After having most of the Hifiman headphones, I just got around to trying the HE-400. I did the same mods to the 400 that I had done to the HE-4. I replaced the grill with a light wire grid from a basket, I installed shelf liner over the ear side of the driver, and used Focus Pads and a DHC SP V2 Litz cable. Results are stunning, and very close to my modded HE-6. Fantastic mids, smooth treble, textured bass, very balanced throughout. I never would have thunked it. The HE-4 is a nice little brother to the HE-6, but I think with the mods to the HE-400, that I have another in the family that really out performs for it's price. The HE-400 on my setup is surprisingly a good all rounder.
I had the same result. Out of speaker taps, modded exactly like my HE-6, it's really close and that bass...............
This can scales nicely.
I have both of my Denon's set up with speaker taps, all three Hifiman's, HE-6, HE-4 and HE-400 all sound very good out of the Denon's, from Metrum Octave MKII DAC. But the Kenzie Amp brings the magic of tubes and delivers 3 - 4 wpc, which is plenty for any of my orthos to outperform the Denon's at 110 wpc and 125 wpc. The Kenzie produces voices and instruments out of a clean black background, that just seem to appear out of nowhere!
