Another question I haven't seen here. Is the analog RCA in the do5 the same used in do3? I´ve researched a lot and bot units will serve me right but I will prefer the do3. I will connect TV on digital, turntable with the ifi zen phono pre on RCA, computer and phone on usb and BT. How "bad" would be the RCA in this set up? Thanks and sorry about my english, not my primary language.

Hi, my name is Alfonso, I have been around here for a while but only as a reader. Now I need help from aiyima D03 owners to try to solve my problem. I apologize for my English in advance.

I get small random sound cuts through the optical or USB input. It is not a TV or PC problem because with a marantz amplifier I don't have this problem. In the attached videos you can see the problem, sometimes it happens in a few minutes and sometimes after 30 minutes.

I will list all the tests I have done to help find a solution:

-Connected by optical cable to a TV and using native TV applications I have the problem, I tried two different cables

-Connected to a PC via USB I have the problem.

-Bought another Aiyima D03 unit on amazon to see if my unit was defective, with the new unit I have the same problem.

-Same tests with another brand amplifier I do not have this problem (Denon and Marantz).

-I have changed the audio connectors and cables that connect to the speakers.

-The unit does not feel hot and I use air conditioning in testing to avoid overheating.

Thanks in advance

I use windows 11 and spotify or Tidal.
mine tried it in usb with windows 10 and foobar2000 latest version in exclusive mode and did not lack with any audio file with different frequencies from 16bit up to 24bit and from 44100hz up to 192000hz. If the audio signal does not reach aiyima d03 well, this defect happens, maybe it happens to you, I don't know.
sorry my english, but i use the translator, i'm italian

I would imagine this would be an interesting product to test - please @amirm :) as I haven't seen many tests on FDA anywhere.

Specifically I like the idea that its pure digital inputs into the TAS5624A (which may give similar quality output to A07) - if they have engineered it well it could a winning product.
