Measurements and conclusion

Measurements WiiM Pro Plus
We also measured the WiiM Pro Plus, of course. We have to say: for a little 249 euro device, it’s just impressively good. Few harmonics, fairly low noise floor ánd a fine dynamic range: 113 dB / about 18.8 bits. That’s better than many streamers around 1000 Euro.
Jitter is not so good. We see a lot of grass and noise. Also the high-frequency noise in the noise / interference measurement could of course be better. But this is all due to the phone adapter that powers this streamer. With a decent power supply this goes down a lot, we estimate.

Meten is weten ?
Al vorige week heb ik de metingen bekeken van Audio Science Review.
Een site met goede metingen, maar ‘andere’ oren.
Bij ASR ging de freq. response na 20 kHz al steil omlaag.
Jouw meting laat een ander gedrag zien: recht tot ca. 80 kHz.
Ik vertrouw het meest op jouw meting, omdat dat het meest past bij een apparaat wat in staat is om signalen te verwerken tot 24b 128kHz.
Het gebied, net boven 20 kHz, laat de tekortkomingen van de apparatuur goed zien.

I am really interested in knowing how far you can take this streamer/dac combo with a Dodo power supply, for example?
Is that power supply overkill or will this then become a killer streamer for £1000?
Maybe a test with an external DAC?
Modern chipset ESS 9039*, AKM 4499* and R2R.
“Frankly, the WiiM Pro plays well above expectations. The AKM 4493SEQ dac chip” and €249
-> WiiM Pro PLUS
