All of the above are fine and should do the job-- I use the Delos 'The Music/ The Tests' Delos CD DE 3179.
I use the XLO produced CD for "burn in", magnetic sweeps, and some set-up info., but for deciding on up-grading components, speakers, ICs, PCs, and spkr. cables, I use "real" music that I'm intimately familiar with. I've just never been able to get comfortable with "audiophile approved" music. IMO, you should use the music you really know and like to make up-grade decisions-- use good recordings though. Cheers.

Since there is no single disc that does everything, I was thinking about burning a disc composed of the specific songs that i like to judge the sonic attributes of components or systems by. By having several different types of music with very special attributes all on one disc, you can pretty much put a component or system through ALL of its' paces VERY quickly without any mucking about. Simply drop the disc in and sit back. This way you can find a comfortable position, get situated and retain that point of view for the whole presentation. Having some type of remote volume adjustment would pretty much seal the deal. Sound like a plan ??? Sean
