Which filter? :D
The night of pink noise did it for me (cumulating around 60 hours of both playing music and letting pink noise at night), the sound is just "popping" open and now I understand people saying they have a wide and deep soundstage (wow, you *forget* that your wear an IEM it's really a strange experience).
In the market for a good low impedance amp : has anyone tested this with FiiO E18 or VModa Vamp Verza ?
(Sony PHA-2 is tempting but specs are nowhere to be seen in terms of output impedance. Or maybe Sony NSW-ZX1 but same issue : no spec for output impedance...).
I have read iPod touch 5ht gen is the best DAP match for some but any suggestion for a good matching amp?
That would be Brown Noise (literaly from color prespectives)
The brown note is a hypothetical infrasonic frequency that would cause humans to lose control of their bowels due to resonance. Attempts to demonstrate the existence of a "brown note" using sound waves transmitted through air have failed.
I confirm that the DX50 works very well with the 846s.
Read iBasso DX50 has very low OI (<0.5)
I have auditioned the SE846 with the iPod Touch 5G (0.75 OI) at the Apple Store for an hour and it's a very convincing combo indeed, my E18 (<0.3 OI) is shipped we'll see how it fares with the SE846 in a couple of days!
I have the DX50 as well. I forgot my mini-mini cable today, so was forced to use the HO instead of my Shadow. There was some audible hiss with my 846, on low gain setting, with the least amount of hiss showing through on the high gain setting. There was also a clicking noise that wasn't super loud, but I could hear it during quiet transitions in music, as well as when there was no track playing. Not sure what that might be, but the LO > amp definitely sounds better than the built in amp.
The 846 isn't a reactive dynamic driver. BAs by design have inline impedance to achieve the curve that is aimed for. For example the Ety BAs are 9ohm with either 18 or 91ohm inline resistors to extend the treble.
The concern with high impedance is changing the frequency curve not control. In the case of the 846 the impedance curve tracks the standard filter pretty well. An increase in impedance will boost sub bass and upper treble. Not a terrible thing for on the go usage. Worse case you pop in the bright filter and the DAP boosts the bass back up. The treble boost isn't worth considering since even if it double it would be inaudible.
