yep, ph3 and p5 will reveal a bunch of rega's imperfections but you can keep rega arm if you're patient enough to adjust non-adjustable arms. also these stages "feel" what kind of cleaning did you use on your records before placing them under the needle.
ph3 is a-bit complicated on loading which is also a critical point with mc where you have to solder and un-solder different resistors to experiment. i've arranged for mine an external selector box that can be used outside of the ph3. i was intended to use this box just to measure but than solder directly the neccessary load resistor but now i simply connect this box to the arm cable(directly) and than to the phono with rca interconnects.
