There may be other options but this thread is about modems.

You are free to spend like there is no tomorrow.

I've been curious about the Synergistic Research Network Router UEF here. 

Although it's nice to have more options sometimes this hobby uncomfortably tugs at the wallet

DX Engineering ISO-PLUS Ethernet RF Filters DXE-ISO-PLUS-2 is this interesting?

I bought the motorola 8702 which has docsis 3.1 it’s faster has a bigger buffer, 

what’s very important is that junk $5 wall wart ,you need a linear power supply 

I bought on Audiogon the Linear Tube Audio LPS and its excellent much cleaner sounding and much more musical with all the noise removed.

most modern rough terms are around 4 amp , this LPS can go as high as 8 amp 

and comes with a excellent DC cable going to the router most charge $150,and 

buy a decent power cord like the Pangea  sig mk2 awg14

  for $700 it beats anything under $1200

and also gives a better picture too to the tv Roku  which I like better with voice commands , Qobuz sounds much better .

and buy a quality Ethernet hub and cables
