I don't have that kind of budget unfortunatelyBluetooth Signal problems also depend on exactly where the devices are. For example, Since Water absorbs Bluetooth signals, if you have phone in your hip pocket, and the bluetooth receiver in your breast pocket, you are more likely to have signal loss even at a short distance. (i.e. The devices are not in line of sight, and have a lot of water/solids between them. A room full of people between you and the transmitter also reduces range for the same reason. Bluetooth also drops if you are behind a refrigerator, or metal filing cabinets, Steeel Reinforced Concrete wall, etc. Also if the bluetooth antenna on either transmitter or receiver, is flat and facing a metal desk, then the bluetooth signal may get absorbed by the metal desk; "Standing" them on edge can help prevent that problem.
The Q5K has better bluetooth range. To me, the R3 Pro Sounds better/warmer (gives a bit more/better but still neutral bass ) when both are used as a wired dac/amp. PEQ on the Q5K should be able to correct that... My 5K is the original and it's a different dac/amp than what Qudilex puts in the newer 5K's. So things could be different than my experience.
20 Years ago, both would have been considered great sounding; And for entry level portable devices they do sound great. But neither will be as good as a mid-fi $400 to $500 DAP. Neither is a bad choice for "on the go".
I am using FiiO X3II right now but it has usb problems that cannot be fixed(sent it to FiiO 2 times). I guess both Hiby and Q5K would be an upgrade.
Thanks for the help
