Hi @FiiO,

No. Still it is crackling like every 40 seconds with the 96kHz.
It's fine with the 88.2kHz.
Do I need RMA?

Thanks,

Dear friend,

What's the format of the music you are playing? Other input would not have the same issue with the same music files?

Best regards

Hi KopaneDePooj,

Thank you for the welcome and help.

I would normally use the 3.5mm line-in just with my Astro MixAmp TR Pro when gaming on PS4. The MixAmp does not have enough power to drive better headphones without a headphone amp. I know it is not ideal but sounds still way better than using normal headset with just MixAmp.

I just received (after my first post) a balanced 2.5mm custom cable from Custom Cans and with that Q5 amplifies my HD 660 S enough even from 3.5mm line-in. I'm just a little bit surprised that my old E7 works so much better when using 3.5mm headphone-out source and unbalanced cable.

Ps. That new cable is just amazing

Wow, that cable looks... cosy
How does the HD 660 S sound with the Q5 with USB-in?

The wide angle lense of the phone makes the cable look even thicker than it is.

I really like the sound when using HD 660 S and Q5 with USB-in or even with bluetooth (Galaxy S8+).

I just became aware of this puppy!. So I can actually send the digital data to the q5 via Bluetooth from my android phone? (Axon 7 mini) . Can 24/192 be transmitted?
Any help appreciated!

Never mind. My phone does not have aptX hd.

Q5 doesn't have AptX HD... Just AptX. Bummer.

Hi @FiiO,

I was streaming Apple music (AAC) via the optical input from my Mac Pro Retina 2015 (15', highest configuration/cpu at that time). When I set at the 96kHz, it is crackling every 30-40 second. When I set at the 88.2kHz, it doesn't crackle.

The usb input works fine. The same source connected into the usb input does not crackle.

Should I request RMA for this issue?

Thanks,

There is quite a lot of marketing BS surrounding that - although that isn't really belonging in this thread...

What I will say is that I would rather have a strongly implemented AptX than a poorly to moderately implemented AptX HD….

The Q5 sounds really really good, even with just the standard 16/44 version of AptX.

That is odd since AAC base sampling rate is 48 kHz. However, I've never tried oversampling a lossy file either. Try a a lossless 96/24 file. Sony has a free sample:

If you are still hearing distortion, try a different optical cable.

Lol. My dang phone doesn't even have aptX apparently. Just standard Bluetooth. I don't think it will transmit 16/44 even. So I am back to just using it's akm hi Fi chip and headphone out to a fiio a5 amp. I like to keep the USB open on it to hook up a power bank because hi res files drain its battery fast.
If I could use a y cable and use the q5 in USB mode and a powerbank at the same time I would go for it!!
Plus my phone is USB c so there is that possible issue of the q5 just sucking life out of the phone lol

I don’t think the optical cable itself is a problem, it works well in other circumstances and bought from a reputable dealer from amazon. But I will try a sony file later.

After 2 months, always really really happy with that!

Dear friend,

Our engineer told us that because of the different material of the optical cable, the optical signal may have the loss. Do you have an optical cable with better quality for try? Sorry for bringing inconvenience to you.

Best regards

I send 24/192 files to the Q5 via optical (noname cable) without any issue.
No issues with the above mentioned samples either.

Hi @FiiO

I purchased this cable just a week ago to hook it up with my Q5 from here.
https://www.amazon.com/gp/product/B00T8HWV62/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

It is very well reviewed and a best selling cable from Amazon. At this point, I don't think that there is any defect on this cable. MAC toslink cable allows up to 24/192 FYI. Also, I am unsure whether I need to buy another for a purely testing purpose. If you know a good one (toslink cable for MAC), can you recommend one?

I am afraid I have to send it for RMA.

Thanks,
