I'm still having a blast with mine - my audio chain: Mac Mini ('18) >> USB >> Modi 3 >> Vali 2
I was using the optical in the headphone jack from my MBP '15, but the newer Macs lost that feature, however, the Modi 3 has pretty excellent USB implementation.
The Vali 2 has a tube swapped from the stocker to an Electro Harmonix 6922 / E88CC (balanced).
I split my listening between my Sennheiser HD-6XX and some Edifier 1280T near field speakers here at my desk. I occasionally feed the Vali 2 the analog from a Teac P650 CD player (it has such a terrific DAC, I haven't gone optical with it).
Shameless plug: I kind of want to sell my HD-6XX for some closed cans, at this point I sort of want total isolation, or I'll just use my speakers.
I scored both my pieces of Schiit (no, it never gets old ...) as refurbs, so I'm into it, including the replacement tube __and__ some socket savers, for under $250. Astounding performance for that price!
I'm going to add a Loki - yes, an EQ - as soon as I see them on refurb again ($99, another steal).
