You can have bit-perfect/exclusive mode with all devices. No exception.

At least 'till people start doing mods to their own ears...
Hi all, I'm a happy owner of a Topping E70 in the market for a new amplifier. I'm currently considering the AUDIOPHONICS AP300-S250NC (https://www.audiophonics.fr/en/powe...ifier-ncore-nc252mp-2x250w-4-ohm-p-18419.html), but one line in its description gives me pause:
"This amplifier does not have a decoupling capacitor, so it lets the DC component of the signal through. Make sure your source has no DC component present at the output. The DC protection of the module switches on at 12VDC which is very permissive."
I don't really know anything much about this matter, if at all, so I'd appreciate some advice on whether the E70 does or does not have any DC component present at output. I believe I read somewhere else on ASR's forum (can't find it now, of course) a statement along the lines of most, if not all, DACs and preamps having this decoupling capacitor, but I'd really appreciate confirmation about the E70 in particular, please.
I haven't heard back from an email I sent Topping as yet, so hopefully I can get some sound advice from you kind folks. Thanks everyone!

The DC protection for amps with DC coupling design is their responsibility. It does not seem logical to me to ask the connected equipment to guarantee the absence of DC, because, although it must be so, this does not protect against a failure in the amplifier itself. The allowed level of 12 volts DC seems excessive to me.

Hi @Yannick! Welcome to ASR.
You're buying a 500€ Amp for your 400€ DAC.
Please consider also purchasing a 20-30€ multimeter. It's an extremely useful tool with which you can measure DC and AC voltages yourself.
No more relying on what other people say your equipment may or may not do. With it, you can gather your own data.
IMO, a must-have accessory for any audio enthusiast.
I use an Aneng AN870 and it's been great.
Thanks everyone for your replies. Looks like the amplifier search will need to wait a short while: I'm off to look into multimeters! Many thanks for the suggestions, it can be overwhelming when first jumping into the more scientific realms of audio so it's great to receive such a warm welcome.
All the best to everyone.
All the best to everyone.
Just updated my E70 with firmware v1.04 and notice there is a new parameter in the setup menu - "b" with various values up to 15?
I thought I had seen an explanation of this somewhere but now can't seem to find it. I understand it has something to do with the SPDIF interface which is how I mainly feed my E70/L70 stack plus Edition XS/Fiio FT5 set up using the SPDIF coax output from my Fiio M15S so it may be pertinent to set it to a suitable value?
Can anyone lighten my darkness please?

Sorry, just re read your post. The 1.04 firmware update is for the E70 ( ESS chip) I have installed it on mine and it's fine. I have asked if it functions on the E70 Velvet (AKM chip). The prefix ( V ) on the firmware version causes confusion. Thank you so much BR

Many thanks for the pointers and I can get some understanding of the function.
Strangely enough when I went through the settings following the install of V1.04 the value was set at maximum 15 and not the 5 default? Have changed it to 5 now and will see how it goes.

I've spent quite some time trying to understand what that advice meant in practice. Found some post going into details, so technical that about a third of it entered my mind and not much stayed. So I tried to look at it another way : I can't say that I found someone complaining online that their speakers got damaged because of this specific reason with these audiophonics power amps. And yet I've seen a huge number of people saying they use them, in a good variety of setups, and with many different sources.

So where is the 1.04 firmware?
I have the TV issue as well.
Any help is appreciated!

So no official link? Im not keen on using something from what looks like a random Google account.
There's this official link, which will get you to both Windows and Mac versions of both the app and firmware V1.03 https://www.tpdz.net/newsinfo/778017.html
If you want 1.04, I can tell you that I had no problems with the file from the Google Drive link.
Yes, I understand your caution but I did the risky bit and tested it for you - had no problems same as the other user above.
