Echo Link

Forgive me learned peeps for asking such a basic question !
Has anyone any experience with the Amazon Echo Link ,to make use of their Amazon Unlimited music sub and improve the sound from an Alexa (which I love as a stand alone unit ,but hooked to my hi fi ,its underwelming ):(

I am not a big digital expert at all ,very green , as I tend to use cd and TT inputs ,but as I get older and more lazy :eyebrows: cooypled with the acess to music I can just play randomy and enjoy -get into by accident (which is great) , I had thought of putting the Echo through my small DAC ,but I am told the dac in the echo limits that first so no gain ?

The echo link looks the kiddie for me ,but wondered if anyone had any thought s and experiences !!
Thanks :)
