Laserdisc-The godfather of ALL consumer optical disc media

Way back in 1999 I used to work at an audio salon and we used to do Dolby versus DTS comparos.Hence both copies of Goldeneye.

I had the AC-3 version of GoldenEye (until I bought the DVD). I used to watch the first 10 minutes daily: still my favorite Brosnan movie.

@StantonZ
To this day whenever I do a Dolby VS DTS Lasedisc demo (*obviously a LOT less than in years past*) 100% of the time even non audiophiles/videophiles hear the difference!
The last one was a few years ago at two different times with two different coworkers who came over to listen to my system. I played the exact same demo for each of them.First we started off by playing a 320 kbps MP3 rip of a CD streamed to the Oppo and then playing the CD it was ripped from.
They heard the difference.
Then I played Jurassic park 2 in Dolby AC-3 and then DTS. Both heard the difference and said the exact same thing that people used to say back in 1999.That being the fact that the DTS version sounded louder.

EVERY SINGLE DTS LASERDISC THAT I ALSO HAVE THE DOLBY DIGITAL VERSION OF HAS GOTTEN THAT EXACT SAME COMMENT!!

I always address the issue by saying there is a lot more information on the DTS disc,so it is going to be percieved as being louder.
The interesting thing was with the second coworker who came over.He asked me to play the same scene again in both versions and commented that he heard some stuff on the DTS version that he could not hear on the Dolby version. I agreed with him.

DTS uses a LOT LESS lossy compression than Dolby does. The Dolby AC-3 bistream coming off of the disc is 384kbps (*and the Dolby AC-2 sountrack that they used to use in movie theaters was 320kbps-Kilobits per second*)The DTS bitstream is the same as with a two channel Compact Disc at 1.5mbps (*megabits per second*)Which is why it replaced the 16 bit redbook bitstream on a Laserdisc.

I cannot believe I remember all of this shiggity!

Can you say geek-a-ramaaaaaa???

(*btw at the time I had an Oppo BDP-83 Blu-ray and a Pioneer DVL-919 Laser. As well as an Onkyo PR-SC5508 pre/pro*)

@xjghost
If memory serves the DVL series of Laserdisc/DVD combi players consisted of the following in order of appearence on the market:
(*and I have had most of them*)
Pioneer lineup
DVL-700
DVL-909
DVL-919
Elite lineup
DVL-90 (*based on the DVL-700*)
DVL-91 (*based on either the DVL-909 or the later 919. They looked essentially identical*)
The only one that I haven't had was the DVL-909

HOLY S@#÷!!
Now it is clearer than ever to me the benefits of having low Jitter!
Backstory-For some reason that I have never been able to explain other than some cnanges in design,the DVL-700/DVL-90 had no issues with passing the bitstreams of DVD'S and DTS CD's through the Meridian RF demodulator. However the DVL-919/DVL-91 will not. In order for me to be able to get sound I have to run a second digital cable straight to the preamo,bypassing the Meridian. So I just did that today in order to play the DAD and a DTS CD.
Anyway I popped in a couple of redbook Cd's and wondered after playing if I could hear a difference between the signal going straight to the preamp versus passing through the Meridian and it's reclocking circuitry.
OH YEAH!!!
I played one track and heard it immediately. The track was one that I used to use as demo material even though it isn't audiophile fare. Michael Jackson's Stranger in Moscow. At the beginning the raindrops were more distinct and I could better hear each one. When the bass line comes in it is deeper and much more well defined passing through the Meridian.

WOW Jitter SUCKS!!

Just heard something else on amother CD that while I HAVE heard it before. It was not clear or defined,so I could not make it out like I just did. I also noticed I am not experiencing listener fatigue after a few minutes of cranking the tunes with redbook CD's like I do when I stream them to the Oppo.
