Stagger, you need to come back here & I will sit you down, when you leave you will have either drank the Kool Aid or not. Trust me, we are all hearing something even when dithered down to 24 bit. Between Nick, John & I we have some pretty decent systems for playback & we all notice it. I have no plans on selling my MR-1000 even though my FR-2 is fixed now, it sounds better & it is more than just a pre amp.
Listen to my RCMH & compare it to last year or the year before, besides the brightness (thanks to the Mix Pre) listen to the mids/bass & tell me there isn't more presence or dynamics, whatever you want to call it but don't tell me it isn't closer to the real thing. I was in similar spots for all three years, running Blumlein. I am not saying that they are not tonally different but what I am hearing is more of a lifelike presence on the DSD recordings. I made some damn fine 24 bit recordings IMO but DSD makes me feel like if I close my eyes I am there again better than any other medium I have recorded with does. Who knows maybe it's the AD stage but it does sound better & it doesn't matter whether you are listening to the MR-1 or 1000.
I agree with you though you would think 24 bit is 24 bit but something is up, I can't explain it but there is something different, it is more real. I would hope in the last 10 years of doing this if I have learned anything it is to trust my ears. I am not so blind as to be seduced by a new box & loving it just b/c I own it. Regardless of whether we want to call it noise shaping or DSD it is only available with one of these Korg recorders at the moment, when other manuf's come out with DSD we shall get the true answer then but in the meantime I will call it a DSD trait. Regardless it isn't an argument of what is better but just a fact of what I hear in my recordings.
