Jfacker is right. You could have gotten away with the Pre 5 and saved yourself some $$$ over the Pre 2 if you are using the analog outs from the Pioneer. The Pre 5 is a great ever-so-slightly warmer than neutral pre with no processors and no video switching to get in the way of the audio signal. The Pre 2 will work just fine for what you need though...and with the addition of an optical cable, you will be able to choose between the two processors to see which you prefer (for DVD-V anyway...you will still have to use the Pioneer processor for SACD and DVD-A). Hope that helps.
Pioneer 47Ai / Audio Refinement Pre2 DSP help
I just had Stan Warren modify my Pioneer 47 Ai universal player and I also purchased an Audio Refinement Pre2 DSP preamp processor. As I was reading through the Pioneer manual there is mention of the AV receiver needing to be compatible with high sampling rates (96 kHZ). I checked the manual for the Audio refinement pre and there is no mention either way if it is compatible or not. I am REALLY hoping it is and that I did not make a mistake buying this pre. I bought it specifically because it has the 6 analog inputs for DVD audio and SACDs - I really appreciate any answers you can help me with.
