Does Digital Try Too Hard?

Digital glare. A plague of digital sound playback systems. It seems the best comment a CD player or digital source can get is to sound “analog-like.” I’ve gone to great lengths to battle this in my CD-based 2-channel system but it’s never ending. My father, upon hearing my system for the first time (and at loud volumes), said this: “The treble isn’t offensive to my ears.” What a great compliment.

So what does digital do wrong? The tech specs tell us it’s far superior to vinyl or reel to reel. Does it try too hard? Where digital is trying to capture the micro details of complex passages, analog just “rounds it off” and says “good enough,” and it sounds good enough. Or does digital have some other issue in the chain - noise in the DAC chip, high frequency harmonics, or issues with the anti-aliasing filter? Does it have to do with the power supply?

There are studies that show people prefer the sound of vinyl, even if only by a small margin. That doesn’t quite add up when we consider digital’s dominant technical specifications. On paper, digital should win.

So what’s really going on here? Why doesn’t digital knock the socks off vinyl and why does there appear to be some issue with “digital glare” in digital systems.

A quick update based on some learning lessons from last night’s listening session:

1) CD demagnetization is essential

I’m going to go out on a limb here and make the claim that whatever a demagnetizer does to a CD is fixing a fundamental problem of the CD medium. Every time I demag, I am happily surprised and think to myself, “this is what CDs are supposed to sound like.” I’ve made demagging part of my pre-listening ritual. It drastically knocks down digital glare.

2) Schumann resonator placement matters

I had one of my Schumann resonators on top of my speaker. I moved it directly on top of my CD player. Some frequencies were much improved. Others weren’t. The best location was closer to my CD player but not too close. It actually increased digital glare by behind too close. 

3) Battery powering the front end is a great idea

I have finally got my entire front end on battery power and the digital glare is virtually non-existent! Most analog sound that’s ever come out of my system. Dynamics don’t collapse like many people say. Of course I’m using large batteries which appears to be essential when using battery power supplies. I’ve got each component on its own battery and power supply. The takeaway here is that one should provide the cleanest power possible to their front end gear and when they think it’s as clean as it gets, make it cleaner. Moving my front end gear to dedicated battery power supplies has been the most impressive upgrade and now I’m wondering why it wasn’t the first audio project I did. Clean power is that essential.

Cleaning the electrical embeddings is like upgrading from a 200 dollars amplifier to a 2000 one... 

Put a tourmaline on your Schumann Generator....

I will try that. I’ve got a spare piece of tourmaline that needs a home. What should I expect?

what kind of S.G. have you?

If the sound of your audio system lack some clarity that will gives to you some more...

If you need more clarity use a little Herkimer diamond with it ...

if your system lack body and flesh, use my golden plate ( thin phone shungite plate +copper tape on one side) put the shungite face on the S.G.

For an optimal result use them all, the stones will balance the shungite effects, and the copper will polarize his effects... These golden plate are my own creation and low cost and very powerful... Nobody gives a dam because it is low cost … I dont sell my idea...  :)

My best...
