Like to tweak my system


I'm fairly new here and just learning.  I have a Yamaha R803 and Vandersteen model 1s.  I stream Spotify. I'm happy with that for now but I'd like to improve the sound in other ways if possible. I previously asked about better speaker wire. Perhaps a power conditioner, DAC, amarra software, a better power strip?  Any recommendations would be greatly appreciated. BTW, as recommended here I purchased Jim Smith's book, great advice, thanks.  Doug

That's good advice, thanks. I have an audiophile friend who told me that over the years he probably spent $50k on stereo equipment by buying, selling, trading, upgrading, etc. He said if he could start all over today, he could put together an equal system for about $10K.  He had fun and has no real regrets but the advice he passed on to me was.... take your time, learn first, then choose wisely.  I have a nice system now (Yamaha & Vandersteens) but have felt tempted to upgrade when I see better equipment but so far managed to hold off and keep learning. Usually the next day I'm a bit relieved. I'm sure I'll upgrade at some point but hopefully I'll do it smart.  Although that little MAC MA252 has been calling my name!
A quality recording on CD will greatly surpass the sonics one gets from Spotify. I use Spotify for finding new music to purchase, playback is accomplished via transport or computer file derived from CD.  
+1 for Jim Smith's book. 
Get your setup dialed in.
Do room treatment.
You now have done half (or more) of the battle.
Now focus on better gear.
