Jbatlanta, Sdcampbell offered some great reference recordings. Especially "Ocean Grove". Also, Sean makes some valid comments regarding "slow, bloated bass". I also like his terminology regarding "instantaneous thrust". That's a good one Sean.
Of course, if you want to go to extremes and you enjoy classical:
Tchaikovsky "1812 Overture". Erich Kunzel conducting the Cincinnati Pops Orchestra. Telarc #CD-80541.
Many an amplifier have been put into the "protect mode" due to this recording.
The WARNING LABEL on the cover reads as follows:
"WARNING! The cannons of the Telarc digital "1812" are recorded at a very high level. Lower levels are recommended for initial playback until a safe level can be determined for your equipment."
I think that says it all.
