How does Yamaha CD S2000 reproduce super audio?

Interesting Bill. I have compared the Yamaha with a few other non-SACD players (Krell cad 300cd, Rotel rdv 1060, Arcam cd74), Yamaha sounds decent, but exaggerating, its sound is a bit more like coming from a bullhorn compared to Krell or a more moderate Rotel; perhaps, Yamaha sounds a bit more cleaner than Arcam but Arcam has a deeper base. The SACD-s that I have tried, Krell and Rotel (in the normal mode)
have more depth and soundstage than Yamaha (in the super audio mode).

Taking into account that  Yamaha is the biggest and heaviest player I have seen (almost the doble in size and weight than an average), the outcome is not perhaps what one would expect. Though of course I think, in general terms, its not a bad player. 

Niodari,
I haven't heard the cd-s2000, but having recently taken possession of the newer cd-s2100. My understanding is that the 2100 is closer in relation to the top of the line cd-s3000 than the earlier 2000. 

I can tell you that I can hear a distinct difference between sacd and cd layers in some (not all) of the discs I own. More air and spacious sounding. Some discs (like Roxy Music Avalon) the difference is subtle and I believe a testament to how well this player handles redbook playback. By "bull horn", I'm assuming you mean a more forward presenation? 

From the reviews I've read the cd-s2000 appears to be well liked, but it didn't garner "must buy" status. I wonder if the luke warm response sent Yamaha back to the drawing board to build the cd-s2100 more in the vein of the cd-s3000? Have you given the cd-s2100 a listen?

Yakbob, I have never compared s2100 or s3000 with s2000, and never auditioned them. They have essentially different DACs, s21000 and s2300 have built in ESS Sabre 8 channel DAC, where s2000 likely uses PCM (I guess 2-channel) DAC. This may give some difference in super audio performance, though I am curious whether this also extends on ordinary CDs.  An inexpensive OPPO BDP 105 has a similar ESS DAC, as well as more expensive (almost 4k more) McIntosh MCD550. I am also also curious on their sound  performance, compared to the above ones, and even more expensive super audio players (like Krell Cipher or Audio Research cd9, for instance). 

So far, I am not convinced with SACD players, in general. I have noticed much more sound improvement using Reimyo DACs (I use DAP 777 and there is a newer model DAP 999). In general, JVC 20bit K2 signal processing is perhaps a quite efficient converting technology, at least based on my experience so far the most efficient one. Another advantage is that K2 CDs need no special CD players and can be directly copied.  

With Yamaha s2000 having a bullhorn (megaphone) sound I meant an "echo-like" (indirect) reflective sound. Although, there is really a lightly notable such effect.  On the positive side, Yamaha s2000 reads almost all cd-s easily, ones that other players cannot read, and is faster in reading and moving in between the tracks. 

Willand I too have the S1000 Yamaha out of the box it sounds good.
