuff marks here and there but nothing major. The P600 is a big and hefty unit so shipping will not be cheap. We will however, securely pack it for safe shipping.
