just how relevant is a stand alone DAC in developing the digital signal anymore?
I think the issue is one of control, and upgrades.
I mean, if you find an all in one you like, you should absolutely buy it. Fewer parts, smaller, fewer cables. Especially in small apartments, bedrooms.
However, my current set up is a Raspberry Pi -> Mytek Brooklyn -> Luxman 507ux Integrated. Retail is a modest $8k or so, but still not money I'd like to shuffle or attempt to sell used and buy something else.
Let's say I don't like the wireless user interface (UI) , no problem. Install something different on the Pi, or get a streamer with built in storage I like. Problem solved. My sound quality remains the same.
Lets say I want to upgrade my DAC to a Manhattan. No problemo. The Luxman stays put. The streamer which has my music and a UI I like stays exactly the same.
Having said this, I pay for all the cables, gadgets and the ability to control exactly what each component is. I don't sweat that I paid several thousand dollars for the Luxman and might find a DAC I like better, which then causes me to throw it all away together.
So, reading what I just wrote, the amount of money you spend matters. If you can find an all in one for $150 and maybe in two years doesn't support your music store or goes out of business and no longer supports current iPhone/Android, well, throw it out and buy latest.
Best,
