Its ok when just music is playing but if i use the phone for anything else (which I usually do) it is unbearable. I am surprised I haven't heard of this issue if its common. Anyone else have this problem? :(
I don't have the Leckerton yet, but I have several other portable units (iBasso D-Zero, iBasso D6, ODAC/O2, Meier PCSTEP, Apex Glacier) and they ALL have interference issues with cellphones (I'm using a Verizon 4GLTE device). It seems like turning off Bluetooth helps, but it's still there. When I listen while driving long distances (as I did yesterday), I use a retractable USB cable to separate the phone and amp as much as possible, which also helps.
It seems like this might be at least helped by putting some type of shielding between the phone and the DAC/amp. Has anybody tried this?
EDIT: this is a company that produces a number of different types of EMI/RFI shielding, and since they allow you to register for free samples, I've signed up and will hopefully be able to test some of these out. The frequencies Verizon uses at the moment are 700/850/1900 MHz, so we'll see if this helps the interference or diminishes reception. Anybody with helpful information here would be appreciated! :)
