The New King?

[Veri]

I must have missed that, sorry

Edit: up to 5V only... why not more?

...why more?

 

[Oukkidoukki]

Johnyang, have u listened se against d90? Can u hear better separation, finesse and space?

 

[RickSanchez]

...why more?

Isn't it obvious?

 

[Evgeniy]

As far as I know X26 Pro cannot run on Asynchronous mode, so D90se is always cleaner?

what mode use DX7pro , when receive signal from USB and from spdif (coax/rca) ?

 

[devink]

...why more?

I would actually like the option to have less since 1-2V is optimal for my particular speaker setup.

The RME ADI-2 handles this the best of any DAC I’ve seen since it’s volume control incorporates a couple relay switched steps.

 

[raif71]

...why more?

Amps like Topping L30 and Singxer SA-1 benefit more from higher output voltage coming from DACs (from my understanding)

 

[gonzoucab]

The big question is WHEN Topping will release mono power amplifiers in class AB (with GaN technology?) that will surpass Benchmark AHB2 power amp in measurements and sound?

I am waiting

IT MUST BE DONE, PERIOD !!!!!!!!!!!!!

Who thinks the same give me like

When?

@JohnYang1997 please share with your friends at ASR the d90se anticipated debut date?

If everything goes as planned, about a week later.

I agree. I'd also like to see these manufacturers (I'm looking at you, Topping and S.M.S.L) spend more time tightening up design review and testing, manufacturing processes, improving QC, and refining existing products instead of constantly releasing shiny new bits to try and keep people chasing the carrot.

I second that...

The new D30pro just released has issues (fortunately not my unit, but other people's units):

Seem to be mostly firmware updates, which if the manufacturer gives users a relatively easy way to update firmware (like Soncoz does with the SGD1), and issues the appropriate firmware updates, would be fine. Sadly that is not the case for all manufacturers and products. For the SU-9 i think wolf required some specialised connector or cable to update its firmware.

Thank you, John clarified this in the other thread.
I tried D90 and bought D30pro, so I like Topping products much.

QC and testing take time and sometimes there is too much rush and competition, which are not necessarily good for the end user.
For example, a friend of mine is a DIYer and discovered that his D70 was peaking 1V when sample rate was changing (see the left of the attached picture). He had to return the D70.

Just my 2 cents, as I said above, I appreciate Topping DACs

Seems like the best performing AKM filters are the (usually) default min phase fast and the linear phase fast filters. My guess is when measuring the D90 (and probably the D70s and Loxjie D50), Amir used the default AKM Filter 3, allowing us to compare the optimal filter performance of AKM and ESS across the frequency spectrum (since the Okto DAC8 uses one of the optimal filters by default). Doing this shows that ESS's best filters are a clear step up from AKM's best filters. This might be down to different delta sigma modulator designs. I know ESS's modulator has a lot of clever technology built into it.

 

[half_dog]

Try 19.3k tone at 44.1k sample rate and 21k tone at 48k sample rate on ES9038, with 192k recording rate. The differences among different filters should be bigger. Specifically, try to find things on 68.9k in the 44.1k result and things on 75k in the 48k result.

I have chosen 1kHz to be comparable to Amir Wolfx measurements from both D90 versions
Here are the measurements you suggested. That's only from D10s, mine E30 is not with me right now.

Thanks. These frequencies are selected to overcome the measurement limit of your recording interface. Looking forward to see your E30 filter measurements.

@JohnYang1997 Will the crosstalk measurement of the production version of this device be the same as that of the prototype version?

[dmac6419]

Is this Topping's response to Gustard X16's measurements?

I wonder what is the difference between this and dx7pro ...

Yup

 

[Ron Texas]

We are past the point where even $100 DAC's measure so well that further improvements in measured performance are for bragging rights only.

 

[gvl]

I mean. Maybe the D90 will have a sync async switch but in the end, the science would indicate it could hardly make for an audible difference.

So I tested Sabaj D5 against Topping Dx7 Pro, feeding the same signal via USB, the latter running in sync and async modes through the Atom amp, using quick AB switching and now I'm convinced that the differences I thought I heard between the sync modes on the Dx7 Pro were largely imaginary as even sighted I can't detect anything of significance. I still like the idea of synchronous operation though
