Topping E30 DAC Review

Koeitje said:
Seems there is no power supply included? @JohnYang1997 how much power does it need? Can you power it over USB and use SPDIF? Not sure if I have a 5V power supply laying around, but I have plenty of USB chargers.

200-300mA. You can certainly power it from PC. Oh but you have to use the round 2.1mm 5V input jack for that. The usb input doesn't take any power.

Have you considered making 4 channel stereo DAC that would allow for easy integration of 2 subs?...
What I'm proposing is a product identical in functionality to MiniDSP U-DAC8 but with 4 channels and better specs.

Won't go mainstream, at least not while most believe their mains are always in the perfect spot for great sub-bass :facepalm:. The current solutions I see are miniDSP nanoDIGI (use DAC's of your choice) or SHD series (use DAC's of your choice on Studio version, and or built-in DAC's on SHD version).

I see the facepalm and respectfully wonder why? To each his own for sure. I feel I may have come off too opinionated earlier, too, when I said I don't think subs are necessary for music. Hey, I say do whatcha want, and if you like a lot of bass, there is nothing wrong with doing it your way as long as you don't annoy your neighbors. :p But in my opinion.. I go for the most realistic presentation possible. I am trying to recreate a live concert where there is a band, musician, singer, guitarist, symphonic orchestra, etc. on a stage in front of me. In my scenario, all sound is originated from in front of me and so that is where I prefer my speakers (of all size) to be.

I agree that the story is completely different for movie watching, etc.. but again I think AVR's do just fine there as a DSP, DAC, probably even power amp. For the crazies out there that have 10 subwoofers... you do you. I'm aware that it takes serious know-how, effort, and hardware ($$) to do it right. Most people simply don't have the means for such, and with the law of diminishing returns, it's just not appropriate for the mass consumer market.

Respectfully disagree on most all levels. This site is after all devoted to science, not so much about subjective opinions.
1) Your input infers sub integration as being loud, expensive, overly bassy, localizable, unrealistic, etc. NONE of which are true when properly selected and setup. In fact quite the opposite will be true as compared to incorrectly placed mains/room problems/etc. As regards to cost, my entire combined stereo/HT system was about $3000 USD total (of course I built all 5.2 speakers myself to get this cost point :)), and is ALL consumer grade stuff. It does take some effort setting it up properly, but for that effort I have a measured relatively flat 17Hz to 18KHz in room response (along with all the other important factors measuring well).
2) You can find out about and how to do inexpensive room measurements at this (and other) sites, which scientifically prove the already very well known bass response issues in rooms (as well as how to fix such issues).
3) Also look at all the measurements of AVR vs dedicated stereo equipment reviews right here on ASR, which pretty much prove the point that most AVR DAC's/amps are simply not up to the task of high fidelity sound reproduction. Something I proved to myself after I added a 2-channel system to existing AVR HT/music system, sharing most other components/source/speakers/subs/amps (was not expensive to do; $600 preamp with sub/HT bypass support, and an $80 Topping D10 DAC). After the first A/B level matched sound comparison I was simply awestruck what science vs. ear can do for the ear!

Anyways enjoy your system....back to regularly scheduled non-subjective thread. I was simply trying to get the person who responded an affordable DSP/sub-integration solution using the E30 DAC's. I am currently on that path myself, getting my 2-ch subs integrated in the digital vs analog domain (same subs used for HT are already integrated in the digital domain of course).
 
For people who asked
5 units tested. There's one unit I tested twice in TOSLINK I think..

That's somewhat unfortunate, so it occupies 2 USB ports when used with a PC/USB input?

I get it, but having one cable for power and data is convenient given the USB power is sufficient. Do you know if there was a technical reason to not allow the USB input to also power the unit?

Maybe it has to do with not allowing PC noise to pollute the input. maybe.
 
There should also be PSU in the package, not just the power cord.
