I jumped around with these today on my amps. My system is now wired as:
-
BF2 to XLR switcher to Violectric V220, Monoprice LP and iFi Pro iCAN.
-
BF2 to Schiit Loki to RCA switcher to Violectric V220, Monoprice LP and iFi Pro iCAN. EQ usually causes a raising of the volume.
On the XLR front, the Pro iCAN (using X-bass and 3D) is awesome! A wide stage, great separation, great mids and great bass. Worked very well with rock, blues and horn jazz. I couldn’t ask for more, especially at this price.
The LP is Very strong with these headphones (4.21W). I think it is missing only the X-bass and 3D, obviously. I love the sound of this amp as it is lush and smooth. Just missing the extra effects (which are fixed later). If the iFi is a 10, this is a 8.5-9.
Last is the Vio V220. It struggles with these. The sound is thin with high gain and volume at 1:00-2:00. It needs more punch and power to compete. That comes later.
I would recommend the top two amps with these headphones for a lot of fun.
Now, using the SE inputs. This surprised me.
With the iFi, it offered a different sound and is obviously more flexible with the EQ option. The big upside would be if you needed to pull the mids forward, add some bump or turn down the treble. Didn’t do a lot for me.
One oddity about the LP is that the inputs, XLR and RCA, are equal, power wise due to its wiring. However going via RCA brings the boom and the extra bump from the Loki. This amp comes Very close to the iFi with this addition. Very full sound, nice and bassy with Lots of power. FUN!
Lastly, the Violectric V220. This amp LOVES the Loki. It gives more boom, more impact and more volume. This combo works. It is still number 3 in this group, but it works well. I love the fact that this amp can fill out some of my headphones (Grado, etc.) nicely. But it is really not meant for HUNGRY headphones. Workable with the Loki and awesome with regular headphones.
End result with the HE6se V2’s is:
- iFi Pro iCAN = Awesome!
- Monoprice LP = Just down a step.
- Violectric = Not meant for these kinds of 'phones. Of course V280 and V281 are probably quite different from mine.
