Thank you. That encapsulates what I was trying to articulate while my Arya V3 is burning in. It’s not that the sound stage is so vast. It’s that every sound and every instrument is identifiable.

Well, I bit the bullet and ordered the V3. Got it Friday. Already it reminds me of when I first heard the HE-500. Not so much the soundstage, but the instrument separation with good bass right out of the box. I'm excited about how it will mature after a few hundred hours. And it's SO MUCH MORE...

Necroing, but just in case, yes. Fixed output of Da'ccord into Classic. The variable outputs on the Da'ccord are for plugging it directly into something for which you want the Da'ccord to control the volume. Also, to the best of my knowledge, no difference in USB and Optical input. It's all...

Fantastic review; thanks! Have you ever had the opportunity to hear the Jade 2?

Is it that, or more likely the two rings of the volume control getting slightly out of sync? For that matter, I perceive equal volume when the left channel is boosted a hair more than the right. I don't know if it's my ears, the internals of the E/90 energizer, or my pads. Although I did send mt...

I hope your ears are better than mine. This was my finding from 2015:

Indeed welcome, and let me add that the improved power supply yielded good results for some; I didn't hear any noticeable improvement. Then again, my 40+ year old ears were never golden and are rapidly approcahing the brass/tin boundary :)

  Where did you find the headband? I can only find the cushions.

  I predict you will not be disappointed. I moved to electrostats as the headphones I had were making my TMJ unbearable (wearing an HE-500 for 6 or so hours a day made it that sometimes I couldn't close my jaw until I "worked it loose). I've stayed for the sound. My only picayune complaint is...

  It's ongoing now per their website https://www.koss.com/promos/cyber-monday. I got mine for 30% off last year; glad I didn't wait!

  Personally, I use Centrance DACport LX (the version w/o the amp) with my Koss (at work) and I don't feel fatigue at all. I think the LX is an excellent overall DAC, although it is certainly north of $100 ($250 list, althoughI have seen it for around 200).

Reasonable once you have them, but are they worth triple the price (650 vs 2000)?

Ditto :)

Thank you, Sorrodje.
