sony scd-777 dac vs PS Audio DLIII DAC


I have the sony scd-777es (without mods) which i want to improve... I am getting a great price on a new PS Audio Digital Link III. Does it make any sense to use the sony as a transport connected to the PS Audio DLIII? In other words, is the DAC in the 777es better than the PS Audio DAC?

If the sony's inbuilt dac is not better, then would level 2 mods on the sony be a better use for the money than the PS Audio? The sony's slowness doesnt bother me, I am only interested in improving the sound. thanks

Don't know any more about these two pieces other than what I've read but, if I were a CD and not SACD listener, I'd most likely purchase the PS Audio DAC directly from Cullen Circuits. I would choose their Level III or level IV mods that include a brand new unit that Cullen supplies ($1390 and $1490, respectively). I own three Cullen digital amps and the build is superb, with flawless function. As great as the SCD777 likely is, it's not new and all things pass. When that day comes I'd look at the best maintained/lightly used Esoteric transport I could find. In the past year I bought a P-03 that embarrasses the Sony-mechanism dCS Verdi it replaced.

Of course, any outboard DAC takes you out of the "one box" paradigm and requires addition of a digital cable. I've found that digital cables have substantially audible differences, unlike my experience with analog ICs and PCs.
Thanks Jb0194, this will be very useful when i have a bit more cash to afford the Cullen mods -- hopefully soon! :-)

for the moment i can only afford the $650 bargain i am getting on a nearly mint PSADLIII.

Wondering if any one knows if this will be an improvement on my sony 777es (to be used as a transport and for occasional SACD) or if there is somewhere else I can spend the money to improve the front end?

Thanks
the 777 is a good-sounding player (I used to have one) - you probably would need to buy a kilobuck DAC (plus a good interconect...) to hear a significant difference. if you can't audition first, I'd say don't do it.

as far as spending $650 to improve your front end, you might want to spend it on good interconnects for your 777 if you don't already have nice ones, or a power conditioner - I think that power conditioning has the most effect on digital.
I've owned a Levinson 39, 390s, 360s/37, Wadia 861SE, BAT VK D5 23bit, MF A5, Krell SACD standard, Sony SCD-1 and XA9000ES plus a brief stiny with an XA777ES. Oh, I had an ARC CD 3 as well. Hardly a Sony fanatic. It amazes me how many people hook up bargain outboard DAC's which require more cables and power cords for their mediocre performance to be realized or even better, they spend good money on modifications to outdated gear. I mentioned the Sony because it is world class performance for a bargain basement price...no mods or outboard nonsense needed.
Dave sure does seem to like that Sony, and based on everything he has owned, I won't argue with him ! I agree on all the mods and DACS, and have never went there myself either. I am currently happy with my NAD M5 Master Series SACD/CD, seems to work well for the level of performance I need. If I was going to look at anything more expensive then the NAD M5, I would certainly think about the new Sony, which is quite a bit cheaper then the NAD new.
