etc...

If you're happened to be the owner of thos players, would you like to do the RMAA on the players?????

yeah, I know technical specs dont really tell you how devices sound to your ears.

HOW TO DO RMAA:

1. Download & install RMAA & Run RMAA.

2. Set the 'playback/recording devices' according to your system setup.

3. Leave the rest of settings default.

4. Click 'Generate WAV' (diskette icon on the bottom)
& Save wave files to your computer.

5. Load 'Test signal (44 kHz 16-bit).wav' onto the device.
& Make sure you disabled all the EQs and Supreme settings

6. Hook up the output of the source to your soundcard's input.
(in this case, you need to connect your ext DAC's output to your
soundcard's line-in)

7. Click 'Recording Only' button on RMAA. (the big red dot icon)

8. Run 'test signal (44 kHz 16-bit).wav' on the device.

9. Raise the volume until the highest level reaches approx -1 dB.
(make sure the signal doesn't distort due to too much amplication)

10. Click 'Start test' button. & Click OK.

11. Feed the signal. (play the wav file)

12. Save the result.

================================================== ===

To perform the impedance loaded test:
(to see how the device does while driving headphones)

1. Get a headphone splitter: http://www.globalsourcesdirect.com/c...YN-JS5004W.jpg

2. Connect the splitter to your device (or ext DAC output)

3. Hook up any 16(or 32) Ohm earphone/headphone to the splitter.

4. Hook up the cable which connects soundcard to the splitter as well.

5. Do the RMAA.

6. Save the result.

This sounds little tricky, but youll get used to it.

Kenwood players don't have a line-out :/

Well that's the thing, I know how to do those things you posted but I thought there's a way to bypass any processing done by the soundcard. Wouldn't the test results be inaccurate since everybody's using different soundcards?

Well, Line-out doesnt really matter if you dont use amps, right? Im just curious about the headphone-out of KENWOOD devices.

It seems that you use 'M-Audio Audiophile USB' and that oughta do the job pretty well with a good quality interconneting cable

(if there is S/PDIF or COAX output on your ext DAC, you can use it to feed the signal)

Oh I thought you said "external dac," LOL my apologies....

(WHERE DID THAT COME FROM?! LOL)

Well, I think -8dB wouldnt be so bad unless RMAA doesn't recognize the signal. (check the input level if it's set to max)

BTW oh I can't wait to see the result...

I've been looking for the data of KENWOOD devices for a long time- since I want to get one of those for my next DAP.
