I'm assuming that $180 pays for a lot of engineering time and expensive equipment used to optimize the signal.(?) I've used Stereophile's Burn-In Noise (track 20) on Test CD 3, the System Burn-In (track 9) on the XLO Test/Burn-In CD, and the Equipment and Cable Burn-In Signal (track 38) on the Chesky Audiophile Test Disc Vol 3. I can't imagine anything working much better than the Chesky or the XLO (I prefer the Chesky).
