Indispensable Tool!

@stuartk Peanut Gallery...the original trolls...I like that. For $20 it's worth it to hear for yourself. I was skeptical of it all those years ago until I tried it and now try to use it at least twice a year. Like rodman9999 said, it's great for breaking in components.

All the best,

Naysayers are so predictable.

Naysayers said the Wright Brothers were nuts.

Igor Sikorsky was out of his mind.

Sir Frank Whittles engine will never work.

I am willing to give the Ayre disc a try.  I'll look into buying one.

Been using the Densen Demagic, it’s been around for a long time. Sometimes it affects the highs a bit, sometimes not.

@czarivey Yes, you could burn the files to a CD. Or just copy them to your music library and then play them through whatever software you favor — Roon, Audirvana, etc.

On the recommendation of a friend, I bought and downloaded the Tellurium files in late 2022...because for $25, why not. With new speakers and new audio components, I tend to play track two on repeat for a few days / nights, just to limber ’em up, as it were. Seems efficacious but perhaps I’d hear the same difference if I played white or pink noise for the same amount of time — or if I played the Bunker Analog Stereo Test tracks.

Honestly, I’d completely forgotten about Tellurium’s file #3, the system revitalization track. Thanks to OP for the reminder.

For the last two days my system sounded a little closed-in, less lively than I remembered. I just played track 3 twice, at moderate volume. Now, with favorite recordings, there’s more sparkle, spaciousness, and aliveness.

Am I kidding myself? I concede I might be. But even if what I’m hearing is some kind of placebo effect, I am happier with the performance of my stereo system right now than I was yesterday or two days ago. I’ll take it. At $25, this is a cheap tonic for the ears/brain.
