Thanks - sounds good! Ampwise I'm really satisfied with my Questyle CMA 600i. Ultra fast, transparent and precise, but not analytical, tons of power when used balanced. My problem is the internal DAC. Paired with the heddphone it doesn't open up the soundstage as I wish (and as I'm used to know from external sources). So, from many other reviews I got the impression it's a great dac but does the Bifrost offer a deep and wide sounstage too?
Certainly wide - on the HEDDphone that is no problem. Deep is maybe not the best strength of the HEDDphones, but it is a system thing. The Bifrost is an outstanding DAC period, and at the price just about unbeatable. If you like your amp, try the Bifrost - Schiit has a 15 day trial period so the risk is low.
