Spotify streaming from pc


I need a little advice and or reassurance here.  I am streaming Spotify Family Plan Premium from my pc, via ethernet cable (due to distance), to my Oppo Sonica DAC which feeds my integrated amp and speakers in my listening room.  I have the Sonica app downloaded on an iPad, on which I can control what is being played, however, I have no audio quality adjustments available on the iPad/app.  It sounds okay, however, not nearly as good as Tidal and I am also not able to make any sound quality adjustments on the Spotify website at the pc either - as I could with Tidal.  Do I need the Spotify app on the main pc or not?  Is this just the way it is going to work or am I even doing this correctly?  This is the way I stream Tidal and it sounds great!!  Thanks for all help and advice!

Good IMO that you downloaded the Spotify app and now have the ability to make some adjustments for streaming. Also, IMO, the biggest and easiest thing you can do to instantly maximize sound quality with the app is to engage "loudness normalization" or whatever it might be called within Spotify. 

That is my experience with Amazon HD in any event for what it's worth. I believe that most of the streaming services are simply "loud" if left unadjusted in this sense. Yes, you can probably tweak away with volume controls within Windows or your DAC driver, but it will be endlessly more complicated and probably take forever to figure it out and dial it in. 

Think of "loudness normalization" as being akin to setting a new TV on Cinema Mode once it arrives home; it will probably get you 80-90% there (maybe more) instantly vs. endlessly tweaking individual settings. 

I probably screwed around with various settings in my PC for 6-8 months before someone suggesting loudness normalization on another forum. It was very worthwhile, even though it might be counterintuitive from the typical audiophile point of view.

Thanks hdm and henry00.

I gave up using the horridly frustrating and unsupported Sonica streaming app and bought a Bluesound Node. Holy crap I didn't realize streaming was supposed to be this easy LOL.  I still use the DAC in the Sonica because it sounds better (to me) than the Node DAC.

320kbps is the highest streaming quality you can get from Spotify. You may want to try adjusting the bitrate, sample rate, audio channels etc. of Spotify songs with the assistance of AudFree Spotify Music Converter. Apart from this, you will also download high quality Spotify music for free.
