Here are a few things that I'd do different if doing this comparo again and only had an hour to an hour and a half:
First, I'd avoid Pink Floyd and Radiohead. As much fun as they are to listen to, they're chocked so full of purposely out of phase signals and flying voices and electronic noises that you can't evaluate what's "right". These albums sounded so different on these two players that it was mesmerizing, but not real useful.
Next, or really first, match levels. We didn't do this and it's really critical. The machines clearly had different output levels, yet we simply adjusted by ear, a real no-no.
Next, set up both players with equivalent ICs so that you can move back and forth with ease. Physically switching is a chore and reduced the comparative analysis that we might have otherwise done.
Limit your listening to three or four discs, each with a purpose. On CDs, this needs to include one loaded with glare on lesser machines to see what magic is done, if any. Another disc should focus on midrange accuracy, so a female vocal, either a cappella or with a small group. Next, listen to a BIG orchestral piece that has micro dynamics and blockbuster sound. (I love Mahler for this). Focus on both ends of the dynamic spectrum. Include a really densely scored disc to see how the lines stay separate, or not. (Mahler is good again). Include a solo piano disc with big dynamcis.
When possible, listen in balanced and unbalanced modes. (Both were unbalanced in this case, despite the PD's balanced mode excellence.)
On a hybrid SACD compare the CD layer and SACD layer on both machines.
We could have done that in an hour, IF we'd been focused on getting it done and had all the needed parts. We spent too much time enjoying music and didn't "work" hard enough.
The goal should be to identify performance in both CD and SACD modes, balanced and unbalanced, and comment on balance, musicality, micro and macro dynamics, timbral presentation and, above all, never use the word PRaT. (Just kidding Mike).
Given way more luxurious time, I'd run the transport of one through the DAC of the other and vice versa, if possible (the Emm doesn't allow this). I've found this useful for hearing differences between DACs and transports.
With more time, I'd also pull in the Pink Floyd and Radiohead and do some phrase by phrase comparisons to see what's happen, or at least be able to say, "this one did this and the other one did that."
Finally, with more time I'd just spend...more time, seeing where the investigation leads me and just enjoying the process.
