I have the 640p with an upgraded power supply (something you can do over time) and it competes with units many times its price.
Even with the standard power supply it is a very good performer.
The 651p should be a better choice since the components used are superior.
I use mine with a Denon dl103 MC cartridge, into a naim 5i mk2 amp and the results are very dynamic, spacious and musical.
Hope this helps
