Topping E70 Stereo DAC Review

[CALCULATOR]

I do agree, measurements support that we shall not be hearing difference, it is all psychoacoustics.

Between R2R and Delta?

Hmmmmm

Maybe the Gustard and the Topping sound the same

I don't frickin know anymore

But it sure looks super cool check this out

great setup!

Calling on experts, I have received E70 Velvet today and connected it to the RPI4 with moOde player streaming to it. I checked that the Power Management mode is set to A-1 which should be sleep when no signal is present, however, DAC does not sleep even after 60 mins with no music streamed to it. Any thoughts on what I am doing wrong?

As long as USB is active, E70V will consider input as active. If you can shutdown USB port on RPi, then E70V will go to standby after 1 minute.

As long as USB is active, E70V will consider input as active. If you can shutdown USB port on RPi, then E70V will go to standby after 1 minute.

Also you can see the same behavior with almost all USB DACs connected to windows PCs or RPI

My benchmark was modest JDS Labs Atom+. I had Atom+ connected to the same USB cable before I bought E70V and it would sleep in exactly 60 mins after the RPI moOde stops playback. I assumed that it is normal behavior for all USB DACs. E70V sleeps on OPT and COAX when you stop the playback, just not on USB.
My question if moOde Player sends a "keep-live" signal that E70V senses and if that could be turned off? I know Kodi does have that option.

I would like to be able to do the same with my Shield but even I configued USB to be off during sleep, E70V remans active.

 

[smokey_mountain_asr]

I have tested on Shield, PC and E70V does not sleep, period. Basically there is no scenario that I found when E70V would sleep, only when I completely shut down the PC or Shield, only then DAC sleeps, which makes it useless for my use case (I was trying to use it as preamp to control the power amp). Topping almost made it right 12V trigger, signal sensing, but something went wrong along the way in implementation

A70(V) should auto select active input... Doesn't work for me either. Only what works, most of the time, is waking up if Bluetooth was last selected input and I then turn on bt on my phone. Probably it will wake up when detectcs active USB.

I would not say it is wrong
It just detects USB 5v power rail

 

[smokey_mountain_asr]

I am not seeing a setting in moOde Player to shut off USB power when music stops playing. I am talking to the moOde developer but I doubt they can implement that.

I have an E70 and would like to control its volume using Moode. Moode can do this using the volume control of the ESS9028, but there seems no way to control the pre amp gain.

Is there a relevant difference between using the volume control of the pre amp vs. setting the pre amp to 0dB (DAC mode) and using the volume control of the ESS9028?

Cheers, Joe

the pre amp is also using the volume control of the ES9028, so there's no difference.

Greetings, ladies and gentlemen.

I've decided to write my first post here, I'm a former audiophile hi-fi player with a technical background and I've kind of gotten back into it.

I have been passively reading this forum for a long time now, thanks to which I managed to save a lot of money to get a picture of what is on the market today and for how much. My summary is that DIY is no longer worthwhile, as I discovered Topping and other Chinese manufacturers, who have come a long way in the 7 years since I haven't followed hifi.

Gradually, out of curiosity, I tried D10s, E30, E50 until I ended up with E70, which fully provides me with really perfect performance at a still affordable price.

I would certainly be interested in the newer D70pro, but I don't think that the difference in price would bring me such a big improvement.

I hereby thank ASR and all those who make it up, for the fact that such a place exists. I sent some money to AMIR for support, because I think this was really missing in the swamp full of paid reviews by advertisement-paid or incompetent peoples in magazines or on the Internet. I consider myself technically advanced, I have been involved in audio development and service for 25 years.

Thank you gentlemen and I apologize for my bad English, it is not my native language and sometimes I have to use a translator.

Welcome to the club.

What did the E70 do that the E50 didn’t?

 

[Dawsoo]

Hi,thx for invite,
Practically everything, from sophistication, connectivity, parameters and better fulfilled ideas of my purely subjective perception in my lineup, the differences are really small but they are there.. E50 vs E70, actually measured by me at home cosmos ADC both RCA output 24/44,1k on 1kHz @-0,1dbFs.

*** I'm keeping both, they're both top DACs, I'll use the E50 at work and the E70 at home.***

 

[GPJ]

That's great you are enjoying your E70. Ever since the early E30 (all AKM), I haven't noticed any audible differences between the E30, D30 Pro, D50s, E50, and E70, or Sabaj A20D. Sure there are feature differences, but all the above mentioned DAC's are transparent IME.

 

[jbaumann]

the pre amp is also using the volume control of the ES9028, so there's no difference.

Ok, but when I use the volume control of the ESS9028 then the volume that is shown (and can be changed with the remote) does not change. What, then, does this volume control?
