A good system will, of course, reveal the strengths of the source, but also the weaknesses. It will also reveal how much better a better table/arm is. The P5 is a great value, no question. That doesn't make it a giant killer, just a good choice at its price, with it's own set of characteristics. One thing I would pay special attention to in pairing a P5 with a system out of its league is cartridge matching and set up. You want to make sure that there are no nasties in the upper frequencies to be revealed. I would error, if necessary, in the direction of smooth on top.
