Hello! Recently, I bought a pair of PSB Alpha AM3 speakers. However, when I use my computer as the audio source and connect the computer's USB port to the speakers' micro USB port, I found that the maximum resolution is only 16bit/48kHz, which is inconsistent with the 24bit/48kHz claimed by PSB. I tried different computer and cable, doesn't work. I also contact PSB, no response yet. I'm curious what the problem might be?
 
You have native 24/48 content?

Yes ,I,ve some 24/96 contents. When playing them by Foobar2000, if set output depth as 24, the system will report an error. Besides, there is no 24-bit option in the Format tab for the speakers either.
In fact, I found this guy has the same problem with me https://darko.audio/2021/02/psbs-alpha-am5-powered-loudspeakers-are-a-600-solution/ . As he said "Let’s begin with a technical issue. Using a Raspberry Pi 4 running Ropieee as a USB streamer, Roon automatically converted 24-bit data to 16-bit data before sending it on to the AM5 even though the AM5’s specifications state that the USB input can handle 24-bit/48kHz data.

 While PSB claims a 24-bit/192kHz limit for Toslink, I was only able to play 16-bit data without issue. When attempting to playback hi-res, 24-bit music via Toslink, the AM5 went silent and the status LED on the left AM5 would go into error mode, blinking red. Limiting data to 16-bit from the Toslink streamers to the AM5 using Roon’s Device Setup options solved the problem.

 As such, I was only able to review the AM5 streaming 16-bit data. Despite repeated requests for comment on this issue, my contact at PSB remained schtum."

24/96 is isn't 24/48. I'd assume it would have to be 24/48 for the speaker to handle without altering. I wouldn't worry about it in any case, 16/44.1 is perfectly adequate. More curious than anything.

I agree with you. 16/44.1 is more than enough for me. I'm just curious what happened, you know that "Curiosity killed the cat".:p
 
Found the 24 bit claim in reviews but not on PSB website... Did they change it after discovering the error?

Yes, it's the problem. I didn't find any official statement by PSB. All is review said "24 bit ... clamied by PSB".o_O Possibly it was originally 16, not 24.
