Topping D70 DAC

[yue]

If you happened to purchase a DX3Pro from Topping, you'll see a small flyer which intros their latest DAC product.

It looks nice, but I am replacing my Topping D30 with the Khadas Tone Board DAC which has a THD+N of 0.0003%.

well those values are tested under different conditions. So does not mean much.

Khadas Tone Board DAC looks good but it uses usb power, which may be super unstable.

Any idea on price?

My tone board is on the way and I'm planning to power it with a linear supply which I happen to own one. I'll make a subjective comparison vs direct USB connection.

I have certainly not heard any audible problems from USB powered DAC's in the past.

well, if you look at the thd+n vs frequency, you will find that tone board does not behave that good compares to topping d30. I am glad that topping d70 claims <0.0006%(20-20khz). This is much useful than thd+n@1khz.

Nope, the khadas DAC has better measurements than the Topping D30, so I have no idea what you are talking about.

With coupons and discounts you can get it to as low as ~168 USD. Purchasing through the aliexpress phone app gives a 2 dollar discount I believe.

GALA DAC has the best measured THD+N vs freq performance on this forum.

If you mean Gala DAC, I don't have a plan to measure it at this time. I have so much other gear piling up that I need to test those than re-testing that unit.

What I mean is I don’t really trust the measurement from manufacturer.

Got it.

How is THD+N different from SINAD?

The Khadas DAC was at 110 dB which is better than the Topping D30 and better than the Gala DAC.

110db is only at 1khz

There are no Topping D30 measurements there, proving my point.
