Topping D90SE Review (Balanced DAC)

[nelamvr6]

Well, I had to do it, I ordered an D90SE to replace my current DAC, a D90 MQA. I know that the D90 MQA was already about as transparent as a DAC can get, but those extra 3 db of SINAD are just too tempting to resist!

After I placed my order, I went to Topping's website and downloaded the manual. I discovered that Topping did indeed address my only real complaint with the D90 MQA by providing an auto shut off mode for the OLED display. Kudos and thanks Topping for listening!

Now comes the hard part, waiting for Apos to get my new toy to me...

That's the standard measurement of @amirm if you feed same signals like mono to both channels. But if you feed different signals (stereo) to left and right channel, the 3rd harmonic distortion is measured so high, see https://www.audiosciencereview.com/...ange-smsl-m500-high-3rd-harmonic.22710/page-4 post #70, the measurement from @WolfX-700 .

Yes, I already told you that I'm aware of that thread but as it is, the chart remains and the method measurements are fair for all DACs, just so happens that someone found this on one particular DAC (or two). To be fair, then all DACs should undergo the stereo signals like you mentioned but I don't think that's gonna happen and that is why the chart stands which is 117 Sinad for SMSL M500.

I have and the over all presentation is better. My amp has a 50k ohm inputs, maybe that has something to do with it. I also run my subs off the RCA outputs of the pre90. It works great. I don't think the d90se was really intended to be used as a pre amp. Maybe we can ask @JohnYang1997 about it.

D90se should work fine directly to the power amp. And it should give very good results given the noise floor is finally low enough to not add extra noise. Pre90 should give more SNR at lower level. But D90se works just fine and perhaps better close to max level. 4V mode gives a little bit lower output noise.

Has anyone's display started to do this? It does it on every screen, but the line is not consistent. It almost seems like there is a font error.

Mine doesn't do that.

Ask your seller for a replacement.

So you recommend using 4v into my Pre90 then?

I just have received my DAC and I am a little disappointed.

i owned till now a "half the price of D90SE" DAC and I was very satisfied. I am an audio enthusiast for more than 30 years. Till recently I didn't give much attention to digital world, since always seemed dull compared to my analogue sources.
Lately seeing the highres audio etc, started to look into it to see if I can get decent sound from digital sources. I found out that things are really getting better, so I bought a lot of hires music (i prefer to have it than streaming). I was quite happy with the outcome, even if analogue is still better but I could now listen with pleasure to digital audio. My previous DAC has as said half of the price of D90SE.
Since I try always to upgrade my audio, I decided based on the reviews here to buy the D90SE. A very disappointing experience, expected a lot more. I was balancing if I will write this post but I decided to do it, even if I am expecting flame...

So let's start.
System accompanying the DAC: Nordost SPM reference cables (tried also OCC Oyaide and Neotech), Symphonic Line RG-3 turbo preamp, 1 KW pure Class A monoblocks, Magnepan 3.6, Focal Aria 948 and Focal Grand Utopia.

Good things:
Quiet: The quietest solution ever! It is THAT quiet that you think your ears have problem.
Detail: Yes, there is detail, unquestionably. In certain areas of the frequency ranges there is more detail than my current DAC.
Bass: A LOT of control. It never looses control. Good extend.
Stage: You can tell the very exact instrument/organ position. Too much focus and precision. Best I have ever heard in digital.
Filters: They do make difference #3, gives more treble and better voices but reduces a little sharpness of stage
IMD: This DAC produces the cleanest sound when a lot of organs play together. Excellent, you can listen to metal and rock with no fatigue.

Bad things:
Stage: The stage does not have the proper extent. In my setup, normally the extend of the stage is more than 4 meters. Somehow, it was shrunk a little. However, as I said had the best precision. Another thing was that precision in depth was not so good as in width and height.
Live experience: I couldn't get persuaded that I had a live stage experience. Curiously enough my cheaper DAC does.
Voices: Female voices lacked the proper warmth that sometimes have in certain songs and they got a little "far", this gets together with the "live experience" issue
Fading: I noticed that sometimes notes are not properly fading away, especially when they have tremolo and at the same time fade away, an effect like a compression thing. This is important to me for a hi end experience, since my SE Class A amplifiers manage not to loose these fading notes when are there and this feature is exquisite to my ears.


