There is now a new firmware update V0.49 (April 1, 2025).

(comparison to Centaurus) Passion for Sound has already announced an upcoming review on his YT channel. https://www.headfonia.com/topping-d90-iii-discrete-review/ Also some user reviews on: https://www.head-fi.org/threads/topping-d90se-updates-to-d90-iii-discrete.974127/ Also some buyers'...

I had the AUDIOPHONICS MPA-S250NC and AUDIOPHONICS AP300-S250NC. No Problems at all. I would buy there again.

More generally, is there really a risk of damaging the power supply if the supplied device tries to draw more power from the power supply than possible? Or would the only consequence be that the supplied device would not work?

I asked myself a similar question: I have a WiiM Pro requiring 1.5A @ 5V according to the manual. I just tried to run it with the P50 and it works flawlessly. I use only one of the 5V outputs at the moment but it also worked in the past using the second 5V output supplying a miniDSP DDRC-22D...

A real mystery to me is that the topic of digital room correction (DRC) still receives so little attention among audiophiles. For example, it was almost non-existent at the High End 2024 in Munich. But you could get information about what felt like thousands of cables. (But I have the impression...

I'm very interested in that. I have a Loxjie D30 DAC that I use as a preamp for my AUDIOPHONICS AP300-S250NC power amplifier. On speakers with normal efficiency I have to set the volume control to around -50dB. I wonder if I'm creating distortions by doing this?

I consider to use the D40 as Preamp with the AUDIOPHONICS AP300-S250NC. "This amplifier does not have a decoupling capacitor, so it lets the DC component of the signal through. Make sure your source has no DC component present at the output." Does anybody know whether the D40 provides such DC...

I have a transistor amplifier and a tube amplifier (Oldchen EL34-B), both of which I want to use on my speakers (not at the same time, of course). To switch between these two amps I have an amp switcher (Dynavox AMP-S MKII). When I switch the amplifier switch from tube amp to transistor amp...

Great review again. I appreciate these as really objective in the best sense of the word and you don't, for example, bash a manufacturer per se.

Die digital version of the flex has optical and electrical SPDIF outputs but no i2s. I do not see a simple, or any, way to output i2s. I do not think that e.g. something like Dirac DRC is anything messing. (quote: "No need to mess with the insides of the flex) I do not think that the DAC of the...

I can confirm some statements made before: I started with the RPi4 + Volumio (and also other streaming software like Moode). I used it for about an year. It worked but it was not very stable. So I sold my RPi4 and bought the Blusound Node N130. It it much more stable now. I am quite happy now...

But you can also buy the Flex w/o Dirac (might be better due to tax reasons if you import it) and upgrade it afterwards. No problem.

Should be so. I had cables made to these specifications to connect my subwoofer. A subwoofer is an unbalanced power amp including speakers, if you will.

Just so I understand you correctly: By that you mean that the directivity in the vertical dimension has a high symmetry, i.e. that no lobe tilting can be determined?
