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?

I don't know how long they're on sale for, But now I need you to decide between the unison and the forte. I'm leaning towards the unison simply because my Yamaha A-S500 integrated is a class AB which may yield a little more grunt. And watts than the class d amp in the forte.

Apologizing in advance for my ignorance on digital. (I'm a 2 channel tube/ vinyl dinosaur) 

What is the best uncompressed source to play through this Martin Logan Unison device? Can I use my Pandora on my iPhone linked via blue tooth? (seems like I may need another box to receive this signal?)

I recall reading that the music played through the iPhone is compressed.  I hooked my iPhone into my ARC SP 15 and it sounded like crap. I assumed it was due to the audio being "clipped off at both ends"

I'm hoping somebody can give me understandable advice as I'm ignorant of the digital developments. 

That particular martin logan streamer does not have bluetooth. It operates by pairing both devices on the same.wifi network. I believe  streaming over wifi actually gives a better signal than bluetooth. There are other Bluetooth streamers like the Bluesound Node that have a bluetooth option to stream along  with wifi method but wifi streaming is always better I believe. Maybe others here can elaborate because I too am a dinosaur and not computer savy.

The DTS Play-Fi app works fine and they update it for free, here is a video about the app. It will show you how to play uncompressed and hi res files with the app. I think Tidal, Quboz and Amazon Music all off hi-rez streaming which works with the app:

@yesiam_a_pirate, I stream using spotify premium I don't think pandora has a high bit rate option for their music streams, But streaming services such as Tidal and Qobuz Offer uncompressed high resolution flac file music streams to choose from. Those are probably the best type of streaming options along with streaming uncompressed flac files from a network attached storage device such as your own hard drive that. Music has been ripped to in an uncompressed format.
