Looking for advice, suggestions, or recommendations please - I've always been quite passionate but have only recently splurged just a little bit on improving my gear for PC audio; so focussing 100% on PC only here. Previously I had integrated onboard motherboard audio (Realtek ALC887), Logitech Z-5500 speakers, and various Sony IEMs that aren't worth mentioning. I used to have dedicated Sound Blaster PCI 7.1 audio cards but didn't bother to upgrade when motherboards went PCI Express only. As far as I know the Logitech speakers were pretty good back in the day compared to other PC speakers. Recently after reading a number of user reviews and written guides I purchased a Sound Blaster X7 (non-limited) DAC/Amp, E-MU XM7 passive speakers, and a Sennheiser HD 660 S. This is one of my bigger spends in a long time when it comes to audio so was wondering if I've made a good first step or a bad one? Any comments would be appreciated! I'm mostly into pop music and some wannabe-professional gaming and movies on the side. What gear should I look at next if I was to take this even further (in improving audio quality)?
