Is there an SACD that can play cds well?

do we need a DAC with SCD-1? and does sony has its own DAC or we need to add external DAC?

Dynamics, to answer your question in short - No. However, both Sony's SCD-1 (or Marantz's SA-1) has two digital outputs in RCA and TOSLINK. However, these outputs are for PCM only which means that you can only play redbook CDs with them. Accuphase uses a proprietary standard to connect their own SACD drive and DAC and I doubt if anyone else would support it. My conclusion is, if you buy the SCD-1 or SA-1, you don't really want to use a DAC since the built-in DAC are quite good. But then, no one would stop you if you insist on buying a dCS Purcell/Elgar combo.

I find it funny that no one has mentioned the relatively dismal quality of the Sony SCD-1's analogue output stage. Compared with the rest of the player, the components used for this stage are surprisingly pedestrian. I have the Marantz SA-1, because I felt it had slightly more transparency and tonal accuracy compared to the SCD-1, but a friend had his SCD-1's analogue output stage replaced with high grade components and I don't think I've ever heard anything sound so real.

Globalquest...

For the good of the order, could you mention who did the upgrade of your friends SCD-1? I have heard from other sources that such an upgrade does, indeed, improve CD playback.

Now both of you have me interested, I just hope you are not going to tell me that the upgrade cost more than the original price of the player.
