Prp Amps are designed for a different purpose and I would stick to Home Audio designs.
As far as the ZR amps I know people that rate them over the Panaxonic Digi Amps which I have and they have both. I happily use the Panny and if the ZR is better I would consider it.
Other amps to consider used are Plinius and Sim Moon which are great pieces. Sim Mooon if you can afford them and a Plinus 2nd. I was talking to a dealer yesterday and he convinced me of the great value of the sonic attributes which the Sim W-3 has. I want one bad!
