none so far

The P-Series must have a good reputation for reliability. A local music store that I visited recently had several of them that they rent out every week as PA amps for weekend warrior musicians. They were 5-6 yrs old and they hadn't had any problems with them getting abused by amateur musicians every week. Hmm..... interesting. inflatable houses rental

Good bass drive, quiet fans, solid construction, Good smooth midrange, not harsh like some other pro power amps.

At 35 lbs. it's a bit heavier than some of the newer power amps with the lightweight switching power supplies, but so what! Stick it in your rack and fuggetaboutit.

The channel attenuators do not appear to be balanced with each other. In order to balance the channels by ear, one attenuator needs to be set one click higher than the other. No problem.

Solid if not exciting performance. Good power for pro audio applications which is the original design intent of this model. I use it as a PA mains amp for 5 pc. jazz group. The first time I used it (one channel mono mains and the other for foldback monitors) our pianist/vocalist remarked how she could really hear herself for the first time and that it helped her performance.

I A/B'd the P4500 in my home stereo system (Arcam FMJ CD36 / VTL TL w.5 tube preamp and Linn Keilidh 2-way floorstanders) vs. my Bryston 3BSST. No, it wasn't as detailed as the Bryston. There was just a bit of haze compared to the open and transparent sound of the Bryston BUT it was clean, unfatiguing, and had very good drive in the bottom end.

For what I paid, absolutely no complaints whatsoever. I'm looking for another now. A solid, excellent choice for PA or for hometheater.

It smokes the Behringer power amp we use at church.

POWER. the thing is capable of driving any speaker to it's maximun thermal, and more importantly audio fidelity. when you have an extra 12db of headroom at your ususl maximum listening levels, a speaker can perform !!

It makes you sick to your stomach when used as a sub amp. Do not stand too close to a cabinet tuned to 24 hz!!

This is Yamaha's top model of the p series power amps. Let me stress the word power! 460wpc @ 8ohms. 1440watts bridged into 8! I'd used this amplifier both as stereo 8 and for a 4 ohm sub. It had no problems driving a 4 ohm cab bridged. The stereo mode ran my 2 W-horn PA cabinets, each with a 15" and Horn tweeter, the sound power delivered from these 2 spakers is incrediable. The power that this amp puts out is evident in the air around the speakers, you can feel not only bass, but higher frewuencies as well. I've never been in a room where with a sigher spl than this!! good job yamaha!
