I'm thinking of getting a moodlabs "Concept" DAC, has anybody tried this
with their SB3?

I had my ecm8000 mic calibrated as well :-)
I made a plot of the calibration values compared to the ones that come
with the drc distribution (ecm8000.txt).
When using this calibration file with drc the sound becomes way too
bright. So I reversed all the values (plus -> minus and vice versa) but
Hi Jaco,
There are FIFO type solutions which don't rely on a master clock type
system, and these were what I was refering to. You're right though,
this is the first I've seen that add's an external clock input to the
SB3, which would allow a much smaller (and cheaper) FIFO buffer.

That wasn't intended as a careful test, but in essence it was an AB/X
or AB/XY test. In other words, we listened to known sources first (A

was A or B. There was no at

I'm of the opinion that it is impossible to make all parties happy when
it comes to blind audio testing. The urge to confirm a predetermined

Hi DC,
I didn't claim that FIFO's and master clocks were something new -
they've been used in the pro audio world for a long time. However, this
is the first solution (at least what I'm aware of) that employ these
techniques for the SB3.

Theoretically it is overkill - since the SB2 has internal regulators,
it will make little or no difference. No-one has reliably measured
better performance with a bet

However it is important to ensure the relevance of the test to the real
life use of the equipment under test. If the test is not relevant, then
the results are worthless.

We've been here a few times, but it is hard to resist! The differences
between speakers are gross - there are huge frequency response
differences. One would expect these would be relatively easy to pick

But digital sources are much more similar is such gross terms. All
