My Ragnarok is one week old and my Yggdrasil is 2 months plus old. I believe Rag is already burn in to 100 hours at Schiit manufacturing plant.
With a HD650 using 4 pin xlr balanced cable, the tone is majestic. Turning the volume to 1pm and at gain level 2, it is better than V-MAX sound. Forget 3D. Try 5D. Bass? Are you kidding? I have not heard HD650 belting out bass like a champ. My modified HD650 is transmitting all the musical notes with authority.
Whilst waiting for my balanced cable for HD800 to arrive and also waiting on the ZMF Eikon from Zach, I'm getting such a performance from my modified HD650, I wonder how much better it can get.
In balanced mode, the tone is full on with details and the clarity of an x-ray machine. I have not heard soundstage this wide and deep. It's even wider and deeper than La Figaro 339, which I also own and love. I have often praise the bass weight of La Figaro 339 but you should hear what Ragnarok can do. It does it effortlessly and with such authority.
If you are deciding on an end game setup, give the Yggdrasil and Ragnarok a listen with HD800 and HD650. Also Audeze LCD-2 or 3 or X. Also ZMK Atticus and Eikon. Hell, I would even hunt down a good pair of HE-6 to try.
