I have E70V. So, Velvet is much, much better! 
I've been using the E70 for many months just like this and haven't had any issues. PC/Bluetooth > E70 > Amp + Sub. Amp gets XLR and sub gets RCA.Just would have loved to hear back from someone who actually did it (or a very similar setup)There are a few testimonies here and there, but they are sparse. My case use is probably be the same (PC or radio receiver -> Topping Dac/Preamp [so it can auto/on off and trigger on/off the power amp]->Rca to active subwoofer ; XLR to Power amp ->speakers).
I think it could be done with the E70, E70 velvet, D70 pro (Octo and Ess versions), the DX7Pro+ and the Dx9 (at least, I might miss some - must write down somewhere which ones have simultaneous RCA&XLR out, auto-on off and 12v trigger out) ; but it's way too late here for me to have the concentration to compare specs, functions and measurements to see if what's worth between going 400 (E70) to 1300 (Dx9) bucks and everything in between

Yikes!Nice. Was about to say "that's the setup I think I'll aim for", then I stumbled on this thread and post which are scary as hell when your planned use case is "one signal wakes up all the rest of the chain automatically"![]()
The short answer is yes the E70 will oversample just like the cd player. Almost certainly better but possibly really really "just like".I have a question.
From what I read, CD players use multiple oversampling in their internal DACs to output the analog signal.
If I output such a CD player to the e70 via the optical output - Toslink or coaxial, the Topping e70 recognizes it as 44.1 kHz.
Does the Topping device perform oversampling within its circuit? (I don't think so ?)
"What is oversampling in CD player?
The audio industry has now standardized at an 8x oversampling rate, which means a CD's sampling frequency is increased to 352.8kHz before it enters the digital-to-audio converter. This effectively moves the aliasing frequencies to values near 300kHz, much higher than the original 22.05kHz."
Oversampling is an internal function of Delta-Sigma DACs. There is no reason why an external DAC, if it uses it, should not apply it to the digital stream that produces the CD transport.I have a question.

Thank you.Oversampling is an internal function of Delta-Sigma DACs. There is no reason why an external DAC, if it uses it, should not apply it to the digital stream that produces the CD transport.

I need a much more in-depth explanation of those "dynamics" for the quote to have any hope of making sense.
For those interested in deep tech, we even design digital clocks that will follow the sampling frequency in the music and "down-clock" when receiving a low-resolution file. For the non-techie, the result is a far more natural and "analog" sound as well as an unbelievable soundstage and realism.
You still don't substantively answer the question which is better, which combination is more appropriate?Thank you.
To simplify matters, if I find a CD player with a correctly measuring DAC, with a chip from the same company ES (An example of a similar chip: The Denon 900NE uses ES9018K2M DAC with Denon's AL32 processing plus digital filter) - I assume 8x upsamling to 384kHz
Will the sound be more correct on the analog output or from the Topping E70 DAC using Denon as a transport for the digital output? - 44.1kHz
Has anyone tried to measure it, how to connect a CD player better?
Very scientific statement! This is what I expected, as befits this forum. Think about it, producers are very bored and oversample CDs by eight timesYour actual hearing most likely won't give a rat's a¤¤, and the improvement being measured will probably equate the manitude of an ant farting at the opposite end of the solar system.
Whether you can get rid of your nagging doubt is a completely different matter![]()

Yes!Can i have bit-perfect/exclusive mode with this device?
