New guy here, haven't been to the site in a while.
Well, through the course of the past few days... I have read much of this thread!
I just bought a DFR with an Audioquest Golden Gate 1/8 to 1/8 for my MBP to Marshall (guitar amp maker) Woburn (speaker system). I got this set up on my MBP as stated in the DFR Manual. The sound initially was, OK. Not overly thrilled. I tried the headphones I have, ATH-M50x, I know, nothing fancy anyway, but same thing; not too thrilled.
This stuff was delivered on Saturday. As I prepped my Samsung S5 using the Audioquest Android cable, grabbing the DFR, and heading out for a 3 hour road trip with my son, 15 min in, he put his headphones on, 20 min in, I pulled the plug on the DFR with Android cable out of my S5 and plugged directly into the 1/8 jack of my vehicle from the 1/8 headphone jack of the S5 as we have been doing. The DFR sounded bad, intermittent pops, and low volume using Tidal HiFi. Huge disappointment. But I covered the why, here.... I need to decide what to do.
I will say this, having the DFR on my MBP, connected to my Marshall Woburn desktop speaker.. the more I listen, the more sweeter it sounds... if I keep the DFR, it's for this purpose alone. I probably have 12-14 hours of listening time in thus far, it's set up on my desk. It seems to get better sounding as time progresses... they are all new, the Marshall Woburn, the DFR, the Golden Gate cable....
