tiny bit of the signal from the other audio
channel. With Crossfeed turned off,
the m900 operates with strict channel
separation (like any other headphone amp).
Finally, there's the most esoteric feature
of all: a choice of four response modes
for the filter on the D/A converter. The
manual explains which of these might be
best for what kind of material; you can
experiment to find the one that suits you
best. I never developed a strong preference for any particular mode, but your
ears may say otherwise.
In use
This is the easy part of the review. I
plugged in the m900, my Mac recognized it instantly, I set the volume to 70
dB, fired up my reference music playlist...
and left this bad old world behind for a
few hours. Wow, does this box sound
good-and accurate, too. When I can
tell the difference between two different
MP3 bit rate versions of the same track,
that's a good sign.
The clarity, detail, imaging, and frequency response were absolutely
exquisite, whether I was listening with
relatively cheap old earbuds, my Alclair
and Ultimate Ears custom in-ears, older
high impedance cans, or my higher-end
phones. The quality was most obvious
on the fancier phones, but the cheaper
cans and earbuds never sounded so
good (ever).
The only time I felt I really needed
High Power Mode was when I plugged
in my AKG K240 Monitor headphones,
venerable 600Ω beasts that like a lot of
oomph. Low Power Mode was perfectly
fine for my lower-impedance phones.
Crossfeed is a lot of fun if you've never
used it before, but I personally would restrict it to checking finished mixes and/or

listening for pleasure. It does add a tiny
but noticeable sense of "reality" to music,
but if you're listening for a tiny digital edit
or artifact, you need to know for certain
which channel it's in.
Speaking of listening for pleasure,
here's another big thumbs up for listening
to DSD files on my computer with the magnificent quality they can deliver. Wow!
Conclusion
That big thumbs up is a good place to
end this review. The m900 is an amazing listening experience that brings the
best possible quality to your headphone
monitoring, and it makes a dandy D/A
and interface for powered monitors,
too. Grace Design sound in your pocket
for a price that doesn't break the bank?
I'm sold.
