I have just ordered a great system test file from HD Tracks. It's the
Audiophile Hi-Res System Test - Great Sampling Tracks Included
It's normally $24.98, but with the code
AugHD20 you get 20% or $5.00 off. This file has 76 tracks with all kinds of system tests on it including test tones and burn-in track, as well as some audio tracks of different instruments so you can learn to recognize their sound. THey also include 2 DSD options as well as 24/192.
If you have digital playback in your system, this is a great download! HIGHLY RECOMMENDED!!
