Myself interpret a very good performance is not only the composition but
for sure the sound quality. If it is lifeless and or bright ,I consider this a failure
and avoid , Thst being said if you stream and are willing to spend sa6 $5 k
You can make even less then average recordings sound very respectable with the correct Ethernet cables ,highquality hub ,for sure a decent LPS at the router
and at least a $4-6k dac to truly make a significant difference ,
if not then you can buy decent digital filters that plug into the streamer from the hub
to improve the sound ,since digital is not grounded and Carrie’s noise house to house you absolutely have to start at square one of the weak links in the chain
for sure Never have a old separate router modem for starters .
I had and call your cable company a all in one ,I bought a Motorola 2802 I think the # is around #$230 it has a docsis 3.1 , much faster processor and buffer ,even your tv picture will improve . It’s use a decent after market Ethernet cable , at least $400
and your best at your end point Sablon from the U.K excellent for the $$.then go to Linesr tube audio great LPS power supply to your router , and comes with a great Dc cable , buy a low cost $200 Pangea sig mk2 awg14 power cord for the router.
LHY SW-8 Ethernet hub excellent value for $600 buy the same Pangea power cord ,then there are several Ethernet filters , this is a economical setup ,a major upgrade at least a $3500 Ethernet hub to complement everything else mentioned
only then wil you hear a much more musical analog streaming playback .and your dac needs to be respectable as well as streamer . Just like a good turntable
your talking at least $12-$15 k to get a nice setup .it takes time but essential to remove every weak link in the audio chain.
