Just charged the unit after a year collecting dust and to my surprise no more skipping when using with my new iphone. Now driving my Z1r, I will put it bedside again 👍🏼

Good stuff! Does this mean that your previous smartphone was the issue?

I think so

Thanks, understood. If it's of any help, as output devices DACs rely on what they're getting from transports. If a DAC doesn't work as intended, the odds are a device prior to it has some issues, so it's worth checking it first. In the meantime, enjoy!

I am trying OPTical as an input but each time it says NO SIGNAL. Do you experience same issue ?

Right now I am sending optical to my DAC and output as Line out to 3.5 input of Monolith; difference between bitperfect via USB and analog input is massive and better on 3.5; it got so much space and separation that I couldn't believe it might

sometimes its as simple as not having optical connected in before you turn the unit on ....this unit can be fussy at times for some of the littlest reasons.

Hi fellow Monlprice THX Portable Headphone Amplifier owners! I need your help. Have any of you found a replacement battery on Aliexpress or Amazon that is a fit for the amp? My battery swelled and died, but I still love the amp enough to give it new life! Anyone found one?
