Anthem STR or Lyngdorf TDAI 2170?

First if all, using splitter is not advisable and will degrade the sound quite a bit. Second of all, in general B&W does not pair well with a small powered tube integrated amp such as the Rogue Cronos ii cause your Cronos ii isn’t able to provide enough juice and your B&W need to be pushed and will need more power than your Cronos ii can provide in order to shine. Unless if it’s a high powered tube amp.

For your B&W 805 D3, I highly recommend the Naim Uniti Nova integrated, which is basically a digital streamer/DAC/integrated amp put in a single chassis. Retails for $7500 new. Has built-in Tidal streaming app. The Naim Uniti Nova is a single box solution and is highly musical sounding and will pair really well with your B&W 805 D3. I had the Nova paired with the B&W 805 D3 in my bedroom setup before and today I still have the Naim Uniti Nova but has traded in the 805 D3 for the Sonus Faber Olympica l bookshelf speakers.

The Naim Uniti Nova has lots of inputs : Ethernet, USB, XLR & RCA analog, DIN, coax digital, optical digital, HDMI.
It is an outstanding piece and the sound is very musical very refined very fluid and analog like and it paired really well with the B&W 805 D3. Do not get fooled by its power rating of only 80 wpc @ 8 ohms, the Nova is capable of handling low impedance loads. Eventhough it’s rated only at 80 wpc @ 8 ohms but it is a brute force and a very good clean quality current. The quality of the current that matters not the wattage. It uses a big oversized toroidal transformer linear power supply. Highly recommended!
The Naim Uniti Nova will sound better and more musical and more fluid and analog than the Anthem STR or the Lyngdorf. The Anthem & Lyngdorf have more powerful amplifications but overall the Naim is better more musical.

The Naim Uniti Nova has better digital streamer/DAC than the Anthem or the Lyngdorf. Naim is very well known for designing and making a digital music streamer/DAC. The only advantages that the Anthem STR & the Lyngdorf have is room correction.

"The only advantages that the Anthem STR & the Lyngdorf have is room correction."
This, IMO though, is the major advantage.  Room correction will make magnitudes of order greater and positive difference over any DAC or streamer changes.  It's not even close
My preference having had experience with both companies room correction would be the Lyngdorf.

Thanks for the recommendation! And just for clarification I meant a switch not a splitter but imaginably it’s still impacting output/quality.

I'll definitely dig in to the Nova a bit more but am still leaning toward something that can also offer room correction given the dynamics of my living room: hardwood floors with some carpet, big glass windows, not much depth, etc etc.

Any suggestions along those lines would also be massively appreciated. Based on the specs and chatter around both the Anthem and the Lyngdorf I’m wondering if one > the other given my needs: something with room correction that can have the dual purpose of music and home entertainment. 

The Lyngdorf 3400 is the way to go here. It has everything you need and is built to a higher specification. Just make sure you plan on staying 2 channel.
