I have a PPX3 that I got about a month ago, and I really like the sound of this amp, but, I'm currently in the process of having some of my concerns about this amp addressed by Mikhail (The person who owns singlepower) because I'm really concerned about the workmanship that went into creating my amp. I'm not trying to start anything, so people please don't jump on me, I'm just making sure this guy has ALL the facts before making up his mind. I'm a little upset that I didn't know anything about the issues around this amps build quality, and had I known all of the facts at the time I might not have purchased this amp. Yes, this amp sounds GREAT, but build quality is also something i'm interestead in too. Just my opinions on what might help you make up your mind. My goal is for you to have an amp your happy with when it's all said and done.
