Digital audio and streaming is the fastest changing aspect of this hobby.
Not all manufacturers will keep up…or even want to! They would rather sell you the latest Mk2 version…..🙂
Please explain/elaborate how streaming has changed in the last few years?
The only real change/addition to streaming technology I can think of is the addition of MQA, anno 2014. This is not a defacto implementation and requires a licensed product to unfold completely. Very good it can be too but that's an entirely other story.
What we really need in this country (UK) are better pipes for supplying (real) high speed networking and broadband rather than the mieserly ones which all to often are still so prevelant.
I use two active powered products which include streaming and DAC technology. One was originally launched 5 years ago, then my MK2 'superseded' it a year or so ago (they sound mostly the same, I tried before having committed myself). The other is some three years old since inception.
Neither one is outdated and I wouldn't expect them to be for a long time to come.
DAC's are released at a rate I change my underwear. We have long passed the audible limit of what is humanly perceptible, years ago. Its about paper specs now, no more. This and the fact many prefer very specific implementations ... and not always the newest ones. I am simplifying this but hopefully you get the gist ... .
Will they be leading edge in ten years? No, at least not from a DAC perspective but quite frankly I don't care as the benefits of such systems are so numerous and outweigh (for me) any unknown disadvantages somewhere far down the road. That plus they will still function perfectly.
Nothing wrong with the legacy separates route. I've done it myself and currently thinking of a third small passive system but if you have not used a decent active one made for home purpose (I don't think much of Studio stuff for home listening) you have done yourself a disfavour.
I rest my case, the sun is out and I have more interesting things to do
