Well, this is the first I have heard of the RFI problem! I don't have a cell-phone, but I do work around a lot of (possible) RF interference. I work at Cornell university's particle accelerator, and the control room is almost certainly loaded with various EM frequencies. I know that people who own cell phones simply can't get any reception in the control room, and have to go at least 20 feet away to get reception. The problem is probably the pulse forming network in the linear accelerator section, which is only 10 or 15 feet away from the control room: big high voltage power supplies, rapid switching, thyrotrons, etc.
I have a MacBook Pro, and find that the headphone out jack is just simply not good enough for me, even driving something as cooperative as the Sennheiser PX100's. So I want a DAC/AMP combo, with a line-out as well as head-phone out. I have narrowed it down to the Apogee Duet and the iBasso D3, and was just about to pull the trigger on a D3, as I couldn't justify the extra $250+ for the Duet given that I don't plan on doing much (if any) recording.
Then I read this . . .
I don't suppose if anyone knows if the Duet is prone to RFI? And I'd appreciate any thoughts, comments, or suggestions anyone has. I have Grado SR225's that I want to drive with the Amp. From what I have read, the Duet should handle those phones just fine, if maybe not as well as the iBasso D3.
Thanks in advance!
You could always incase it in mu metal. :^)
Great solid little amp. I am still impressed with the rock solid fee and fine sound.
Good to know, jamato8! I've read a lot of your posts over the past couple months, and very much appreciate them. Thanks!
I don't suppose you've had any experience with the Apogee Duet? Specifically with the headphone amp section?
