This is NOT a review, but an overview of the Aoshida A6 amplifier
DISCLAIMER
I know that many on ASR completely denigrate tube products, especially the very cheap ones with more aesthetic than functional purposes, as in this case, but considering the probable intended use of an amplifier in this price range and the other characteristics, I thought was an interesting product to try.
I still don't quite understand what the relationship is between aoshida, douk audio, xduoo.... Many of these products seem to come from the same working group.
This amplifier is currently on sale on amazon italy for 99 euros. It seemed very interesting to me given some characteristics:
- Bluetooth LDAC
- MA12070 amplifier chip (single)
- Headphone output
- Dedicated RCA and Bluetooth input selector
- aux output usable to drive another amplifier or a sub
- Buy for a song
It has just arrived and I can already make some considerations.
It is built very very well, solid, knobs of both volume and tone controls that go in steps and with good feedback, wider than the fosi audio tb10D that you can see next to it in a photo. The front thumbsticks feel solid. The backlighting of the tubes can be set to orange, green or off, I like orange light. Behind there are the outputs for the passive speakers, the RCA stereo input, the bluetooth antenna and the aux output with 3.5mm mini jack.
I first tried bluetooth to see if it was indeed ldac as advertised, and indeed my huawei connected in ldac. This feature for me is already worth the 99 euros! Although the analog to digital conversion is done by the bluetooth chip, this will always be a much less problematic bottleneck than the difference between for example ldac and SBC or aptx. I have also tried the RCA input with my external DAC and it works as you would expect. Same thing for the aux output from which the full range signal comes out, so it will then be the task of a possible sub to carry out the lowpass cut.
The supplied power supply is a 24V 4A (not 24V 2.5A as erroneously written on amazon), and I imagine that the power is about the one you get with smsl AO100 or sabaj A1 (new version), therefore not high, presumably around 20in clean watts into 8 ohms.
The tone controls seem to work well, they should attenuate or boost the relevant bands by +-6db, there is no louder signal or step to pinpoint the flat point, but by ear it seems to be right in the middle or very close .
I noticed that using bluetooth, when I stop playback from my phone, after about 3/4 seconds I hear a "clack" as if a relay was interrupting the circuit, the same noise is heard immediately when playback resumes. From the little I've heard so far it seems to play normally, with nothing broken, by ear I don't think I would be able to distinguish it from the fosi audio bt10D.
At the moment I have nothing more to say, listening tests will follow in the next few days and I will update the post if there are other interesting things to say.
For the moment, the feeling is that with a good amplification chip, a good Bluetooth, finally ldac in a product under 100 euros, a good construction and a flashy but nice aesthetic, and its aux output, it is a product that is fully worth the little money required
