If the DAC is the same, how different do CD transports sound?


One interesting topic of discussion here is how audible the differences are between CD players when they are used as transports only — or when they are only transports to begin with.

In other words, in a comparison which keeps the DAC the same, how much difference can be heard between CD transports?

This recent video by Harley Lovegrove of Pearl Acoustics provides one test of this question. It may not be the ultimate test, but he does describe the experimental conditions and informations about the qualifications of the listeners.

He comes to the main conclusion here: https://youtu.be/TAOLGsS27R0?t=1079

The whole video is worth watching, I think.

It’s interesting that the listening panel could detect differences between the players but couldn’t do so when they were connected to the same DAC via SPDIF. Personally, I wouldn’t mind having the same listening panel try to determine if there are differences between transports, but it seems to me that Mr. Lovegrove found it somewhat obvious that there aren’t and I agree with his conclusion.

A firsthand assessment in your system would be much better to draw a conclusion from for yourself then [sic] cherry picking the comments in the thread that allow you to confirm the video narrative that you bought into. 

I didn't "buy into" the video narrative. I presented it as something which seems worth discussing. You've phrased my position here tendentiously. 

And a test in my system with a local CD transport to compare with my CXC would be interesting, but I would need someone to help create blind conditions and make sure the voltage outputs and dB levels were equal to make it more valuable. That's something the "video narrative" did, and described the procedures pretty well.

Your cherry picking comments that simply support the video conclusion did it for you.

@hilde45 not at all what I was trying to convey.
Also, the number of views on the video is not an indication of how accurate the information is. Not sure why you think it’s important.
Looks like you’ve formed your opinion and the conclusion of the experiment described there just feeds into it.
Happy listening!

Sorry to miss your point. OTOH, I thought your point about longer listening as a way of determining differences was valid and something the video did not address. I hope I got that right.

The number of views of the video is relevant because the people cited by name in it have been heard 93k times as holding a certain view about audio. I would not want my name cited 93k times if I didn't believe what the video said I believed. Especially if it was in my professional area of expertise.

@facten Go ahead and believe whatever you want about me, since you've already cherry picked your way toward that conclusion.
