Best CD sound: Marantz SA8001 or Rega Apollo?

And not to beat a dead horse, but the Benchmark people claim to have proved that their DAC can correct for any timing problems coming from the source. In other words, they claim it makes no difference whether you feed it from a CD transport or from a computer. Again, this is something that could easily be verified. If it's true for the Benchmark DAC, there's not reason it couldn't be true for the DAC in a CD player.

I'm responding to 4est.

I think you're being a bit extreme. I used a borrowed Benchmark DAC with my computer audio files and was quite pleased with the sound. But I'm not sure that it bettered the SA 8001, which costs slightly less. (The Benchmark definitely has a better headphone amp, though, than the headphone output of the Marantz.)

This is the sort of thing, by the way, where it would be very easy, and I think helpful, to do some blind testing. Many CD players have a DAC input, so one could compare the sound of a CD in the player with the sound of the same recording playing back from a computer into the DAC. If retrieving data from a CD in real time is really such a problem, it should be audible.

The analogy I've heard is that you need to spend 20k to better them

4est, I'm not sure I'm in as complete agreement with you on this. I have a BOLDER digital modified SB3 that I've been using for over a year with a good linear supply (but not the super-duper BOLDER PS). I also have a Proceed PDT3 transport and heavily modified EAD DSP7000 Mk.III DAC. I've heard newer players and DACs in my system, and feel comfortable in saying that I haven't heard anything yet in the under $4-5K category that makes my transport+DAC sound like crap.

The SB3 as a digital source sounds very, very good, but not as good as my transport feeding the same DAC. In terms of tonality, speed, and dynamics it's all but a toss up. But the SB3 produces a significantly less deep and wide soundstage. Easily heard by most listeners. A friend who had never heard my system before picked it out in less than 15 seconds of playing the same tune on the SB3 after having heard it on disc via the PDT3. I'm not suggesting the SB3 sounds bad, far from it. But the transport does produce a better musical soundscape.

I'm making an extreme sounding point to tell you that (at least in my system) there are differences, even if they are actually smaller in an absolute sense. Would I give up my SB3? Absolutely not. Would I give up my transport? Not just yet.

I have asked if this could be a cable interface problem from the SB3 to the DAC (you know, jitter and whatnot). Some think that may be effecting the soundstaging, so I'm willing to experiment. The transport is connected via AT&T glass.

Gee , not to get back on topic or anything.....I have the precursor to the 8001 (SA8260) and love it. For what I spent I haven't heard anything match it. Also , I've had no reliability problems in almost three years.
Finally , the DAC in the 8260 is superior to that in many amps , to go along with a decent headphone section. The best advice ,though,is audition the equipment. You can read numbers and opinions until your eyes fall out-it's your ears that should make the final choice. Good Luck!!! :)
