The Qudelix-5K thread

[Safeinthemountains]

Had to return my unit today. Not useable on the latest firmware for calls. Dropping out during calls is not acceptable. No issue with any TWS or ES100. Total shame.

Hi, why don't you wait for the next FW update if it was working before ? You returned it after discussing with Qdelix support ?
I have had it for a few weeks now, so no FW upgrade yet; is it imposed by the app ? Is there a way to downgrade to an older version ?

You can downgrade FW using Chrome browser version of Qudelix application.

Thanks michusxx, good to know, this is a nice feature !

So, I need another Q5K. Qudelix site shows they are out of stock. Amazon has stock but don’t have QX-Overs listed.

Are they worth buying separately or wait for Qudelix to restock the 5K?
They seem uniquely created for the dongle and probably a good bass cannon.

Thx

Just received my first Qudelix 5K, what an amazing little device! kicking myself for not buying this sooner, anyone that wants to grab one in the UK from a trusted source I got my mine from here,

https://eliseaudio.com/products/qudelix-5k?_pos=1&_sid=37ce53309&_ss=r

Couple of questions,

1)I'm only using IEM's with this device, currently Moondrop Aria's, is there really any benefits from using the balanced output?

2)In the volume section of the app, what do you guys recommend setting the right volume to, I'm assuming this sets the voltage/gain? At the moment I have it set to 0.0dB/1v?

3)Battery saving, being that I'm currently using single ended connection and Spotify as a source do I really need LDAC running @ 96KHz?, can I trim some settings to provide better battery life?

Ad1.
I'm also using Q5K with Aria IEMs. Since it is necessary to limit 5K output to 1V because of Aria sensitivity I don't see any benefit from balanced output (as the main reason for that functionality is to increase power/voltage). Balanced output shall not offer any better quality in this setup.
Ad.2
Limit the main volume in app to get comfortable loudness during listening (the volume in source - i. e. smartphone - should be maximum). In my case with Aria it is about -10..-12dB depending on source application. If you apply any EQ (with necessary negative gain compensation) then those values will probably be more like -10..-9dB...
Ad.3
Definitely it is recomended to reduce rate of LDAC to 44/48kHz. The badwidth of BT connection is limited to 990kbps so it is enough rather for 44/48 kHz data stream. Using 96kHz will need two times more data rate, so it will end up with more compression to fit it into 990kbps...

Thanks,

Just some clarification regarding the 'recommended' volume settings as I've found this bit a little confusing, your saying max out the volume on the left (the phone) and then control the volume using the Qudelix rather rather than maxing out the RMS volume on the right to 1v and controlling the volume with the phone?

edit -

Output power I've set to normal?

Yes. You should control volume on Q5k side since it is done in analog domain so it not affect the quality (
SNR in particular). If you control volume on phone then it is done in digital domain because further transmission to Q5k is digital. Reducing signal level in digital behave like reducing number of bits - so instead of 16-bits recordings you will have for example 13..14 bit equivalent depending how much you reduce level...
That's theory. Of course the question is how much that difference is in reality audible... and it may be more convenient to use phone control (especially when walkin outside)... But if you looking for high quality then just set volume in Q5k...

And setting power to normal means setting output to 1V...

Thanks you've been a great help.

Nice to be able to help.
BTW. How do you like Aria IEM? Do you use any equalization for it?

Love them, sold my Blessing 2 as I found them too fatiguing, technically B2 was amazing but really not a fan of the tuning, the Aria's are much more my cup of tea, no EQ for me.

Same for me back then, until now i still keep my Aria and never look at B2 anymore (got the Variations though), but actually you can eq B2 reducing the mids-high while bumping the lows to make it less fatiguing and more fun, but yeah having many iems pretty much a hassle to turn off and on the eq

Anyone else with these combinations? Qudelix 5k with 7Hz Timeless and QX-Over. Curious to hear your thoughts.

The 5k is pretty nifty and small. Love the AutoDSP, and the other various little settings (batt, auto off, etc.) I run it off my Galaxy S10 with LDAC settings. Extremely happy with this very portable setup. My only complaint, a dedicated on-off button would be helpful. Been using the app to make sure that it shuts down to save battery.

To me, the 5k with Timeless combination (with Comply T400 foam tips) has pretty good detail and is fairly neutral with the foam tips alleviating the slightly elevated mid-bass. Been using the Auto DSP. Havent really tried manual EQing. Chose the foam tips cos the silicon ones hurt the inner ear after awhile.

The default EQ for the QX-Over makes it sound a quite airy but light out of the box. No complaints considering the price point though. Haven't really tried fiddling with the other settings yet though.

Has anyone found a decent case for the 5k? The Dignis one is a little pricey and constantly sold out...

The SO used the Timeoess with the Q5K until it got lost. She rated it but found the S12 easier to manipulate the bass the way she likes.

Is the QX-over worth it? Qudelix is out of 5Ks and I found Amazon has stock but no QX-overs. Is it worth ordering just the IEMs separately or waiting for 5Ks to restock with Qudelix?
