Topping E30 II DAC Review

[Trell]

thx all for reply and advice for startup procedure, its good one!

You can also add a pair of passive attenuators to put between the DAC and the amplifier, and some of them have an adjustable attenuation. So full output from the DAC will not cause full output from the amplifier.

Here are the included filters:

Using the default F2, we get this wideband distortion+noise vs frequency:

@amirm notes that filter F2 is default, however the manual that shipped with my E30 II states F-3 is the default filter and it was set to F-3 out of the box...

@JohnYang1997 Are the filters in Amirm's graph labeled incorrectly? This would indicate that the default F-3 (Short Delay Sharp Roll-off ) corresponds do the slow green line in the graph.

Dear Amirm, Would you share the photo of detail your Samsung USB charger, so I can find one.

Maybe interesting for E30II users. I'm using the E30II only in DAC mode and only with my cd player via coax cable. I noticed 1-3 dropouts per cd - that is not fine for me. I asked the service at Topping for new firmware - but there is no newer official version - but the service said sometimes the jitter from source is too high - if so there is no workaround. Because my players are ok i tried another thing. My first smartphone usb power supply was to small for the E30II I connected a chinese goobay power supply with 1.5A - thats works but with this dropouts.
So I replaced on monday this thing with an Apple USB power supply - and since then - no more drop- out on coax. Apple photos attached.

Just ordered it. Anyone know why it isn't listed at tpdz.net?

Going to replace it with my Henry Audio USB DAC Mk3 wich has a single AKM4430 chip. Will I see an improvement in sound, using the USB in from my computer? Bought it to play DSD.

I have a DVD player, my topping D50 cannot lock coax signal, so I bought a E30II for DVD, it locks signal success withouth any dropouts.

Yes - perhaps it depends what power supply is used - looks like that is important for proper operation. Would be clever if Topping add a ps by default.

E30 ii was programmed for maximum compatibility

Thank you for the advice, I found a samsung 5V adapter model is EP-TA50UWE and an Apple 10W A1357, using the USB tester test results are as follow.
