Finally!! a mid priced (affordable) MQA DAC

Audio Advisor does not have many of the Pro-Ject Box audio components. 

There are two Pro-Ject "Box" components I'm interested in. The new MQA dac and this all analog, simple preamp

Both are not available, as of yest, in the US :(

Check out Underwood HiFi. He had a good range of Project gear. I haven’t checked on the Project Box DAC specifically. I had been interested in the Project Box Preamp but ended up with a Schiit Freya instead.

There had been a pretty active Project Box user thread on HiFi Wigwam (UK-based, I believe).

The AudioQuest DragonFly Red is an inexpensive, MQA capable DAC. In the last few months, newly produced Reds come from the factory ready to "decode" MQA. Older versions of the Red can be updated by the owner. Not sure about MQA ability for the Gen 3 Dragonfly Black.

The Needle Doctor carries a wide selection of Pro-ject boxes. 

The Dragonfly Red is quite possibly the least expensive shot at MQA
and coupled with a Tidal subscription you truly get a new window into recorded music...it's for real and inexpensive what more can one want really...
