Vinyl Related News and Video’s

Rather than add to existing threads elsewhere, I thought it would be interesting to collate vinyl related news/video’s in one thread for us looking to read/watch/keep up on the latest content.

Here is a long, but very interesting, video of a recent interview of Kevin Gray:

Very interesting video and great thread to give hints on such videos or maybe also new audiophile vinyl release series.

Never heard Kevin to praise tubes so much and mentioning his private all tube recording and cutting setup in planning to do analog tape sources or direct discs.

Also interesting to hear him again on the SFS Mahler Symphony cycle I mentioned so often here. All guys including our host speculating on unavoidable limitations of most dynamic music put on vinyl…listen to Kevin and how the vinyl release wasn’t just preferred by the consumers who compared it with the SACD. Unfortunately the guys stated but didn’t dig deeper into why digitally sourced vinyl can sound so much better than the digital media.

Based on everything I’ve learned, I have a simple theory on this. I’m sure the physics will back up what I’m saying here, but I have to say I don’t have much time to do the thesis. Maybe an aspiring physics doctoral candidate who loves vinyl might opt to do their thesis on this topic.

And so the theory goes…

Recording digital onto vinyl brings the mechanics of motion physics into play. Where DACs work to represent sound as electric signal approximations subject to Electromagnetic physics, the representation of sound conferred by tracing grooves into vinyl are subject to, and limited by, Newtonian physics.

Most DACs try to represent a sound wave by approximating the curve of the line between two sample points. That approximation often extrapolates additional data that do not exist in the original signal. The better ones try to draw a bezier curve. The worst ones draw a straight line.

So what does a cutting lathe draw? With a vinyl cutting lathe, the movement of the cutting stylus is bound by the properties of and limitations of the physics of the stylus against vinyl. Newton’s three laws of motion governs the stylus movement and limits how the groove can be shaped.

As such, vinyl is unable to track wave motions that exceed it’s physical limits and acts like a band pass filter for signals that can only be accomplished via the limits of carving a curve into vinyl… kind of like a car that understeers when taking a sharp corner.

Why does this sound better? My best guess is that vinyl limited motion is physical in nature and our ears are built to understand sounds generated from tangible, physical interactions. Digital waves are unnatural in that they do not originate from physical phenomena, but rather an approximation of a sampling of physical phenomena… at least until they’re cut back into vinyl.

That’s at least an interesting theory! We probably can’t finally tell if this or rather the difference to the studio DAC’s sound enriched by the cutting processes and turntables artifacts and sound generate the vinyl sound.

As also the latter differ from album to album in the case we talk about, my theory is that it’s mainly the (for the vinyl version) missing digital media production step and the somehow different mastering process.

I heard from a friend that MoFi will be announcing shortly three new One-Steps: Eagles, Eagles Desperado, and Cannonball Adderly - Somethin’ Else

For those in the US, you can call Music Direct today and they will take preorders via the phone to ensure you are assigned a copy. My guess is these sell out quickly.
