Streaming, Getting the Signal, Then What?

Welcome to the rabbit hole of streaming. At least ten years into streaming, experimenting with so many devices and it continues to this day. In general, every single link in chain important, noise introduced at any point in chain is a loss one can never get back, clocking equally important. So, it begins with internet provider/speed (stability here) all the way through dac. As for guiding one as to specific solutions, look at all the advice given in this short thread, I'm sure much more to come. So many devices, so many opinions, where does one begin! I've gone down the road of experiential learning, some fails, some wins, still learning. Most recent experimentation is attempting to determine what is best input for dac, usb or I2S, I fully expect a unique outcome based on what dac used. Unique implementation of common technologies is replete in streaming and it goes on and on.

The AirLens is dumb. You cannot play via a remote app like most of us. No USB drive play. I cannot think of a worse choice for a first streamer.

It is built for DLNA. Good luck with that.

I don’t know what you want to do but it might be impossible as dreamed up.

Wow! I cannot believe how quickly my OP went off topic. No, I am not changing my "stupid" AirLens.  And no, at this point, my DirectStream DAC MK1 is not "on the chopping block."  I could not have been more clear in my OP, that the equipment I have is the equipment relevant to this discussion. 

Go take that discussion elsewhere please. 

I appreciate audioman58 starting in the right direction mentioning Motorola 8702 and LHY SW-8 switch.  Please stay on OP topic. Greatly appreciated. 

And to zlone, excellent point - no, there's nothing in my current setup that bothers me - nothing. I am just exploring a potential step up allowing my ISP signal to be possibly better than what I am experiencing through my current Netgear Nighthawk CAX80 modem/router device. 

Good test for quality of streaming chain. Streaming sound quality should be at least equal to cd's played over quality transport.

I feel so stupid not getting the streaming thing though at almost 70 years old I have moved more toward digital then any time previously.

At age 70, hearing quality dissipates and the ear lobes could start turning into cauliflowers. So, maximize the bang 4 buck on components and give the spare change to your struggling grandson instead.

Streamer: Wiim Ultra.

Price is around 300 bucks, very feature rich (full peq and some room correction, if needed), has a very polished easy to use user interface for senior citizens. It could sound very good on its own, but, if you insist on a external dac, it offers a USB out as well so the dac doesn’t depend on any timing from the streamer.

Externl Dac: Schiit Bifrost

Price is around 800 bucks. Run this great R2R dac in NOS mode and it’s all you may ever need.
