Is there any audible SQ difference when passing data with bluetooth or cables ?
Back when bluetooth was new, I could barely discern a difference, but I can't any more. The codecs have probably improved.

Is there any audible SQ difference when passing data with bluetooth or cables ? I've just received portable bluetooth dac/amp and honestly if I'm matching it against my wired S1 without any EQ filters I can't tell any difference between them from any of my HP. I'm not even using their highest bluetooth LDAC codec as I'm stuck with iphone and AAC.

I’m in the market for going wireless, which dac/amp did you go for?Is there any audible SQ difference when passing data with bluetooth or cables ?

AAC is certainly good enough for audio specs. Most new generations of blue tooth are meant to improve bandwidth for further distance and larger data streams like 4K video.

Ps: My experience with AirPods Pro has been very good so in want a solution for my headphones now.
Bluetooth codecs where made purely for audio transmission and connectivity with devices that doesn't require much data to be passed, don't get mistaken by wireless video streams, these are different beasts with dedicated antennas, different hardware and protocols are used there. BT could never achieve such speeds and In no shape or form it could deliver video stream, but good thing for us it seems that for audio it doesn't need much. Only issue is pairing and how devices used for audio en-codes and decodes data passed over BT.
Under the BT naming, they now use something that's pretty much wifi. At least it's way closer to wifi than it is to the original rubbish that was BT back in the days.Bluetooth codecs where made purely for audio transmission and connectivity with devices that doesn't require much data to be passed, don't get mistaken by wireless video streams, these are different beasts with dedicated antennas, different hardware and protocols are used there.

No, bluetooth was created for data transmission, not just audio. Early applications were also for door locks. Bluetooth 4.0 has a speed of 25Mbps: high enough for 4K video. Here are video profiles currently available with Bluetooth:
Audio/Video Assigned Numbers
This is the link of what bluetooth is “capable” off.. As I said in BT connectivity numbers doesn’t have much in common with real-life experience. Better show me an app/phone that is capable to transmit video over BT. Ok if not found at least give me a codec which transmits video over BT Large speeds can be achieved with wifi, but many things needs to be considered as well, overlay with other networks, setup, distance. Large part of my job is with such IT infra networks
BT and wifi are different sings, even concept is similar BT won’t be able to achieve what wifi has to offer, but it doesn’t nees to
No, this link lists the actual current protocols. I'm not sure if you read the link, as it clearly states media type 1 is video, and MPEG-4 is an accepted codec (and h.263 is actually an older format). Probably from when it was first used for connecting digital cameras with cell phonesl. Wifi is more standard for transmitting video, but there are still uses for having point to point data transmission. I am involved with software development and do know what wifi is, thanks. I'm also involved with video production. Your claim that bluetooth won't be able to have speeds for video is easily disproven. It's even theoritically possible to transmit 4K with BT 4.0: compressed 4K for streaming is usually around 20Mbps.

Your link has nothing to do with streaming video/audio and this magical 24mbit/s is not over the bluetooth. Different purpose and different protocols are being used, you should be aware of such in software dev. Streaming audio via BT doesn't have good throughput, no protocols are available for video. Data upload/download works completely different than streaming as it can simply push data in larger chunks without worrying of any latency and simply re-try with any packets lost.
Ignore those "BT" advertised nonsense, they have nothing to do of what we hear over BT connection. Best guide below:

My link does: it shows actual application of an external camera as essentially a webcam for smartphone (what a remote interface uses). I can't believe you're accusing me of misguiding people. One doesn't need to be in IT: you clearly are not reading any source. You don't believe my source from bluetooth themselves, that list the actual protocols!! Being in software development, I do have to read what material from the creators of a standard. I would assume someone who claims to be in IT would also need to. But an example from a developer forum, that's not some future hypothetical:
2012: Android: How to transfer video and audio via bluetooth connection?
2016: Video Streaming over bluetooth
And apparently, you don't read your link:
And the real indicator...bluetooth has the A/V Distribution Transport Protocol. If it didn't have video standards, it would be called Audio Transport Protocol....not Audio/Video!!
I don’t want to go back and forth with you.
Something I agree with: can't have a constructive exchange with someone who denies facts presented to them (current BT video protocols).
correction no dedicated video protocols over BT due to its nature and limitations
