Doesn't look like this will be a measurement king if those -93 dB results are to be believed on those numbers.
Got my Qudelix 5K in and subjectively, it sounds fine. Mostly got it to use aptX Adaptive from my phone, the app needs some of the promised features like PEQ and better documentation as to what the buttons do, but, I mean, it's fine. Get a BTR3K for wireless (I like how it can switch between devices) and a Tempotec Sonata HD for wired usage and it'll be better than an all-in one device, I think.
Hi, seeing as it looks like you're the only one on here who's got it, could you do me a favor? Could you download and play the below 30-second BS EN 50332-1 'Program Simulation Noise' through the Qudelix 5K (USB-C wired connection to source) at maximum volume with EQ off and record its output (e.g. using the free Audacity program) by connecting the line-out of the 5K via a 3.5mm cable to the highest quality ADC device you have (a PC soundcard line-in would do).
Then just upload the recorded wav file here or to a file sharing site. This would be much appreciated.
I'll see what I can do, don't know if I'll have a good enough ADC for you.
So far there are only five products that meet the criteria in the OP.
- Fiio BTR5
- Fiio BTR3K
- Shanling UP4
- Shanling UP2
- Hiby W3
- Qudelix 5K
Did you get round to making that recording of the Qudelix 5K's output in the end?
Hey, I think I just responded to you on Reddit - here's what I got, I only have a Behringer UCA202 as an ADC, and even at 1 Vrms, I was getting clipping (and -48 dB self noise no matter what?) - https://drive.google.com/file/d/1RBn_MDq-Xjd9vwYlgRPvzBK4HtZ-rlF0/view?usp=sharing (edit: I'd actually probably ignore that since I left PEQ on too)
update i realize that crossfeed in itself is not enough to convincingly mimic the sound from speakers it also needs some room echo simulation, the best i have heard in the free android apps is wavesnx, if someone has another free software (windows or android ) or sub $150 BT receiver/dac that mimic speaker sound on headphone please share.The Qudelix app shows a crossfeed option, but I don't own one yet so I can't comment on the effectiveness.
