Good price...what amp are you using it with?
Edit: Just FYI, each Muses01 is about about $34.40 street price. So with two is just shy of $70. So $150 with 2xMuses01 is actually quite decent pricing. Yes it's true VentureCraft probably got the OpAmps cheaper if they bought bulk, but still a nice thought .
I'm using a Fiio E11 and a PA2v2. I started with my headphones then got the DAC... Now it's time to start amp shopping.
