When did this become a budget hifi forum? You want value? Buy mass market gear and it will get you about 50% there. Seeking quantity over quality go for the $300 turntables and hit the used record stores. Your raspberry NUC streamer and an $800 DAC with Amazon music should get you the same sound quality. Enjoy. Those seeking something more in sound understand that it will cost more. Each step up in sound costs quite a bit more. It's like any hobby- climbing to the top requires perseverance, stamina and a strong bank account.
Many of the detractors here have little to no digital audio experience. They talk about network switches as if they have tried them all in a top tier stereo system but in reality they have no first hand experience and have only read the opinions of others, then they pick and choose the opinions they like. That is neither good science nor good engineering. The IT crowd are the worse for opinions about audio. Engineers can and do have strong opinions about their products but more often than not test results leave them baffled and they are forced to rethink their theories. That leads to growth.
I've seen a majority of people here on these forums experience positive results with audio grade network switches. That's why I finally gave it a try myself and also had positive experiences. Sure, a few didn't experience positive results but to dismiss the experience of the majority is well, denying reality.
