I'm a few hours in and what a sound!...I bough the 846s this morning, finally had some time to listen (very briefly) to them powered via my nuforce udac5. I think my jaw dropped. It is audio bliss...all frequencies well balanced (using blue filters so far) everything clear, staging unbelievable and that BASS what a F#$@ing kick!...I have a high end audio system at home but this is my first high end IEM as I seem to be spending more and more time near my laptop. I am in awe on the sound these beauties are pumping...I also have the 215s for everyday that I can knock around and even tough I love them there is a muddle in the sound signature and its very difficult to isolate the frequencies and thus the staging is not as precise - you can sense the high end signature of the 846. I also felt that the 846 are much more comfortable in my ears. The 215s being a tad lighter get more easily overpowered by the memory part of the cable making the cable exert its own demands....the 846s are perfect. They are of course soooo expensive and it all depends on one's budget of course but if you really appreciate music, crave it and live for it - don't hesitate - buy them!
In any case I love my combo so far but I was thinking that my next buy would be another dac/amp. From what I've read and seen I would be between the Chord Hugo or the Woo Audio WA7 firefly. I have read about how the Chord Mojo and Hugo pair amazingly with the 846s but I was wondering if anyone has heard them plugged to the Woo and what they experienced?
