The point is having a ADC is useful to monitor how your elements are behaving. Adding the function to differentiate is an option that WiiM initiated, purposefully in their context as you explained.

I understand. So we have to simply focus on the management of the source with the ratio between digital level and voltage output in the case of a DAC. From my perspective a precision ADC helps to discover at which best operational level a device can be run. It makes it useful to a broad range of...

Is -6dbFS a good test signal level for mainstream benchmarking ? Or reaching the closer to clipping level is the best practice ? If a device plays better numbers at -12dBFS is it valid ? Can you read the absolute voltage output level of a device with the Cosmos capture from the get go ?

Common cassette tape decks provided between 30K to 100K ohms of input impedance, some reel to reel had 50K ohms. Integrated amplifiers had 25-50 K ohms impedance for line inputs when they were popular. The higher setting of Cosmos is 13,6K ohms and it starts at 640 ohms.

Looks like a 2 sliders situation, you should figure it out in 2 minutes ! The reward is not in the journey, but in the tweeking it seems.

When plugged on a Linux system, the E1DA Cosmos ADC shows 2 sliders in ALSAMIXER. There is "Line" and "Line 1". Windows does not shows 2 sliders. I have never met a documentation explaining what the second slider does. This device needs a manual. And even better than that, I think it would...

Some of the iconic early Philips models were exactly like that. the CD 100 is still very desirable ! It makes sense besides a turntable on a low and wide Kallax. I feel you.

Top loading does not integrate with ease a stacked system or inside a furniture. For the few people that still hangs on to the medium a real gift would look like the Hitachi 1000. The Hitachi 1000 - front loaded vertical cd player had most of the meaningful features checked. When it was playing...

How to measure a phono preamp at home without a turntable with a test record ? Do classic audio files RIAA treated from a software like Audacity or SOX are good enough ? How to feed the tested preamp a signal with the required impedance and voltage ?

The PFFB treatment brings -10dB better specs here and -6dB better specs there. It is a true validation of the effort and continuing improvement of this TI chip platform at this price range. V3 Mono is clearly a gift for XLR users, and a promise of greater things to come for the platform. It...

I wish ASR could featured more french manufacturers besides Focal. Cabasse, Elipson, Triangle Hifi, Davis Acoustics, all produce lovely small speakers. I don't know how well they are distributed outside Europe.

Can such a circuit be replicate on a bread board ?

Just one metric can not be enough to evaluate the adequacy of an amplifier to a particular setup. The specification of your source(s) and your speakers require to account for power requirement, impedance tolerance, probably gain also. Not to forget convience on a daily basis. Having an amplifier...

So if clipping the amplifier is the issue, and the intensity of the signal is the culprit, can we say that a louder cartridge will always be more prone to it in a fixed setup ?

A 40€ quality preamp can be as enjoyable as a reference 350€ preamp, and almost identical while ABXing. You can test an external preamp configuration even while upgrading the stylus. You don't need to break the bank to further your reflexion. I never heard of the pops and clicks situation from...
