DAC or Upgraded Analogue in SACD units?


I have read that upgrading the analoge section of SACD units delivers the equivalent of using a stand alone DAC wiht the same unit.

What is the truth?

What is the cost?

Which have you done?

Thanks,

I don't view onhwy61's post as contrarian, since the warranty and resale issues need to be considered carefully, and any decision to mod equipment requires a certain comfort level. So you've raised an important point. In my case, the 777 is a long-term purchase that will likely wind up in my secondary system some years hence. Beyond that, the decision to do strictly a parts upgrade rather than a circuit mod simplifies the task of a qualified tech with access to a Sony tech manual in the event that something goes haywire. But you're right: having a unit like this modded in any fashion is _not_ for the faint of heart.
A used or new 777 is way over $2000 now, plus mod is way over 2500 and the lose of warranty! u do the math. Better get a SCD-1, isn't it?

SCD-1 can offer a first class redbook CD sound already but could be "better" in really subtle way, which some people may say "different"

I heard people say SCD-1's Redbook sound can match AR CD2.
Just to throw yet another option at you. Ric Schultz at Electronic Visionary Systems(www.tweakaudio.com) is completing a total overhaul of the Sony DVP9000 DVD/SACD player. You can go to his website for details, but this mod goes far far beyond inserting higher quality parts and reworks the entire output stage and more. What's more, I think this whole thing costs less than $2k, and there's a 30-day money-back guarantee so there's no risk for trying.

As for advantages of doing it this way, obviously you avoid a whole other set of connections and a cable in not having to use an outboard DAC. Best of luck.

Hi Melhsu,

I picked up a Sony SCD-1 yesterday. It's very nice, but, simply doesn't have spaciosness and separation of the Resolution Audio 55 I usually play redbook cds on. I understand that it will improve and frankly, I'm banking on it. But, as of day two, it needs fixing.

I wonder if it's necessary to have the amp and pre-amp running while the SCD-1 is playing in order to get the "full benefits of breakin?"

I'd appreciate feedback.

Thanks all.

Rcprince:

Thank you for your opinion and advice concerning the Sony. I have been burning in the unit 24/7 on the XLO break in track and the changes are astounding. The detail is completely changed by the end of week one. There is actually more detail with more distinguished bass now than with my Resolution Audio 55. There is a more present feeling than with the RA55. I can't tell which I like more now. But, to even be at the point of debate means that the SCD-1 is a winner in redbook mode. One note that no one that I remember has touched upon is that the SACD section also seems to need breaking in. I am not aware of any break in/test disks for SACD. It would be nice to flex the entire range at one time.

Also, thank you to everyone who contributed to my learn curve.

The DAC/upgrade question is still open for me. In spite of the improvement, I am willing to do either, if, by change I will have marked improvement. Either way, it's a cheap shot at the next level. Isn't it?

Best wishes,

Bill E.
