Post Subject: Multiple pp 2000Posted by Bill on: 3/9/2011

Was priveleged to hear Romy's system on Saturday. I must say he's done a superb job both musically and esthetically over the past year, and except for one minor niggle has surpassed what he had in Boston. That was the very low bass, but he has stated that that has also been improved over the past few days by sacrifiving some room for musical esthetics and I look forward to hearing his system again.
On to the PP 2000. As Romy has stated they found a slight defect in the circuitry of some of their newer units and have with Romy's help figured out the problem. I sent my three units back over the past four weeks, and finally received the third unit back yesterday. Before I could listen to them, Romy called to say he was having trouble with some high frequency information when two or more are used together on the same circuit. Last night I listened but could not hear the effect, but my system sounds different from Romy's and is not quite as good at delineating differences. Also, instead of plugging them directly into the wall, I plug them into an Audience AdeptResponse aR2 and an aR1 power conditioners between them and the wall, which may mitigate the problem.
Will experiment further to see if plugging them directly into the wall produces the same effect as Romy hears.
Also would suggest that he try using a cheater plug on two of his units and grounding the chassis to each other might improve the situation by running the noise over the chassis directly to the one ground or possibly running them from three different circuits on the same leg if possible. Any other suggestions on isolating the units from each other?
