Heya,
How about a nearly 1 year update...
Just an update on further modifications to my HE500 that I've had done. And a few better images of the other headphones that I've had permanently recabled as well. Everything now has detachable locking mini-XLR terminations, or ear-rings, and terminates to normal 4 pin XLR for use with speaker taps or with any adapter I choose. Completely universal. All being driven with the Emotiva at this point (the Denon D5000 uses the 500ohm resistor adapter of course). No more hifiman terminals (hate those things, they screw on, and are too easy to bust/mess up if you change the cable often).
Brian at BTG Audio did all my work, including converting the Hifiman to mini-XLR instead of the Hifiman terminals.
DT770 premium 600ohm.
Denon D5000
As for an update on the Emotiva itself. It's still holding up very strong, no thermal issues, it has gone through a move to another house, survived every bump so far and all the abuse I put on it.
We are getting close to the
one year mark on this thread by the way. So my update is based on literally a year of use of the Emotiva as a speaker amp for all these headphones. My basic update at this point, is that I've tried using some of my other amplifiers, including my tube amps for some of these, and at the end of the day, I'm always back on the Emotiva. It literally sounds cleaner, crisper, blacker, and has more meat and the sound stage is just better to my ears. One year later, still no hiss or hum on any of my headphones (caveat, my Denon uses a 500ohm resistor adapter). The knob is still nice and tight, it has not loosened up. A year later, the Emotiva sounds pretty much the same as my poor faulty memory remembers from pretty much the first day of having it. I have not noticed any significant changes in any of the frequency spectrum from the Emotiva. Also the use of the 500ohm resistor has not caused any weird anomalies or damage that I can tell so far, a year later to the amplifier.
Also, I have run some bookshelf speakers with the Emotiva, and it really pumps out the juice. It finally gets hot when pushing speakers at high volume. I've never even felt it get warm hardly with headphones. Speakers sound superb on this amplifier. So double-duty is golden. I was mainly testing some entry speakers for fun, like Polk Monitor 40's, 50's and even tried the 70's that I have, did well even on the 70's, but 50 watts is a limiting factor when you get that many large woofers in one cabinet. Regardless, this amp is still pushing strong.
Very best,
