Wow! Just got my pk1's in the mail. Incredible full sound for earbuds! I'm running them through a Hifiman EF2 and they sound like I'm listening to full size headphones. Can't wait to hear them after burn in!
I'm thinking about getting the he5- ef5 combo sometime early next year. My question is would a Musical Fidelity V-Dac be a good enough Dac for that combo or do I need a Dac that costs more than a grand?
