This is I guess the same as Tung Sol 5998, spectacular tube (although pricey nowadays), I can imagine it pairs with Atrium very well.
I hope to hear it at some point, I decided to move from zmf aeolus to atrium, but first need to sell aeolus
From what I read Atrium is more detailed than Aeoulus, more mid focused with more defined bass and a bit less treble energy. This is exaclty what want, would You say this is true comparison?
I am looking for a kind of super HD650, which I found aeolus not to be. Really easy to get lost with all those different opinions.... I also own VO and treble amount is just ok for me.
