John, I have no need to argue with you.
You just made my point for me.
You said "Any differences from the analog stages are SO SMALL that **I** don't hear them and MOST of my friends don't hear them, either. I have only had one audiophile friend over that COULD RELIABLY DETECT the difference and he claimed it was a very SMALL DIFFERENCE."
This reminds me of Julian Hirsch of Stereo Review.
For years he maintained that all amplifiers sounded the same. Then, late in his career he was a guest on Peter Sutheim's radio show "In Fidelity".
When Peter pressed him on the claim Julian said that if one listens carefully there are small differences.
He said it almost as if those differences shouldn't be of any concern to anyone.
But, of course, audiophiles live for those small differences and Julian should have known that all along. And you should know that.
Have a good day.

The Tascam uses 70s vintage NE 5532 op amps in its output stage. Not bad sounding as the Delta sound card in my PC also uses them, but completely transparent?
I too, find it difficult to imagine they have no effect on the audible results. :)
And there has been for many years. A reliable workhorse, sure, but one can do better.
I have an Oppo 103 which also uses the venerable 5532 while the 105 uses the LM4562 for single ended output and LME49724 for balanced.
I'm sure the DA-3000 provides great value, but when you look inside you see other areas that exhibit cost control such as the power supply and coupling caps.
Most notably my now deceased, and sadly missed JVC-XL-Z1050TN CD player. It's been a long time, and I can't recall what op-amps I used in place of the 5532s, but I do remember the improvement.
Just about anything (unless it's already an all-out assault on "The state of the art") can be improved on, sometimes for surprisingly little cost.
Your point regarding the power supply is well taken. Improvements there have always gained me my most significant improvements, most notably, replacing a 7818 regulator inside my Graham Slee Reflex with a Belleson regulator.
I'm unsure if I have the nads to attempt removal of the tiny SOIC op amps in the Tascam. But the unit has a bipolar PS of 7812/7912 three pin regulators. I'll try Belleson regs in those positions.
My opinion is that the ADC in the Tascam unit is special, but that its DAC is just average. You need a better DSD DAC to "hear" these recordings.
The only potentially superior alternatives that I can find for recording to DSD are the Merging Technologies Hapi($5.5K) and the Playback Designs Pinot($10K+). The Tascam is a bargain. Anyone with a DSD DAC who is contemplating recording their vinyl should feel free to mail me an SD card that I will populate with sample tracks and return.
I don't blame you. I wouldn't mess with those either. Even many expert solderers don't like to fool with surface mount devices.
As for the Belleson regulators, I don't think you'll be sorry. As I recently posted on Tweakers, it made a greater improvement than any wire (interconnect, speaker, power cord etc.) change I've ever tried.

Well, I disagree with you 100%. Small differences are of no concern to me. Of course, I don't even hear a small difference between a vinyl record played on my Sota Millennia turntable and a DSD copy of the record. Furthermore, I think that if you bought a TASCAM DA-3000 and made your own DSD recording on your own system, you would understand exactly what I'm talking about.
For me, it's the music that matters -- not small differences -- especially when I don't even hear them.
Good luck,
John Elison

Small audible differences don't matter to me. In fact, I did not audition any component I now have in my audio system before buying it except for my Thiel speakers. It just so happened that the Thiel factor used to be about 10-miles from where I live and my son made friends with Kathy Gornik and her daughter Dawn. As a result, I was invited to a factory tour and I ended up buying a pair of Thiel CS3.7 speakers directly from the factory. All my other components were mail-ordered without ever hearing them first.
Best regards,
John Elison
