That is so true, the fun, frustration, and yet ultimately rewarding experience. The parasound 5125 is 185w at 4ohm, 125w at 8ohm per channel (used for the 880 which is 8ohm and all surround speakers also 8ohm), all 5 channel active. The sae a501 is 375w at 4ohm, 250w at 8ohm and has 2 channels. I checked out the Ricky Lee Jones on youtube, that is indeed a nice testing track, pure vocals and classic guitar. Makes a lot of sense, why you choose this track. The one I usually test is Boston their first album - More than a feelling, peace of mind, etc, just because I've known it my entire life. I'll get it right eventually.
