SACD recommendation
My Sony SCD-C2000ES SACD changer has decided to read only SACDs, and balks
on CDs (skips, stops dead, or won't read at all). It looks like I can ship it off to Sony for repair for a minimum fee of $119 (goes up if there is abuse or moisture damage), or I can start looking for a replacement. The Oppo BDP-95 seems like a well-built option-it's gotten good reviews. Does anyone have experience using the BDP-95 as a CD/SACD player in a standard stereo system? Is the user-interface clumsy without a video screen? Are there more attractive options? I'd appreciate your comments and advice. Ed Presson |

Ed Presson I don't know if this is important to you or not, Ed, but for what it's worth, the ESS "SabreDAC" (the best sounding IC-based DAC on the market, BTW) used in the BDP-95 doesn't actually "decode" SACD. What it does is take SACD data in from the disc transport and CONVERT it to Linear Pulse Code Modulation (PCM). I do not know what the bit rate of the converted PCM is but if it's 16-bit, 44.1 KHz as some writers have suggested, then there's no sense in playing the SACD layer at all, you might as well just listen to the CD layer on all of your SACDs and by extension, there's no reason to buy new SACDs since the player converts the SACD data into regular CD data anyway. Your Sony has a real single-bit DSD (SACD) processor in it and it actually processes the SACD data directly and correctly, rather than down-converting it the way some players do. In fact, Sony players actually convert regular CDs to DSD (SACD) data before converting them to audio - probably a better solution. Now, I don't know if all non-Sony SACD players such as those from Marantz do what the OPPO/SabreDAC combo do, but if real SACD playback is your goal, then be careful what you buy. |

What it does is take SACD data in from the disc transport and CONVERT it to Linear Pulse Code Modulation (PCM). Looking at http://www.esstech.com/PDF/sabrewp.pdf, they feed the DSD stream into their digital filter, which operates at a very high frequency. I doubt that there is any better way to do it: you have to get rid of the very high HF noise levels present in DSD somehow. I do not know what the bit rate of the converted PCM is but if it's 16-bit, 44.1 KHz as some writers have suggested, Any why would they do that? It'd easily be detectable in measurements, if not by ear. then there's no sense in playing the SACD layer at all, you might as well just listen to the CD layer on all of your SACDs and by extension, there's no reason to buy new SACDs since the player converts the SACD data into regular CD data anyway. But the real advantage of SACD is multi-channel recordings, not just stereo. The difference is readily audible, even in blind tests. Your Sony has a real single-bit DSD (SACD) processor in it and it actually processes the SACD data directly and correctly, rather than down-converting it the way some players do. In fact, Sony players actually convert regular CDs to DSD (SACD) data before converting them to audio - probably a better solution. That's what every single-bit sigma-delta converter does. Including the $1.50 ones in MP3 players. Andrew. |

That is Phony all right, I not even buy a battery if I see a Phony logo on it, I advise everybody to do the same and never ever buy anything from these crooks again. The Oppo BDP-95 seems like a well-built option-it's gotten good reviews. Does anyone have experience using the BDP-95 as a CD/SACD player in a standard stereo system? Yes, sounds great and decent file support for dvd-A, flac and I asked Oppo for new firmware for SACD file support from Hard Drive. If only more people where asking for that I am sure they will implement that. Is the user-interface clumsy without a video screen? Yes. :-) Are there more attractive options? Hardly I'd appreciate your comments and advice. Ed Presson Edmund |

What advantage might the DSD-to-PCM conversion provide this listener? Not much I can think of. But I have to admit I did not ( Yet! ) looked into detail about that strange noise shaping stuff in SACD, which I not fully understand. As far as my info goes, it is the impulse that is better with SACD vs PCM but unfortunately, there are not many recordings available that are truly HD and even less HD recordings that are DSD recorded. Of course it is of no value to convert a PCM recording to SACD format, I don't expect anything better than the original recording. :-) In a few months my new speakers arrive and I will do a lot of listening and comparing. What I like to see is a "simple" test SACD with complex wave forms, I don't know how one can accurately measure such signals but I am very interested in the analog output of SACD players using such signals. I am sure it will help a lot in the discussion which IS actually better rather then one like the sound of a certain brand/model. Since there is some progress in Ripping and burning SACD's I guess it wont take that long before someone makes an SACD with such signals. To come back to your question, I don't know any good reason why one would prefer an additional conversion to PCM unless the DSD too analog filter is very bad. I have not yet done any A/B comparisons. I doubt that I'd hear the differences, frankly, with my aging ears. I would be curious about the possible differences between the two conversion approaches, if anyone could provide an explanation. IMHO there is no way an additional conversion can make a recording sound better. With better I mean realistic. BTW If you do own an Oppo, please ask Oppo for DSDIFF support so that we can play DSD formats from Hard Drive. Edmund |

You could probably measure the top-end roughness as increased distortion - assuming that you had a distortion analyzer with sufficient resolution. Dunno about the bass. Like you said, that's pretty subjective. |

Thanks for your comments and explanations.
I've been listening to the Oppo BDP-95 quite a bit since I have a seven-day full return policy from the dealer-I want to explore all the aspects of the unit. I hooked to an old TV to double check all the audio settings. Most of the defaults were already set to my preferences, only the HDCD converter was set to "off." I cannot tell much difference between the Oppo and the Sony player (which now only plays SACDs), except for the fundamentals of the deepest bass which are firmer and more "located in the soundstage" than with the Sony. The dealer suggested that I not make any final audiophile judgments until the unit is "broken in." I'm a bit dubious about the need to "break in" a player, but It is getting a lot of use since I'm home this week and my stereo is set up in my work space where I spend most of my time. Thanks again, Ed Presson |

Thanks again, Ed Presson The idea of "breaking-in" electronic components such as CD players, amplifiers, preamps, etc. is pure nonsense. Even more nonsensical is the notion of breaking-in cables. These are audiophile mythology of the highest order. Now it is possible that some components might actually require break-in: SOME speakers, and SOME phonograph cartridges MIGHT benefit from being run-in to make suspensions around speakers and attached to cantilevers of cartridges attain their required amount of suppleness, but even that is necessary only on a model by model basis. IOW, not all cartridges need to be "broken-in" nor all speakers. |
