Substitute "jump" with "pressing skip keys" and "sequence" with "selecting tracks with numerical keys".
Here's the previous post:
Play a CD, any CD, but preferrably any of these CD titles listed here for the test:
Jennifer Warnes - Famous Blue Raincoat, track 3 and 7
CCR - Cosmo Factory, track 5,6,7,9
Dire Straits - Brothers in Arms, track 4
Dire Straits - On Every Street, track 9
Eagles - Hell Freezes Over, track 10
Start by playing the selected CD. Use a preceeding track first, and not the ones listed here.
After about 30 seconds, use the skip forward key to advanced to the track listed here. You may then play this track to its entirety or just for 2 minutes. Take note of the sound. Stop play. Press Stop key once only.
At this point, if you have a mute button on your pre-amp, use it to mute the output.
Now select the test track using the numerical key. If it is the track 4 of Dire Straits Brothers in Arms, press number 4 on your remote control. Do not use any of the skip keys.
Watch the counter on your CD player tick. At the 12th seconds point, hit the skip back key to repeat the track. Do not use the numerical keys.
Unmute the pre-amp. Compare the sound you hear against the sound you heard before.

Does the 15-sec "track selection" method work for Transport + DAC combo?? (nt) - Kenji 07:24:24 06/13/03 ( 3)

- That mode of play is known as 'redmond access'. nt - Methos 14:21:30 06/10/03 ( 5)
  - And you deduced that by using the scientific methos. -t - The Killer Piglet 14:34:46 06/10/03 ( 4)
    - Exactly! I also had to killer few lab piglets to test my hypothesis, however. nt - Methos 14:51:51 06/10/03 ( 3)
      - But your hippo thesis is surely flawed if piglets were used? Hippos are much harder to kill.[nt] - chris.redmond2@bushinternet.com 15:43:38 06/10/03 ( 2)
        
        Well, I did break a few hypodermic needles on the skin of the hippos, won't that do? nt - Methos 15:48:20 06/10/03 ( 1)
