Improving on the stream of a combined streamer dac


I recently (foolishly) compared the streamed sound of my Electrocompanient

ECM 1 Mk II to internally stored digital downloads on the same ( ie not stored in my Small Green Computer server).  I was surprised how much better the downloaded files sounded.  Perhaps, I was naive to think otherwise.  So, I started looking at old audiogon threads to see if I could figure a quick and easy fix to up the sound of the streamer but found little that made sense or was affordable.  My question is whether I should continue to search, or if I should take it for what its worth and just listen to the music.  The rest of my digital front end:  Small Green computer server,  a Trendnet unmanaged switch and the ECM.  I use a Luna Orange ethernet cable from switch to ECM and a Purist Audio cable to the SGC.  Thanks for your advice and happy holidays to all.

The new Starlight 10 Twinax is active full bodied and warm sounding. I never tried the older WW Ethernet cables. 

A good linear power supply from the router,that $5 wall wart just adds loose,

then a decent Ethernet hub, LHY 6 is a great value , then quality usb, Ethernet cables , Tubulus audio make very good ones for the $$ 

Has anyone tried Silver ethernet cables?

Yes, I use the Signature OCC silver cables from Audio Sensibility. Right or wrong, I like pure silver for digital transmission. WireWorld seems to agree and uses it in their best digital cables. I have their silver USB and it is excellent. Anyway, I have not done a lot of comparisons of Ethernet cables, kinda just checking a box with the  ones that I have. I would like to try the WW version, but it is pretty spendy.
