Agree completely - it depends on the variables in play.
My experience, for example. I have LCD-X (2021). I can play them on an iPhone dongle, the Qudelix-5K, or my Schiit Bifrost 2/64 + Lyr 3 stack. Does the sound from the Qudelix-5K suffice? In more passive/fun mode listening, for sure!
However, there is a resounding difference (read: improvement) in ALL parameters of sound quality when stepping up to the Schiit stack. The entire listening experience is taken up several notches.
Now, is that to say that the $1,200 price difference is completely justified? Yes and no - it’s in the eye of the beholder, folks. For me personally, I get a massive uptick in overall enjoyment, so it’s worth it (and I’m admittedly fortunate enough to afford it). For others, the 5K would be more than sufficient.
Would Quicksilver Audio fit the bill?
