Finally, DNA Stratus in the house.
I only got to listen to the Stratus once at a small meet many years ago, before the first major update (choke upgrade) was implemented in mid-2013. This Stratus not only has the choke upgrade but also the latest 2017 updates which supposedly provides a higher level of transparency, blacker background, deeper soundstage at a small expense of DNA's signature liquidity/warmth/tube bloom.
I haven't heard the Stellaris, but so far, the Stratus is the best amp I've heard to date with my modded HD800. I'm currently driving it out of the TRS output but a balanced cable is on its way. I heard that there isn't a lot of difference between SE and BAL outputs, but I already prefer it to K1000 driven balanced. The Stratus is great with K1000 too (as it was originally designed with the K1000 in mind), but the HD800 is what makes the Stratus truly shine IMO.
Speaking of K1000, I found it rather strange that I could not find one single image of a Stratus/K1000 setup online, considering the Stratus is sort of meant for K1000 and many people own this combo. So here you ago.
