Hi All...

Curiosity got the better of me on these players, so I ran the test that D555 highlighted... below you'll find the results, although the results for the D211 aren't what i'd call conclusive, as its line out 'volume' / power appears to be slightly more than the 111 and 311... regardless... here are the results

Draw from these test results what you will... and at the same time, tell me what you think... because although the units sound good, these facts and figures don't all neccesarily have any relevance to me...

...Amended to now include the headphone out also...

 

[Duncan]

...I should add that these are the line out figures... I see that Eagle_Driver has compared Panasonics through their headphone outs... Would anyone want me to do the same?

I also see that so far D555 has made PCDP and PMDP comparisons through their headphone outs, as well...

Oops

Okay... I'll re-do the tests later on

- but hey, line outs are important too... right?

I will compare the line-outs of all of the PCDPs currently in my possession (except for the Panasonic SL-CT790, which in its North American version has no line out at all

).

 

[Eagle_Driver]

Duncan,

My Panasonic RightMark report has been revised today. The reason for the subpar results was due to the soundcard's input volume was maxed out, and thus the signal was clipping. Today I re-ran the tests, with a lower input volume at the soundcard's software level.

You can see my revised results here.

 

[Duncan]

Hi Eagle...

As you can see... I've now finally updated mine to show both the line, and the headphone outputs

 

[Eagle_Driver]

For comparison purposes, here are the RightMark results for the two most recent top-of-the-line Sony CD Walkman players with G-Protection:


[size=small]D-EJ1000[/size]

Headphone Out
Frequency response (from 40 Hz to 15 kHz), dB: +1.16, -6.49
Noise level, dB (A): -92.0
Dynamic range, dB (A): 91.5
THD, %: 0.088
IMD, %: 0.183
Stereo crosstalk, dB: -65.4

Line Out
Frequency response (from 40 Hz to 15 kHz), dB: +0.02, -0.09
Noise level, dB (A): -92.4
Dynamic range, dB (A): 92.2
THD, %: 0.0044
IMD, %: 0.045
Stereo crosstalk, dB: -86.9



[size=small]D-EJ2000[/size]

Headphone Out
Frequency response (from 40 Hz to 15 kHz), dB: +0.08, -0.55
Noise level, dB (A): -90.8
Dynamic range, dB (A): 90.5
THD, %: 0.174
IMD, %: 0.209
Stereo crosstalk, dB: -66.1

Line Out
Frequency response (from 40 Hz to 15 kHz), dB: +0.02, -0.10
Noise level, dB (A): -92.4
Dynamic range, dB (A): 92.1
THD, %: 0.012
IMD, %: 0.100
Stereo crosstalk, dB: -89.7



Note that the frequency response curve for the D-EJ1000's headphone out has a -3dB roll-off point (from the reference response at 1kHz) at a mere 7kHz! The D-EJ2000's headphone out, on the other hand, can easily reach 20kHz before rolling off by that much (-3dB).


Draw from these test results, then compare them to what you (Duncan) had come up for those vintage Sony PCDPs, what you will... and at the same time, tell me what you think...
(Here's a hint: The USA D-EJ1000's headphone out just plain sucks - in fact, it's even worse than some of Sony's cheaper PCDPs.

The USA D-EJ2000's headphone out sounds much better.)

 

[Duncan]

The (Non European) EJ2000 looks like, if it had a more powerful amp (with more headroom at least) that it will be a pretty kick-ass player... I've only heard a limited European model, and it didn't sound too bad, but was just way too quiet to have a conclusive opinion

...Ignoring the facts and the figures shown here eagle, do you think the EJ2000 sounds good, or does it sound a little too flat... too linear?

 

[D555]

Hello Duncan and all,

Thanks for reporting these measurements. While they certainly don't tell the whole story, it might help supplement the words and help compensate for differences in heaing and headphones. Of course the computers add their own variables.

I would certainly think that based upon theses tests and listening, the D-EJ1000 has a major design problem with the heaphone out and that the D-EJ2000 is demonstrably superior in measured high-freqency extention.

Are some CDR's easier to read than others? I would love to be able to run the D555 through the tests.

Best regards,

Paul

 

[Duncan]

D555...

Its ironic... although this test runs on the x11s D11, D141, D151 and D777... it does NOT run on the D5, D555, D25S - even though standard CDRs work perfectly... I don't know if its because I burnt this using Roxio rather than Nero... or...

Now that has to be more than a coincidence...Doesn't run on my D-5 and D-10 either (the D-250 will take it though). Strange. Could it have to do with the short runtime?

 

[D555]

Hello,

Maybe it can be tricked. Burn some audio tracks first and maybe put the RightMark tracks somewhere near the middle of the CDR.
