Got the Duet yesterday and really have not stopped listening to it since.

During the first 3 hours, heard numerous "pops" at irregular times, so i connected the breakout cables to the Headroom Max as well as the X-Can V3, but still the pops persists.

Called the tech folks at Apogee and Jay told me to disconnect the firewire 800 laCie external drive, as the timing of the 800 speed 1394 drives is interferring with the 400 speed operation of the Duet. Well, this fixed the noise but brings up another issue of not having the use of the faster 800 speed connection.

any experience here is greatly appreciated.

aside from this minor detail, beethoven's 9th, the butterfly lover and also sprach zarathustra all opened up enormously, as if the Denon AH-D7000 was seeing the outside world without windows or shades.
the soundstage just went out! stretching across the top of my head, i can literally hear the winds, the percussions, and the bass, in front and in the back of my head.

toccata and fugue shock my upper body with enough force that i felt my aeron chair vibrating.

i am very happy!

now, do i still need a better amp? (the Grace m902 is on sale, i hear)

I have an OWC Mercury connected to the FW800 port of my iMac and a Duet running off the FW400 port with no pops or other interference of any kind. In fact I'm playing music off the external drive right now. What sample rate do you have selected in Audio Midi Setup?

anytime!

i am expecting my Grace M902B anyday now, direct from Grace.

i also ordered the Denon RCD-CX1 mini component with SACD player so to listen to my SACD collection while at the office with the Denon AH-D7000.

as for our Shure se530, i overlooked that it was named Product of the Year for accessories by Stereophile magazine. interestingly, this is like after 2 years the cans were introduced.
