Does anyone have issues with keeping a stable USB connection with their Q5S? I didn't right away when I got it but it has almost gotten worse over time. I thought it was my cable so I bought the Fiio USB-C cable https://www.amazon.com/Fiio-CL06-Type-Micro-Cable/dp/B07DLQ2XYZ and it arrived over the weekend and it seems almost worse. I can't pick up my phone and amp at all or it loses connection. It is very annoying. Almost worried it is the AM3D amp module USB-C connection. Going to try comparing it to me Q5 this evening and see if I still have the issue.

Never had such issue and I've been using it with Android phone with Fioo otg cable and 2 different usb cables when connected to Win10 PC (directly or in pc->iusb3.0->Q5s chain). As a side note: I do not have AM3D module, only stock one.

I have similar problem. In the beginning USB connection was stable with ML-06 to my Samsung S7 but last months it interrupts during movement when walking outside. It works perfectly when nothing moves but if cable moves in connector by touching something interrupt appears and playback stops. But the interrupt is not so long and connection is still working and pressing play again is enough. But sometimes happens also that connection is completely lost in Android and I have to manually reconnect cable.
I don't use Q5s so often - maybe max 3 hours every 3rd day. I don't remember that ever happened with my old Q1 M2 (but it had different problems :frowning2: )

I have just tried it (never used line-in before) and yes - output power is very low when line-in used. Really very low - like no amplification, maybe lower than input. Looks like we found another common problem. @FiiO can you tell us what to do with this? Is it bug or feature that it does not amplify?

I think just so works the device mates. No problem with it, just is great DAC and not so great as amp only.

I dont have Q5s, but Q5 only yes, and few months ago i asked if its normal to have (i would not say weak because still better than regular phones or PCs, but anything above 32ohms seems to be too much for it) even with the AM5 module. Other guys are saying its normal (in the other topic for Q5) as well and they experience the same thing. Its just made to be used mainly as DAC thro USB or with Bluetooth. Their old amplifier E12A gets 2x louder easily with the line in used (which by specs is around the same as their AM5 module or the stock module balanced). I was surprised back then as well.

Don't forget coax. Currently I'm using coax and the sound is fine as with usb.:smile_phones:

Dear user,

Are you using the headphone out when having line in input for the Q5s?
The output level of headphone port for reference:

Are you comparing with the usb input?

Best regards

Samsung S7 was always at MAX volume, all comparing was with the same IEMs KZ ZS7 with SE cable to both S7 and Q5s SE 3.5mm headphone output.
I compared USB in vs. Line in - Line in a little lower volume, max. 20 degrees on the volume knob.
When comparing volume of S7 (headphones directly to S7) with Q5s (Line-in connected to S7 max volume) - when Q5s volume knob was at max then sound level was a bit lower then headphones connected directly to S7.
So the output power seemed to be lower then S7 at least on my IEMs.
You have to check volume on the phone, it often lowers to around 2/3 when you connect something on headphone output for safety hearing. Then the output power is a lot lower.
I don't expect to use Q5s as amplifier only, it is a DAC for me, so no problem. But it is strange.

Someone using a holder posted a photo here some time ago. Inspired me to use it like this at my desk. Dissipates heat much better.

Very strange, the 3.5mm output on my Q5S has just stopped working, whilst the balanced 4.4mm output is working fine. I've tested multiple earphones now and I'm getting nothing from the 3.5mm jack.
Hello,

I got the email from you that your Q5s is working again now?

Best regards

Hi,

Thanks for getting back to me. Yes it seems to be working okay for the moment - it stopped functioning for a few hours the other day for no apparent reason and suddenly started working again in the evening (which is when I sent an email to you).

Cheers,
Tim