The above was a three day test so far, I will listen to the DAC a lot more and see what happens. It seems I will search for an even better DAC. Don't misunderstand me, it is a great DAC but it was not what I expected to be, based on the reviews.

Good to read that there are dissenters here that hear cable differences. Majority on ASR do not hear the difference between Nordost and Cardas. Hard to believe but true. I suggest to try topping d70s DAC on double AKM chips. BTW I own nordost cables as well (odin interconnects)...

So you recommend using 4v into my Pre90 then?

With Pre90, 5V is recommended.

 

[glc650]

With Pre90, 5V is recommended.

Should the D90SE be set to 5v using another pre-amp (Marantz SR8012 AVR with outboard amps) or does that only apply when using it with the Pre90?

To my knowledge no other preamp has significantly lower noise than D90se. So unless you are experiencing pop sound, D90se itself is all you need.
If you still want to use other preamps, 4V is a safer option so the down stream devices won't be overdriven or cause higher distortion. You can try both and choose the one you prefer.

I have the impression that when playing music on a tidal, there is a slight jump in the sound at times, literally sounding like a distortion, I exclude a given track - I rewound a few times and if it appears at a different time than before. Do you have that too?

My new DAC arrived today. I ordered it on 8/22/2021, and it was delivered to me in Connecticut today, 8/25/2021. That's 12,873 km in three days. Color me impressed!

That's wild! Where did you buy it from?

After listening to a while, I can report that, no surprise, the D90SE sounds identical to the D90 MQA it replaced.

I also received mine in the mail this Monday, and so far it is mostly fine.

But, like others have said, I am having issues with dropouts when using it with my LG OLED tv via optical. I was expecting this since people mentioned it, but I wasn't prepared for how frequent they are, typically like once a minute or so it drops out for a split second.

What I wasn't expecting was similar dropouts when using I2S out of my pi2aes board. They are much less frequent, but still present, like maybe once an hour or so.

The only dropout free input is the USB from the same raspberry pi 4 I have the pi2aes plugged into.

 

[nelamvr6]

I'm sorry to hear you're having problems. I'm using a Raspberry Pi 4 for streaming, outputting its USB to the D90SE, and I haven't experienced any issues whatsoever. Just wonderful music.

I don't mean to pry, but why are you using a
Pi2aes?

 

[rlwings]

Loving this DAC! My god the detail, the transarancy. Simply fantastic. (Especially with Dirac room correction) ... But I am having a problem with what seems like buffer errors since upgrading to the latest driver (v 5.2) for Windows 10. When I use Windows WASAPI I get that digital 'skipping sound' errors, but when I switch to the ASIO driver it stops. I'm using a USB connection and never had this buffer problem before on my home-built ASUS i5 computer... Any ideas? (Remember I am running everything through Dirac's Windows standalone Processor. (WDM). - Thanks for any help. ---- P.S. I actually have 2 similar systems and this issue does not happen on the other one. WASAPI works on the other system. (Windows Exclusive).

 

[SoupRKnowva]

I already had the pi2aes setup and it allows for easy comparison since it drives all the outputs simultaneously. It has also been measured to have pretty low jitter, so I am surprised that it is having issues with the i2s. I will try the AES and RCA outputs into the D90SE as well.

I am just surprised it is having so much trouble, I've never had any trouble with dropouts with it on other DACs.

Like I said, it works perfectly via USB, but it's disappointing the other inputs are this unreliable. My other DAC is a Schiit Gungnir, the original delta sigma model, which even has a light that turns on if your source has bad jitter and it has to use a different PLL, and I have never seen that turn on with any of these devices either.
