No, its just pathetic...
Its vibration control, again like static plenty of info out there, ever thought how they make communications in a tank understandable?
Of course moving the CD player away from the cause of the vibration may be a better solution, but as pointed out this is vibration that cant be measured only heard...

Eh how, this is audio myth...
160kg again we are getting into myth area, again.
I suspect there are no measurements for this, just anecdotal information...
Are you sure of that, me tinks you need to do the comparision again. 2 yrs ago i would have agreed with you , but this has not held up with back to back comparisions when it comes to CD's. Pc base music only moves ahead when listening to very hi-res playback not direct comparision with CD's. We have done the comparisons at least 20 times over the last 2 yrs and i still stand by this until i hear better ...

PS: The pc guys got new stuff again , we will see next weekend ...

Why are CD players better than hard drive (or SSD) based media, cant wait to hear the explanation and the data...
Wot no data just anecdotal listening stories...
Yes anecdotal like yours .....

You do know that even with PC's they sound different, yep you should check that out with your anecdotal filter on/off .....

It data, you either read it from a hard disc and buffer it into memory, or you try and read it of a moving compact disc almost in real time...then you transport the data to a DAC...
I presume these listening tests were done sighted...And the same DAC was used for both sources...
Of course as long as the data gets to the DAC intact (ie bit perfect) there will be no difference is the resultant sound...FACT (let us presume that noise issues!!!! have been catered for.)
I presume there is a price break for these superior CDs or are we referring to any CD player...

The trouble is that there are so many variables in play - I tend to favour the music server approach, purely on the grounds that it should be easier to better isolate interference. I noted in the recent hifi show that one room that delivered clean sound did so when sourced from PC, but degraded very significantly when the Oppo unit was used as CD transport - same DAC used in both cases.

Mace,

Expensive everything, CD, dac, even the damn PC AS quite as a cd player when on ...


We are not like the great one, we actually do the comparisons and not in a vacuum. PC's sound different , there is good , better, best . Software used is important too, DAC, cabling , powercord, etc.

We are not getting together to fool ourselves, sighted or not , when you spend thousands on a piece and admit it's bettered , its because it was. A few years ago i got out of expensive digital CD PLAYERS because i was heading the PC way . I can tell you it has not been proven to better CD player playing CD's as of today, at least not in our circle, not in the listening sessions i have been privy to.

Alas their is new stuff on the horizon, upgraded everything with new software and big talk , we will see this weekend ..

24 bits from PC? SW resampling? Both may produce (produces) better sound than a CD player.

marce, don't try parsing logic, this is performance art, not technology.

I know I just find it crazy the lengths some will go to, to solve a perceived problem, and adding 160kg I would suspect you could withstand a seismic event.
How susceptible are record decks affected by airborne vibration as I would have thought these were probably the most sensitive components used.
I was hoping that some sensible information regarding how bad vibration in domestic listening environments was, as my only real experience with audio and vibration is vehicle communication systems, where vibration levels are high, and where SMD components are preferred because they tend to stay on the board, have low mass and tend not to be affected by vibration that much, even MLCC X7Rs (decoupling obviously).
At the moment I am not using my record deck due to an unfortunate attack on my tone arm by one of my lovely cats!!! Now 160kg weight may have helped in this instance...

Seems that 160kg may just get to the load limits of the metal enclosure, it would be one of those U-tube videos with a squashed CD player after adding the last brick. Now if you are really that crazy why not just build a vacuum chamber and mount your cd player inside suspended on wire, vibrate that. Now finding a vacuum pump that didn't make noise may be a problem, I've yet to hear one that wouldn't be worse than just playing the damned cd player by itself. Just put your electronics in a separate room if the in-room vibration is that big a problem.

And yes I have gotten a TT to do some nasty things with low bass, but that was at stupid sound levels anyway, the neighbors were on the phone complaining about the bass bleed into their house!
