Just curious, what have you compared the X7+ Sparkos with?eBay or send the owner an email from his website.
X7 needs 4 opamps total:
ss3602 x2
ss3601 x2
Sound is absolutely phenomenal after the upgrade. It’s an investment but if you want the absolute best for gaming/hi res audio all in one, its the best way to go. It’s sound rivals some of my more expensive equipment.
