Thanks for the topic, misc-audio
I've been using an early ripped version of this for over 25 years, a gift from a friend. Every so often when the thought strikes me, I give it a tumble.
Would I now spend this amount of money for the difference heard? No. And, an added caveat. Watch volume levels. Early on, I damaged a Z-Man Tube buffer. The Purist disc mellows a perceived edge to a digital source...some might say a tad more analog...more for the perfectionist. I don't claim to understand the science, just the calming perception in my system. Without the Purist disc, sure, I would experiment with the Tellurium Q System Disc.
Here's where I could be cutesy and quote some subjectivist vs objectivist to fuel the fire. "If you haven't tried..."If it doesn't measure." But, why? It's a really fun hobby if we just allow it to be. I am over the top serious about chasing realistic sound in my laboratory. However, with friends and audio buds, I elect to play, banter and include silliness. Life is brief and valuable. As Mom once said in her 80's..."It doesn't take long to smile."
