I saw some earlier posts that suggested that the Amazon offering was subject to a very long delivery time from China. If that had changed, then I'd probably buy through Amazon.That's the regular price on Amazon for the last year or so.

I'm not an expert on their products, but from the image, the product is theStrangely, Japanese Amazon doubled the price a while back, BUT, they have a newer model selling very cheaply.

For power and features, compare the E1DA 9038d and this Tempotec BHD Pro to the newish Fiio KA-15. Fiio analyzer printout shows balanced 4.4 mm 560mw/ch into 32Ohms, 10 band PEQ (PC or phone interface), 109 dB sinad, dual CS43198 DAcs, and if used with a phone, option to connect incoming calls. That one might be interesting to check... prices vary ~$90-$110. See https://www.fiio.com/KA15_parameters . It's set up to toggle between high current draw / desktop mode and lower-draw phone mode.Thanks @amirm This is a fabulous device! With the price, spec and volume controls, I'd buy right now if I didn't already have my E1DA 9038D that I bought back when you reviewed it. It might not be long before that 'King' of small form factor dongles is matched or beaten.
Downloaded and installed firmware for Tempotec Sonata BHD from their official website. Now the device has stopped working correctly. The indicator does not light, the sound on the device is not adjusted. Now the sound is adjusted only on the source - on a laptop or on a smartphone. Maybe someone can help find the correct file for the firmware?

yes i used this file exactly and now i have a problem.View attachment 425339
Based on your picture.
That's the only one available so try reading the how to instructions and do it again. Obviously something went wrong.yes i used this file exactly and now i have a problem.

Then write a mail to them and ask for an older firmware to send you. It won't be quick nor very plesent but I believe they will do that much. If that doesn't work they will ask you to send it back to them in China on your own expense so that they can disassemble (read the EPROM on programator) and check it out and they will send you another one but that will take a lot of time.I tried to follow this instruction. using my data:
VID_22E1&PID_E205

The process completes successfully and the "OK" window appears
But the DAC lights up with a red indicator. And after reconnecting it - it works as I described above - incorrectly.

Since it's advertised together Sonata E35 and E44 I think that firmware is for the older Sonata BHD (2.5 mm) and never tried to flash it on my BHD (the same as yours), since i have no issues with it.I tried to follow this instruction. using my data:

earlier, before the unsuccessful firmware update, this DAC was listed in the system under the name Sonata HD. This was somewhat strange, because the name is BHD.Since it's advertised together Sonata E35 and E44 I think that firmware is for the older Sonata BHD (2.5 mm) and never tried to flash it on my BHD (the same as yours), since i have no issues with it.
Maybe it was to address some THD problems that those models shown in L7audiolab tests under load:

https://www.l7audiolab.com/f/tempotec-sonata-e44/
Tempotec made a bit of a mess with these device naming and I can clearly see this type of problem could arise, so hopefully they have to send you the original firmware for the new model, good luck.
Yes, it's seen as Sonata HD (confirmed both on linux and windows), so nothing strange on your one.earlier, before the unsuccessful firmware update, this DAC was listed in the system under the name Sonata HD. This was somewhat strange, because the name is BHD.
I am happy to report that Tempotec support responded quickly to my email and they sent me a working file. The device is now working again.Then write a mail to them and ask for an older firmware to send you. It won't be quick nor very plesent but I believe they will do that much.

indeed, they sent a file for reflashing, which I could not find in open access on the network. everything worked immediately. Product ID is now E208.Since it's advertised together Sonata E35 and E44 I think that firmware is for the older Sonata BHD (2.5 mm) and never tried to flash it on my BHD (the same as yours), since i have no issues with it.

I hope in the future you won't flash new shiny things just out of curiosity.I am happy to report that Tempotec support responded quickly to my email and they sent me a working file. The device is now working again.
actually it's normal. the experiment with the firmware became a useful experience, and if someone has a similar problem, he will find our messages and this will help him better understand it. you can apply directly for the file. the trial and error method is the only working one
