Bifwynne.
Your output impedance of your AR P8 being 200ohm is fine to use 20ft of interconnect with, as even if the interconnect was 100pf per foot (=2000pf for 20ft) that equates to a -3db of 400khz which is bat hearing teritory.
Paraneer.
For me to calculate yours with your 5mt of interconnect, I need to know the output impedance of the Pro-ject Phono Box S pre-amp, not the load impedance you've posted. Saying that, I've done a google on this Pro-ject and being solid state, I would guess it similar to Bifwynne above.
Tube output phono stages or preamps and passives would have the big ? on them, with these long interconnect runs.
Audiobrian the OP, needs to post what his phono stage output impedance is to see if he will get 100% sound quality transfer. But it looks like he's missing in action, even though he's the one who started this thread.
Cheers George
