Hey Eiffel! Thank you the answer! I am just looking around on the market, cause I would love to improve somehow my setup, and I am looking after something new, that's why I wanted to install something between my BursonAudio Play! and Amiron to boost my listening experencies (and also gaming too) but seems like this is pointless cause Bang only amplify Spearkers and actually won't gonna make my much more superior, neither the Fun too, as I read from your explanation. Any good opamps (besides Burson own opamps) to maybe swap in-out to have other listening experencies? Anyone can suggest some? Or should I buy another DAC/AMP combo like Woo Audio Wa7 Fireflies 2nd Gen with the vacuum tube upgrade? Maybe different cans? Any suggestions for different but somehow similar (like wide and rich soundstage) headphone like Beyerdynamic ones?
