I don't think it's quite fair to say "dumb enough" here... there are lots of reasons one might prefer one portable dac/amp to another. In this case, the DACport is rated at 1.5 watts, whereas the smaller and cheaper DACport slim is rated at 450 mw (the DACport HD that you referenced is not cheaper; it sells for $199). Also, it appears that these units will be shipped right away, so if one needs it now, it could make a difference. Finally, the DACport has been thoroughly reviewed by Stereophile, where experienced writers hailed its "tube-like midrange," which is important to me as I use a tube preamp and like that type of sound. CEntrance described the DACport slim as "better" recently, but it's not clear to me which sonic parameters are included in the "better" description, so for me it's a question of getting a proven item vs. a new one that may be better. If you prefer the sound of the slim, that's totally fine with me, but I'd urge all of us in the audiophile community to try to avoid referring to the audio choices of others as "dumb." You might not like the sound of my Magneplanars, but I might not like the sound of your preamp.... doesn't mean either of us are dumb. Thanks!
