Has anyone tried using the Bluetooth function with the LME op amps installed? I'm getting weird static/electrical frequency sounds only with the LME op amps when I activate Bluetooth. I don't get this with the OPA op amps or Sparkos op amps. I'm trying to figure out if I need to exchange my unit. I tried contacting my vendor, and they asked me if I wanted them to contact their Xduoo rep, and so I said yes.
A couple days later, I got a response from my vendor. The Xduoo rep said that they don't have any LME op amps available to test out (very weird, considering they're the company that makes it). The vendor then said an option is for me to return it to them (the vendor), so they (the vendor) can test it, but they said they don't know what that would achieve, because they don't have a reference to compare to it.
I would assume that the reference for comparison would be another XD05 Pro device that's in stock for A/B testing. I'm puzzled by the replies from both the Xduoo rep and vendor.
So at the moment, I would like to know if my device is specifically defective. If so, I would like to exchange it for a non-defective item.
I also made a previous post here about a noise floor that I detected from the XD05 Pro. Again, I don't know if this is universal with all XD05 Pro devices, or if it's just my specific device that has a noise floor when connected with an IEM. I tested it with both the Prestige LTD and Zero 2, and they both pick up the same noise floor. You can't really notice it if you're playing a song with consistent instrumentals, but you can notice it if you're playing more of a ballad with pauses in the vocals/instrumentals. The noise floor doesn't get any louder or quieter based on volume or gain setting. If you use Bluetooth, the noise floor is humming the whole time, so your ears will adjust to it as white noise, but if you're using a USB connection to link your IEM to the XD05 Pro, then the noise floor activates only after you press play on the audio, and then after you press pause on the audio, the noise floor will continue humming for about a second or two before it flicks out.
Gah, I appreciate your help. Due to the other problems I'm having with my particular XD05 Pro, it's hard to isolate the source of the problem.
Do you ever use your XD05 PRo on Turbo mode? I find that my particular device heats up really fast if I listen on Turbo mode.
