Hidizs S9 PRO Measurements (DAC Dongle)

[IVX]

JanesJr1, if you asking about 9038SG3 "stuttering" issue pls try to check our discord channel, there are many posts about that. Usually, Androids have no that(if this is not USB-C dust-related issue), only Windows and often with the Comtrue drivers only. Sometimes need to switch Off Windows USB suspend option rct.

 

[RichT]

another great/informative review. Thanks for your good work VintageFlanker, regards

The discord site is requesting my email plus its password to verify it. Doesn't make sense to ask for or supply a confidential password!

Meanwhile I'm using the 9038sG3 on windows 11, using the generic Microsoft endpoint driver that the E!DA setup file installed for a driver. I've tried to switch modes; it seems like very low gain now, but when I unplug/plug I get either a single indicator light flash followed by nothing, or I get a slowly flashing light. From the G2 discussion on the web, what I need is the continuous light, which I cannot ever seem to produce.

After dealing with trolls and such who would just come back with a new throwaway account after I banned them, I decided that to join the discord server, you would have to have a Discord account with a verified email.
I'm sorry for the inconveniences that may cause, though I don't know what you mean by "Doesn't make sense to ask for or supply a confidential password!"

You just have to create an account like everywhere else.

Why would I supply the password on my microsoft account? Or is it asking me to create one ?(it doesn't say that).

A "discord server" is some kind of generic thing?

Discord is a text, voice, and video chat service.
It's based on servers, kind of like telegram channels.
https://discord.com/

Here you can create an account: https://discord.com/register

I don't know what Microsoft stuff you're talking about.

I had no idea what the link led to, and it asked for my email address and password. My email is for a microsoft account. It seemed like a particularly obvious phishing expedition because I didn't know what it was or who sponsored it. Nevermind, I set up an account. Thanks.

your data is simply wrong, who did measure Meizu HiFi DAC correctly may confirm DR 130db(A) and THD+N [email protected] (no-load).

It's not my data, it's from @amirm measurements here. It is, however, wrong as that is the Meizu HiFi DAC Pro but you referenced the Meizu HiFi DAC measured here which performs significantly worse: THD+N: -98dB, DNR: 96dB.

I've provided my sources, care to give yours?

Note that DR measurements were limited by my ADC. I'll revisit them once I have a better measurement setup.

Must've been a mix up discord (the official site?) is definitely legit.

Meizu Hifi USB-C Headphone Adapter Review

The 1kHz spectrum in #1 is very bad, very poor, because all that spuriae have to be integrated to get some meaningful view. It will be audible, for sure, as a sound signature. Another toy rather than audio component.

I hope you can get a Cosmos ADC + APU too!

 

[staticV3]

Yup, just waiting for XLR and 3.5mm plugs to be delivered so that I can make appropriate cables

You and I are in the same boat mate !

If I may, and I think I speak for quite a few people... E1DA/ @IVX : Entire wiring for Cosmos drives people mad. Please sell your own cables !!

Thanks guys. Do I interpret correctly then that the device can meet its specification under certain operating conditions, but is highly sensitive to power supply noise and possibly loading?

 

[VintageFlanker]

Can you do a plot to show if it has the infamous ESS IMD 'hump' ?

I could or... cannot. Multitone can run SMPTE IMD Vs Level.

Hidizs S9 PRO:

You see quite a typical ESS Hump... Problem is that we don't know if it comes from either the DAC or the Cosmos ADC (or software itself, for that matter).

As an example, here is the Matrix Mini-i Pro 3, presumably not subjected to Hump...

Yet, it still occurs... BTW, @IVX, @staticV3, did you try to replicate this in Multitone?

We talked about it there:

No, it was my lack of familiarity with the site and over-reacting to the request to validate my email by providing what I thought was to be the existing email password rather than a password for a new account. I just habitually over-react to security situations because in my work I have confidential, regulated information on many individuals and am audited on my security practices.

I own this unit. Great little performer on the go. I pair them with 7Hz Timeless IEM and have no complaints. I wish the balanced connection were a female 4.4 instead of a 3.5 but I understand the size constraints of the unit. I’d accept a slightly larger form to get a 4.4 female.

Very good points.

Matrix data suggests hump comes from the Cosmos ESS ADC @IVX ?

@pkane and @mansr also see this hump with your Cosmos ADC? Measure a good low IMD non-ESS DAC?

 

[staticV3]

I'm looking into it right now.
One question: the unit that AP call "SMPTE ratio (dB)", is it synonymous to "IMD" in Multitone and "IMD DIN" in REW, or is it synonymous to TD+N?

If it's the former, then how come my $100 SG3 beats the D90SE by 20dB at -60dBFS Generator level?
