Citizens of Audio Nation : I was reading a thread on the Bryston Circle about system warm-up and one of the posters brought up the topic of de-magnetizing your system periodically. This inspired me to dig out my seldom-seen XLO/Reference Recordings Test/Burn-In CD and run the two de-magnetization tracks ( Demagnetizing Sweep & Demagnetizing Fade ) three times each and Shazam Hot Damn ! It was like I had blankets over my speakers and suddenly pulled them off. The improvement was not subtle...
If you have one of these discs ( or one of the others available ) and haven't done a demag for a while, do yourself a solid and put that baby to work for you. If you don't have a demag disc, it's the cheapest system upgrade you will ever make so get your mitts on one without delay...
I can only speak for the XLO disc but if you spin the black circle, READ THE INSTRUCTIONS BEFORE USING ! Some of these demag sweeps can apparently damage phono cartridges. RFTM, kids!
