@axeis1 I don't think I mentioned that I did test the filters. Chord is the brand I am most familiar with so I tested them quickly in this setup but found I liked it best with the filters off. This is not a particularly bright setup and I find the TT2 filters add a touch of warmth in high frequencies, that is it. They are more subtle than say NOS vs linear on the Wavelight.
I rarely use the Chord filters with either system as both have tubes or my headphones that I use most commonly (Thinksound On1 and Focal Celestee). On the rare occasion that I have a demo of another headphone, that may change. I would have the filter on warmest with say Focal Utopias. Probably off for Stellias. You get the idea. Headphones have been hard to keep in stock and I can't open a pair for demo.
