Still-One, have you ever A/B'd your Olive and 500 in a transport face off?

I did a lot of comparing of the DAC's in the MCD-500 vs the Olive 4HD and found they were very similar with the 500's just a bit better. If you go to this thread you can read some of my thoughts as time passed.

Currently I have the digital outputs of my MS-300 and Olive 4HD running thru the Esoteric D-07 DAC but as you can guess that is primarily for listening to music off the units hard drives which what I use for 90% of my listening. The MCD-500 is connected via analog outputs direct to the C-1000 for listening to SACD's or the occasional CD. There is definitely a difference in the sound from the digital outputs of the MS-300 and the 4HD going thru D-07. I was doing some comparisons over the weekend trying to identify the pluses and minuses of each. I am using two different digital cables, one Analysis Plus and one Acoustic Zen and I will probably have to swap those around at some point to see what impact that has.

I am guessing that some of the difference is the MS-300 is saved in FLAC and the Olive 4HD music is bit for bit.

I made that point...but for error on a ps or ns scale, will it be audible?
who knows, 4 options
yes (agreed by all)
no (agreed by all)
yes (percieved by few)
no (perceived by few)

so jitter between word bits, no impact
jitter between words, possibly

my opinion, ps or ns shifts won't be audibly detected...
not after all the smearing and smoothing by cables, filters, speakers, etc.

so if we have a pulse every 1/44100 ~ 0.0000227 sec (22675 ns) that is shifted/distored by a max 1000 ns (the worst in the test) most were 1/10th that much...
that is ~4.4% temporal 'error', since speakers routinely produce that much, can it be 'heard'?
and if it shifts everything equally (or close) all bets are off, because then it only a delay

Transports can make an audible difference, but not always. And it's not always the most expensive one that sounds best either, like anything else, it comes down to synergy.
