Guys,
I also try a new PPP unit at home with my system. I found that it improves soundstage, wider and deeper. It increases micro details which normally I could not hear when i use direct cabling thru wall socket. It definitely improves bass details, It creates a very dark background so that the resolution, listening fatigue all improves. But one issue makes me nervous during the test week is upper mids and highs. I found that there is a lack of high frequency energy. The high frequency objects and instruments are more laid back and thinner, contrary to wider and stronger mids and lows (First I thought the sound without PPP had too much noise at the upper frequencies which make a brighter presentation so that PPP corrected the problem, however after hours of listening i concluded that this is a problem). When these two come together, it makes a darker and less exciting presentation with a tricky tonal balance. Has anyone detected that kind of similar problems? Is the unit sensitive to break-in period and/or placement?
Any feedback welcome.
