Looking for headphone amp/DAC

Never heard the Z Dac but have owned an iFi Stereo 50  & can attest to them making a highly musical DAC with a super low noise floor that can really dig detail out without being harsh.For $150.00 I doubt you will find many that compete & certainly none that better it..

Thanks for your response. All the reviews are good

I prefer my Audioquest DragonFly Black (with Jitterbug) before my iFi nano. If you can go up in price the DragonFly Red is probably even better.
