I think this stack will be quite easy to reference as many people have the same stack.
I have been experimenting for some time. This stack is amazing and very very good with planars, but please get something that can show its full capacity, especially the dynamics and timbre. I watched those youtube reviewers, and I don't feel they explained fully the strengths of both Jot 2 and Bifrost 2. Especially the Jot 2. They mostly cover the obvious sound traits, but not the more delicate ones, which the other amps they compared with fall flat on their face compared to Jot 2.
Sundara, Ananda, Arya wont be able to show its micro dynamics well. They all sound good, and tonally a match. But you won't see what the stack is capable of. When you compare with better pairings, then you will see how very flat they are. Timbre also suffers. If you only care about details and clarity, then the Sundara is fine. I don't have any Audeze with me at the moment. I wish I do. I can imagine the new LCD-X would be a good pairing. At the very least, the Audeze should have better macro dynamics.
The best I tried so far are the old hifimans and Verum One. I really don't want to promote Verum much, but it is a dream match. Very lively and full. No contest. Give it a try if you already have (or can borrow) one. If you have HE-500, HE-400, HE-6, give them a try too. HE-400 and HE-500 need the fuzzor mod to improve their clarity. Goodness, they are really good. I don't have the HE-6 with me right now, but I think it could be an amazing match. These headphones sing with this stack, showing the full spectrum of the music.
Another headphone that you should consider are the Focals. Boy, they sound really great with this stack as well. Everything is there. Very lovely sound.
