Just got the topping e30 in, so far it’s pretty nice. I at the moment like it with the short delay slow roll off filter. I think it’s more balanced than the d10 a bit, and it’s more refined sounding too. Volume control works as intended from the remote. So far have only used USB in and that works no issues, thesycon drivers and no issues there. Using the included dc to USB cable and powering it off a nicer phone quickcharger and it does the job well. I think it’s better than the d10 detail wise, not a massive jump but something that I do think is a clear improvement for the price
Right now I have been using it on the Viva Egoista 845 to a 1266 Phi TC, will test on other setups when I have time, this is just a quick listen with whatever I had nearby me at the time.
So far though from the short experience, this is a worthy upgrade to the d10 imo, and def worth your consideration for the sound and features it can offer for the price. The only thing the d10 has over it imo is a bit higher quality display (don’t really care that much tbh), and optical out if you need it (but personally more people want optical in anyways)
I will spend more time with it, but most likely won’t give more impressions on it unless this becomes inaccurate lol. I haven’t tried dsd with it yet (natively at least), and I have only used one amp and headphone so don’t take this as my final thoughts or anything. The reason I have this is a gift for a friend, but I was going to try it out, I ain’t turning into a reviewer or anything lol
