I don't know what to think.
My first two days, I liked what I heard. BUT, I was getting 15 to 20 seconds of dropouts for every minute of playing time.
On my third day I listened for about 45 minutes straight without one dropout. But then the dropouts started again for the next ten minutes or so, then I shut it off. I haven't tried it today.
I'm using a Galaxy Note 4 with an OTG cable into a NuForce uDAC2 into a pair of Sony MDR-1RBT. The Note 4 is 802.11AC compliant and my WiFi is from an Asus RT-68ACU router, also 802.11AC. I have a 75meg FiOS service and around my house Speed Test says I get 85meg on my phone. Low would be around 60meg.
During that 45 minute stretch yesterday, I tried my Jaybird Bluetooth APTx adapter plugged into the headphone out of the uDAC2. At first it was very distorted until I realized I was over driving the input of the Jaybird. After turning down the volume on the uDAC2 and raising the volume on the Sonys the distortion was gone and I was getting impressed until the dropouts started again.
In a perfect world:
1. The dropouts would be gone.
2. TIDAL would work with my USB Audio Player Pro on my Note 4.
3. My headphones were APTx.
BTW, I'm very familiar with the best recordings of the best songs of Boz Scaggs, The Eagles, Sting and Santana. But those particular cuts, were for the most part, missing, despite a rather sizable collection of each.
