I'll second the MyDac. I will likely be putting mine up for sale soon as I no longer have an office system so it's just resting in a box. It's a great unit and a fabulous bargain IMO.
Budget DAC recommendation for Office system
I have converted one of our bedrooms into an office and putting in a modest system. I currently have an AppleTV connected to a TV for the musical purpose of streaming Tidal. I am taking the optical output from the TV into an old Fosgate FAP-T1+ to act as a DAC into a refurbished Hartman Kardon 770 receiver that drives a pair of Onix Rocket RS150 speakers or Green Mountain Euopas. The Fosgate is too big and runs pretty warm . I am looking to replace that with a decent budget DAC. I am thinking about a Schiit Modi 3+, the new Modi e or maybe a used Musical Fidelity V-90 DAC. I have high end systems in other rooms of the house so just looking for something decent here.
I welcome comments and alternate suggestions
