These cables all make a difference. That doesn’t mean a good difference. AQ cables are really good on the right equipment. In my opinion you don’t throw AQ dragon on a streamer. Some cables are made for amps and some are made for sources. Their is even a sweet spot for preamps. I have tested a lot of this. The best power conditioner for the money is the Puritan PSM156 $2300 with their Ultimate XX power cable $925. If you try this you will buy it. I tried this on a whim coming from a $2000 20amp Furman. No matter what your music media choice is you will hear the difference and buy it. The Hifi store in the Chicagoland area will let you try before you buy. It does come with the Puritan Classic power cord unlike AQ which makes you buy it. A couple of concerns. Only 15 amp available, demo a burned in version due to it takes 12 days to burn in, 6 outlets, but they are totally separated in almost every aspect from one another. You can get a y adapter for each plug if you need more outlets. I recommend you put your TT with your phono stage or your DAC and Streamer together since they share cables anyways. Try before you buy. If I am full of it you have full permission to say I am full of it. Here is a store that lets you demo in your house or try before you buy: https://holmaudio.com/
I hope your local stores will let you try it. Also, When you borrow:
1. take a listen to three tracks without it
2. put the Puritan PSM156 in your system
3. take another listen with same tracks
4. 12 hours later listen again.
5. Pull Puritan PSM156 out
6. go buy Puritan so you are not sad 😩
