I was most impressed with the micro-resolution, it lays out the sound and reveals the details within. Though very resolving, it also sounds smooth, this is the only sensation of coloration this amp has for me. The amp is also very transparent and revealing of changes in source equipment. Rhythm was very good from this amp, it initially seemed to slow down the music, and everything feels well defined and well spaced over time. It never sounds rushed or hurried, rather, it very easily keeps up with the tempo of the music creating a naturalness that is engaging and realistic.
My only qualm with this amp is the bass. It's not the wow kind of bass I think is a hallmark of most gear these days. It's there and it's tuneful, but it's not the super-punchy rumble many high end systems have.
I would recommend this for discerning listeners who value fineness of presentation over wow factor and in-your-face sound.

Good headphone amp but not great
October 12, 2010
I've owned an SPL Auditor for just about 7 months and have used it with a variety of headphones including the Sennheiser HD800, Beyerdynamic T1, and AKG K701. The specs of this amp indicate possible optimal performance with high-impedance, inefficient headphones and I found this to be true, with the exception of the HD800 (which it didn't sonically gel with, more on that in a bit). It drove the Beyer T1 well enough, as well as the HiFiMan HE-5 (now discontinued). Fast impulse response and strong overall clarity throughout the frequency response are its main pros, and it has a nice treble tilt that can help balance out headphones with a lack of treble. Not ideal with treble-oriented headphones though (like the HD800) for this reason and it has a relatively light mid-range and bass too.
