I run analog through a Project Debut>iPhono2>Yamaha R-S202>Tannoy Mercury 7.2 speakers at home and enjoy the sound. At work I'm running a Fiios X3>Topping D30>Yamaha R-S202>Polk Audio RTI A3 and it it sounds thin by comparison. The more I read about analog vs digital I'm wondering if the difference I'm hearing is just compression or maybe a product of the space being too small for the speakers. I was considering trying a tube amp but would that add depth or just warmth?
