Once you move up the train, the Magni quickly gets overshadowed by it's bigger brothers. Asgard 2 should be pretty impressive, it already looks great on paper. The difference between Gungnir and Bifrost is quite audible and most DAC's have been a waste of money or a marginal upgrade in my experience after a certain point. I think smart shopping accounts for the hobby, not just how much money you spent. Thats why I do not like LCD-3 at all, I feel the difference is less than 10% between LCD-2 and 3 having spent an hour with one to myself. HD800 is the sonic successor to LCD-2 to me. If you make a hobby of buying amps (incredibly boring hobby lol), the LCD-2 will not bring you much joy.
Going from HDP to Lyr to NFB-15.1 to Mjolnir hasn't really net me a huge crazy butt ton amount of improvement. Before you slap me with the diminishing returns BS, keep in mind that even if it's a worse headphone objectively, like K701, HD650, or T1 which I've tried, those actually end up scaling way better than LCD-2. Perhaps that is a testament to the LCD-2's efficiency, but something is telling me that the recessed treble signature and midrange bloat somewhat neuters it's absolute transparency.
Regardless I think Schit pretty much dominates the LCD-2 amp-space right now. I feel somewhat sad as I've always been an RSA fanboy but the Schiit pricepoints for what I get are just too good and it's not like I'm made of money LOL. I mean for the price of an HR-2 I'm getting a fully balanced amp with a brushed aluminum case and two choices of outputs. (4-pin neutrik is way easier to deal with than dual 3-pins)
