Looking at grabbing a Spartan with the current sale. Anybody here match it up with an Opus #1? I searched the thread and didn't see anybody commenting on this combo, except that the Opus hisses with most EE offereings.
From Pinky's excellent Spartan-IV review (http://theheadphonelist.com/a-lean-mean-fighting-machine-a-review-of-the-empire-ears-spartan/):
"If your sense of fun lies in crystalline transparency, and high-res at an affordable price, the Opus#1 is my choice. It’s the best-sounding player I’ve heard under $600, and you can get it for almost half that! It’s less warm than the Opus#2, and much less warm than the i5. Of my DAPs, it has a marginally thinner sound, but *** me does it sound clear and detailed, with dynamics for days. There is also a refined, smooth quality. So no digititis. Spartan sounds like a true reference, detail monster. Yet even with Opus’ extra treble energy, this IEM never becomes fatiguing. Together they make a heavenly melody."
