Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?

uberw, et al,

I remember way back in 2004ish at the Chicago Shw seeing the Disc Cutter. My biz partner at the time bought 2 identical discs, one was edge cut.He brought a cheapo portable radio/ cd player. seem impossible tht we would hear anything. And yet,: the improvement wasn't night and day, but it was obvious, pointing out the limitations of the equipment used for evaluation

Had I heard the NDMs in my system prior to making ONE cable change (from a quality toslink to a prototype coax) I probably wouldn't be as over-the-top as I am for the HUGE improvements I am hearing with NDM

YMMV

+ 1 elizabeths...well thought out reply

I took the plunge and purchased the Machina Dynamica ndm tweak last week..I figured, why not..it won't bust the bank..and if it does..I am in the wrong hobby for sure 8). Truthfully,I wasn't expecting to much from it and made the decision to go ahead and give it a whirl anyway. For whats its worth..I do like tweaking my system if the money involved is not to cost prohibitive. After following Geoff's installation instructions,I sat down and hit play on my PS Audio DMP transport. 

Well..I must say.. I did hear an immediate sound change.Whether or not you do is dependent on your system I would guess. What struck me straight up was a more cohesiveness to the musical fabric across the frequency range,maybe a bit less low level distortion coming through? The whole of the presentation seemed a little darker in character overall [like swapping driver tubes in my preamp]..not a bad thing,but of course, it will be a system dependent and personal like or dislike condition I would think. Is it a cd media digital playback game changer? No,not for me at least.. But I decided to leave ndm in for the time being as to get a better handle on it with some more listening time down the road.. but.. I can recommend trying it if the tweaker in you needs to know if it would,or could, make an improvement in your system.  

For those who have tried the NDM thingies, are you using a front-loader or top-loader? Any above-disc clapping being used? 

No clamping in a Discman ... Lol.

As basic a top loader as it gets.
