Too bad we cant meet, otherwise i would bet you you wouldnt be able to tell which is which if you didnt know beforehand :). Unless the BTR7 intentionally colors the sound like the ifi blu does.

Power output difference imo isnt worth mentioning as a pro for the BTR7, as in reality 320mw its a 1db loudness difference over 240mw. Also max voltage output is 3.2v on the balanced port fpr the BTR7, while its 4v on the 5K, meaning 5K will be louder with higher impedance headphones. Edit...

The stream gets encoded(compressed) at the transmitter side, sent to the receiver at lower rate than 1411(ive seen FLACs at around 700-800kbps), and decoded(decompressed) at the receiver side. 1411kbps is the rate for uncompressed 44/16 audio. It can be compressed and still be lossless, lossless...

Download older version of the app from here - https://apkpure.com/qudelix/com.qudelix.qudelix/download/2.3.2 Install manually and dont update it through playstore.

Power is voltage multiplied by current. For low impedance you need an amp that can provide higher voltage(its what affects the power output, current is decided/limited by the impedance).

Yup fair assessment, if i remember correctly they didnt make any use of the updated chip in W3 Sabre compared to the original W3. Maybe they implemented something by mistake in this new one :). Like upgrade the EQ finally and LC3 support, which would be possible with the new chip. One can always...

Just noticed Hiby has released W3 II. QCC 5125 with bt 5.2 and CS43131 DAC. Has anyone had a chance to play around with it? @ClieOS any plans on doing a review on that unit?

I assume they forgot to remove the limit in the mobile apps. Left them a message, so theyll probably fix it.

Q7 was the limit for v2 firmware, but in my short playing around with v3 through the chrome extension i see that Q can go up to 15 now. Edit: Just tried through the android app, and it wont allow value higher than 7, so probably a bug, idk. Edit2: If you set Q value of 15 in the chrome...

Doesnt matter if its iems or full sized headphones, what matters is the sensitivity. You can have iem and HP with same sensitivity and have same battery life. So you need to compare 2 specific models(iems and HPs). Edit: For some reason i read your comment as if youre asking compared to IEMs...

You wont be ever dangerously draining it. Dangerously draining it would be going below 2.5v, safe is considered 3v, 3.3v and above is for longevity. Qudelix 5K has cutoff voltage at 3.5v under load, meaning it would recover few milivolts when the load has stopped, meaning it will be above 3.5v...

Proper Li-Ion charging involves 2 stages, CC(constant current) and CV(constant voltage). When it reaches the 100% full voltage(in 5K case 4.35v.) charging circuit continues charging and monitors the voltage not to overshoot 4.35v and it gradually decreases current till it gets to about 10% of...

For Windows use Equalizer APO + Peace GUI

Disabling charging does just that, disables charging. The 5K in this setup still draws power from the device to power itself(doesnt use its battery at all), without pulling the additional 200mA that charging uses.

In reality 340mw over 240mw is an increase of 1.25db in loudness, which is pretty negligible. Also nothing wrong with the build of the Qudelix, just using cheaper material, full plastic body, which on the other hand helps with the reception of the device as there is no metal to reflect the signal.

God damn, and i thought the previous drop price of $89 was a steal. Now on sale for $79, the right time to get that spare :). https://drop.com/buy/qudelix-5k-bluetooth-usb-dac-amp

Set headroom to -6 or -12, depending on what negative pr-egain most of your presets have, and remove the pregain from the presets. Ofcourse this way you can use presets with pre-gain up to -12, ones requiring more would introduce some or lot of clipping depending on how big is the difference.

Mind you that every doubling of power adds 3db of loudness, so its not as big of a difference as it might seem at first.

Always nice to have a spare. Though one inconvenience that might be a dealbreaker for some, is if you have 2 of them paired to the same phone you wont be able to use the app with the second one unless you unpair the first one..

Havent heard the blu, but by your description that type of sound youre looking for is achieved by upping the mid-bass so it bleeds into mids(undesirable for some people). With GEQ you would be playing around with 125Hz and 250Hz sliders

Bluetooth works at 2.4GHz and AC Wifi at 5GHz. The higher the frequency the more trouble the signal has going through obstacles.

It is: R- R+ L+ L-
