Just another Hanpin DD? Looks similar to Magnat 990 etc. As for specs they are not that bad

Archimago input on the Icon's filter (MQA QRONO d2a) https://archimago.blogspot.com/2025/01/lenbrooks-mqa-next-generation-qrono.html

I believe E70v is about 119 dB. I just checked my Topping to be sure that I can get the better results with my ADC. I tried with 45 Hz limit (one I actually use). It's mostly the same as with the full range Dirac. Complete disaster is there, SNR 82 dB. I'm afraid the below pic. is not very...

I tried to re-measure Icon using REW beta with cross correlation feature. Can't increase the gain as my ADC overloads on higher input. XLR, 96k, fixed volume, tone control and Dirac are off.

XLR Scarlett 2i2 3th gen, THD via Amir is below. I agree with you that my ADC can be worse than the Icon. But I believe at least Icon's SINAD is not lower than I got. Scarlett 2i2 3th Yes, I use Dirac. It was the main reason to buy the new Bluesound. My measurements above are with Dirac off.

108 dB via the official data-sheet. My measurement for Icon is below. It's done with Focusrite ADC, so not precise. Anyway is rather close to the specs.

Can it be my TRS1007 one track issue? VM540ML and 95E also have some small waves in the blue graph. And I measured them new.

Maybe, I got it used. PS: I have really jerky one :eek: I even didn't post it in the thread. Comparing to this re-tipped OC9ML my AT33SA is fine, at least for me.

Oh, yeh. Mine has the golden screws from the box.

Audio-Technica AT33SA 2.0 g 100 Ohm I got it used but from a trusted seller. Declared approx. 100 hours in use. Magnat MTT 990 -> Musical Fidelity MX-VYNL -> Scarlett 2i2 3 gen Clearaudio CA-TRS-1007 8 Hz lateral resonance by HFN test record with Magnat tonearm Comparing to my VM540ML...

There is nothing tricky. 1. Play and record both tracks on your test LP continuously. Then save it as one file. So your WAV file has to contain 2 tracks: L and R. Example for CA-TRS-1007. It starts with 1 kHz tone then sweep for L, silence, 1 kHz, sweep for R, silence. 2. Update parameters...

Please consider my post only as a question. Just surprised that my 540ML and 95E measured better. I'm going to check some settings and provide the final version posted by the thread rules.

Does anyone have AT33SA? Just to compare but can't find in the thread. I got a quite disappointing results. Looks like brighter AT95E :facepalm:

Yes, red one is via Audioquest filter that reduces 50 Hz AC noise and it's harmonics. I use Scarlett 2i2 3gen, so it's just for fun as both Icon and Wiim have better SINAD. Anyway here are MTs. Blue - RCA Wiim Pro Plus, Red - RCA Icon. Mostly the same. I guess because of the ADC limitations...

Trying to measure my Icon and found that it depends on AC, no matter XLR or RCA out. Red - with AC Filter (Powerquest 2), green - direct. Checked the same with Wiim Pro Plus, and there are no differences for both filter/no filter. Seems not to be audible but...

Can you also check multitone with Umik? I compared Arcam SA30 with Topping PA7 Plus (KEF R3 Meta) and got the same THD via sweeps but some deltas for multitone. Something like the pic below. THD is mostly the same for both.

OK, updated.
