While it isn't my goal to review the already well known Etymotic ER-4S, nor really to provide an in-depth look at the Apogee Duet, I thought it worth taking a few moments to post some impressions I've developed after using the Duet as a DAC/headphone amp combination, especially with the ER-4S.
First of all, a quick look at the Apogee Duet in use on my desk:
I have posted some very general impressions in various Duet-related threads concerning this device's performance with my HD580 and DT770/80 Pro, and I will shortly repeat here that I think the Duet does an excellent job as both a source and an amp for these headphones. It didn't take me long, however, to get around to finally listening to the Duet with my ER-4S. Until acquiring the Duet, I had only listened to my ER-4S via my 5G iPod and Hornet. Switching to the Duet in a desktop environment was quite a change for me after getting so used to the sound of my portable setup. To get right to the point, I was somehow bothered by the mind-blowing level of clarity and, especially, detail the Duet brought out of my ER-4S. I have made it a point to take some time to play around with this setup some more and try to figure out what, if anything, I could do to optimize the listening experience with these IEMs.
Today, I have done some simple testing (mostly just having a good time!) listening to Björk's Medúlla and Post albums, playing these albums from start to finish via iTunes with Apple Lossless files. I always enjoy the musical complexity of these albums, and this time around I found myself as involved as ever in the music and sounds (are these different?). Within minutes of starting this listening session, I remarked a stark blackness between notes, and a purity of sound the likes of which I have probably never heard before. The level of detail and sense of space around instruments was lovely, especially considering the fact that I was using IEMs. Still, something didn't quite satisfy me in the same way that my HD580 and DT770/80 Pro have with the Duet. For lack of a better way to explain what I mean, I will say that the music seemed to lack a very slight amount of realism and texture. And I don't mean any sort of veil, but rather something that sounds even better than reality, and therefore a bit on the synthetic side for my tastes.
Then I started considering the configuration of the Duet and of my Mac, and I decided to play with the settings that I'd initially made in Audio MIDI Setup. When I first starting using the Duet, I went right away to Audio MIDI Setup and made sure to set the audio output format to 96000.0 Hz. This setting indeed yields the best results for my other headphones, but after changing the setting to 44100.0 Hz as shown below...
and listening to the same to albums all the way through, I can say with confidence that, at least to my own ears, this brought about exactly the changes I was after. I don't want to say that the results were just like listening to the ER-4S with my Hornet, but the gap was certainly closed a bit. The detail is still there, but I can somehow grasp the edges around various sounds, including Björk's vocals. If I had an appropriate cable, I would love to use the Duet as a source to feed my Hornet for comparison, but that won't be possible unless I decide to invest in a custom cable (1/4" male TS-to-1/8" TRS). The clarity of the Duet's DAC is simply stunning, and with the texture and realism the lower sample rate brings about, there are parts of this music (especially from the Medúlla album) where it actually felt as though someone was physically whispering or blowing down my ears.
That's all I have to say for now, and I hope to hear from anyone else who gives the Duet a try with IEMs. Thanks for reading.
EDIT: Hmm, I really should have put this in the Computer Audio (Computers-as-Source Components) forum. Maybe a nice mod could move it there?
