Wilson tiny tots

Buy a Marantz na7004 and connect the tv to it by optical input/output and then the RCA plugs from the marantz to your amp. They sell for around $300 on ebay used. People are selling them because streaming is no longer supported by people at marantz but the internal DAC sounds great and you can play music through the USB in front also if you want too. The problem with USB is that it takes 4 minutes to load which isn't the problem with the optical output.

If you want to take the optical out of your tv into a dac I would suggest spending 150 bucks on an ifi ipurifier. Optical from tv is pretty crappy and this will help clean it up for pretty cheap. Makes a definite audible difference in my setup. Your tiny tits will thank you. 

For TV audio isn't the first order of business a DAC that accepts eARC, not optical?

The NAD 3020D and related amps may be ideal.  Takes optical input, very small.

Only reason you buy a Wilson Audio speaker is you want to have  an audiophile experience not TV or movie experience but luckily there is a way to experience both in a fantastic way. You need to buy good integrated amplifier in your budget, a used one if your budget is tight. I can recommend Hegel 190 which is fantastic integrated with great internal DAC, you also buy a Bluesound Node as a digital server and you are in business. Bluesound Node has an EARC HDMI connection and you connect EARC to that you can hear TV output as well. Tot is very good for listening but you will be missing some base which can be achieved by adding a sub. Do not push the volume on TOTs, they are expensive to repair. Enjoy them, they are one of the best speakers money can buy.
