Old days & steamers vs newer stuff?


Given that there are a ton of variables depending on speakers and other equipment. What are the generalities in comparing? something like...

1) an old blusound node 2i with an ayre codex dac

2) lumin d2 for dac & streamer

3) node 2i with giselli labs dac

Basically,  I'm asking if you think expensive old dac and streamers (lumen, node, ayre codex) still beat out the newer cheaper stuff like denafrips ares, gishelli labs, etc.

I want to improve my setup, but I'm not sure if used older higher end stuff is better than newer mid end stuff.

Quality improvements over time can often yield a newer less expensive product that is superior to older high end items.

Whatcha think in this regard when it comes to dacs and streamers?

Newest tech one can afford, or highest end used stuff one can find?

One more thing, DTS Play-Fi whole house audio is da bomb. There have been many updates to the app since it first came out. I have products from Klipsch, Paradigm, Deftech, Martin Logan and Philips throughout the house. Most of them were purchased on sale like the Unison. If you are going to add additional rooms to your system let me know and I'll post some updates. 

@labguy

I saw you are leaning between the unison and the forte. If you get both you can use the unison with your yamaha amp and the forte in another room with a separate pair of speakers. Play-fi is designed similar to Sonos so you can use whole house. I own the Forte amp too and it sounds like Martin Logan speakers, HUGE soundstage. Here is my review:

@kota1 will spotify on my phone allow me to diectly connect to the unison like it's a wifi device/speaker, or do I have to use dts play fi to hear spotify on the unison?

@labguy , yes you can connect directly to the unison with spotify. Just open spotify and connect the same way you would with any other device, no need to open the playfi app.
