None,it sounds very powerfull despite beeing used in a 8 ohm configuration rather than 2 or 4 like most run their amps.It is a quality amplifier period.

None,i wish i had more ,well i do but it's the smaller ones pa502 series,two of those for my 5.25 and 4 mids by Mb Quart.

A high end amp from a company known for it's high end home HIFI,i can't believe how clean sounding this amps are.They also look really classy with solid aluminum casing for cooling purposes,the back plate is enamel plated,how many amps can claim that ?,i love my amp and together with my a/d/s/ rs.2 12" subwoofer it boogies.My signal comes from a Nakamichi cd 40z Head unit,then thru a PPI eq i can't ask for more.

I am surprised there isn't more mention of Nakamichi amps. I have been using two of the PA-1002s for the past year in my car. One running a 2ohm paralel load for the highs, and the other for the subs. They have played rock solid ever since they were installed. They provide the kind of clean, high end sound you would expect from a Nakamichi car audio product.
