Too bad, I just sold a modded demo unit. Very nice indeed, infact legendary among transports.

I have a stock one that I need to sell if you are interested. Its very good, even stock because it has two lasers, one optimized for DVD and one for CD.

What makes it so special as a transport? Aren't 0s and 1s all the same? I mean, would there be more importance placed on the DAC?

I had the S7000. Coupled with a $$$$ coax cable to a decent DAC, gave me some serious sounding tunes. These things are built like a tank! Even more, mine had DIP switches to disable Macrovision and Regional Coding. The ONLY thing that I did not like about it is that it did not play CD-R or DVD-R's.

No CD-R support? Is this true? Would be a bummer, but 179.00 for a quality transport, I can live with that.. Might have steve mod it when I'm unbroke..

I just told you, it has dedicated lasers. Lower jitter is the result. It's not just ones and zeros. Where have you been? This is talked about all over the forums.

The 7700 plays CD-R's.

Of course not. It has not been in production since 2000. I want $200 plus shipping for it. I will do the auto alignment and clean the heads before it ships.

What are the jitter figures for the unit ?. I looked up the Sony manual but it only lists the usual parameters..

While jitter is talked about vigorously all over the forums not everybody is wholly convinced that it is that important...

The jitter is displayed during the auto-alignment procedure. I cant remember what it was on the last one I aligned....

I've had lots of customers over that past 3-4 years compare this transport to other high-end transports. They all conclude that it is better sounding:

Is this enough anecdotal evidence?

You misunderstand , I am not decrying your mods or the transport itself, I am skeptical about the effect of jitter. Do you keep before and after measurements including jitter and the usual suspects ? i.e are you sure nothing else changes in the process of the changes you make.

In a transport on the S/PDIF output bus, what else can possibly change to affect the audio playback except jitter?

If you say error rate, I don't buy this for the following reasons:

1) playing a track on a CD with no scratches on it sounds identical to the same track on the same CD full of scratches, except for skips of course.

2) when I rip a CD on several different computer CDROM drives, there is no error correction indicated and all of the checksums match, therefore the data is identical and no errors were detected or corrected

3) different S/PDIF cables of the same length (1m or 1.5m) sound different from each other. Dispersion, impedance, losses and B/W limits are the things that can affect the signal through a digital cable. The timing (setup and hold times) on the S/PDIF interface ( a full half-cycle of setup and hold - 177 nsec for 44.1 sample-rate data) is such that errors will not occur until the cable is extremely long (about 80 feet), so errors do not occur due to a cable of this length. Jitter is the only difference.

I'm certain that jitter is the audible effect because when I play the data through my new reclocker (FIFO-based) the sound quality is improved dramatically. All it does is store the data and clock it back out using a low-jitter clock. No data bits are changed, no sample-rate frequency is changed.
