How does the Sansa clip+ compare to audiophile sound cards? 2010-12-10 16:09:07 I was considering assembling a quiet pc as my main stereo source for home listening with headphones, but was disheartened because of the very limited selection of silent/quiet pc components available here in Brazil. In this process, however, I was surprised by how close the Sanca Clip+ came to some soundcards like the E-MU 0404 in rmaa tests.I don’t really know how to read rmaa info so it could just be that the comparison is invalid. The tests for clip+ are usually done using 16 ohms headphones while for the sound cards they tend use high end speakers or high impedance headphones. Would the results for the clip+ be significantly altered if a 300 ohms headphone were used?Furthermore, how do these data translate into perceptible differences in sound quality? Would the extra 10db in noise level or the lack of 10db in dynamic range make a real difference? (here's from one test: E-MU 0404 16-bit/44.1kHz/Noise level, dB (A): -96.1 Excellent/Dynamic range,dB (A): 96.3 Excellent /// Sansa Clip+ V-Moda Vibe (Normal Volume) Noise level -89.4/ Dynamic range:89.3 /// The Clip+ drops respectively to -62 and and 62.2 when tested with the UE11(low volume))Another problem is that my headphone amp is showing its age and I fear it may fail in the near future. The data about portable players and full size phones is scarce. Would the clip+ manage to drive something like the HD 650 (300 ohms) without an amp?In more general terms what I’d like to know is whether portable players have a reached a level where they can be used transparently (or close to) for listening with good headphones in silent environments. I’ve been unable to locate abx tests involving portables. How good are they sounding?In yet other terms: Has a U$30 mp3 player replaced U$3000+ cd players (or somewhat cheaper pcs) as a reliable source for headphones? I have no personal experience with portables but this just seems to good to be true.
