It's my DIY work, CNC and 3D printing process are needed. I'm willing to share the CAD file for the case of DTR-1+ and SG-1, please send me the email address if you are interested.

The sound would not improve, but the long distance connection would be more stable.

I'd like to show you my moded SG-1，nothing changed on the circuit，I just replaced the aluminum case with other materials. The front is hammertone copper plate, back is carbon plate, and the frame is 3D printing SUS 304. the bluetooth signal would be blocked by the new case, so a new +9db antenna...

I think DTR-1+ and HM901s are in the same level, in fact I've heard the rumor that the founder of Dethonray is the former engineer from HM, that may be why they share similar high voltage power supply solution. SG1 have the similar circuit structure as the DTR-1+, and maybe the 90% of DTR-1+ in...

I have the DTR-1+ and very satisfied with the sound quality, so I got the confidence to pre order SG-1 right after they released it, the sound quality is quite close to DTR-1+, but the convenience of BT make it took the place of DTR-1+ in my backpack. I‘ve made the protection case for it, the...

If there would be a new product in the size of E02i, but with dac function, that would be more convenient for phone users.

Quote: since the E18 is for android, would FIIO issue a apk to enable the other android phones to use this DAC.   I have tried USB AUDIO RECORDER PRO on my HUAWEI D1 XL, which works fine with my microdac, it would be great if FIIO can issue a driver or player apk with similar...

I have the T3,ER4S,ER4B T3 can't drive the ER4S/B well, the output is not powerful enough for the Ety

Hi Headphone addict I'm currently using a RME digiface for optical out, to a Headroom Micro Dac, I wonder if the line out SQ of D10 is better than MicroDac thanks

hope they"ll issue headphones outstanding both in sound quality and appearance

so cute!!!!!
