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.

For most of the history of CD players there have been only a few transport manufacturers… but CD players and transports sounded quit different with the same transports. Companies that wanted to get the most out of sound would go through extraordinary feats to mechanically and electrically isolate the drives to perform their best. And it works.

 

This is why, although CDs are waning in popularity there are still a number of high quality transports out there. 

If a DAC is good enough, it buffers by storing bits and releases them in a precise enough clock, the bits just before conversion should correct inaccuracies in most transports. It becomes hard to hear the difference between the transport and a file in a storage device. 

I tried over a dozen, from highly rated DVD players, inexpensive audio transports to the latest PS Audio expensive transport.  I chose a fully upgraded/moded Arcam Delta with a new transport mechanism.  I had to upgrade the resistor fuse twice and double it's rating as two different boards blew and had to rebuild.  Otherwise, I would choose a Jay's Audio CDT3/M3 for $5,000.  The digital cable also makes a difference although I only tried 5, I'm keeping the Synergistic Research Atmosphere Euphoria X, best bang for the buck and only SR cable I own. 

Gentlemen - I usually refrain from contributing to such post but I'm compelled to do so this time.

First - a system has to be of high fidelity to be able to distinguish the differences of anything. The system includes equipment, it's set up and the room acoustics.

Second - EVERYTHING matters. Everything!

I switched transports, from a Meridian 800 transport to a Oppo 205 used as a transport. In both cases, a $4,500 (retail price) MIT coaxial digital cable was used. The Meridian sounded natural and dimensional with a wide, deep soundstage.

The Oppo sounded thin, artificial and lacked any dimensionality. Also, the bass was significantly compromised.

I usually state anyone is welcome to come listen for yourselves but my system is not operating because my wife issued me a divorce, which we're in the process of completing.

Jasonbourne71 - when I get my system operational, I'll offer to pay for your transportation and lodging to come and listen to my system if you agree to post your experience. Friends told me not to do it because you would be biased. I enjoy sharing good music and would enjoy experiencing your reaction - no matter what that reaction may be - because I'll gain insight to individuals. You'll either clearly hear a dramatic difference or your won't.

To be completely honest - I'll also have others present during the demonstration who will select their favorite and describe and write down what they hear for each session, so it will be a collaborative effort. And, of course - it will be a blind listening test with a variety of things switched in random but documented order.
