Topping E30 II DAC Preamp Audio Decoder- 2xAK4493S Hi-Res XMOS XU208 DAC 32Bit/768kHz DSD512 DSD Direct Mode for USB/Coax/Opt Inputs RCA HiFi Stereo Digital Audio Decoder(Black)

Coming from a FiiO D3 I'd say this is a really good upgrade. The sound quality is fantastic, I can't imagine anything sounding noticeably better. The feature set is also really nice, especially the auto on/off and pure dac features. I'm using the optical toslink input with a mac mini running debian Linux and the Logitech media server software. From this I play local flac files, CDs, and hi-res music from Qobuz and I really couldn't be happier with the results. I did want to use the USB input instead of toslink but the auto on/off doesn't seem to work in this mode, but that might be because of how the USB audio output works on my setup. Overall I'm happy I bought this and I would recommend it to anyone looking for a high quality dac. EDIT: Still using and enjoying this DAC. Just wanted to update that I found a way to get the auto on/off working on Linux when using USB. Using the lsusb command I got the idVendor and idProduct of the DAC. Then you edit/create the file /etc/udev/rules.d/90-usb-power.rules and add the following line: ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="152a", ATTR{idProduct}=="8750", TEST=="power/control", ATTR{power/control}="auto" Those numbers should be the same for you if you have this same DAC so the lsusb part can be skipped. After that I rebooted the system and then the DAC was able to go into standby via USB.

The Topping E30 ii DAC definitely improved the output quality of music from my Lenovo Yoga laptop. I store all my digital music in lossless format, I don't use mp3's due to the compression & lossy algorithms. I really appreciate being able to get the best out of my music collection & the Topping does just that. I realize everyone doesn't feel the need for the highest quality music reproduction, to some storage space is a concern. But if you're someone with a keen ear & an audio system that reproduces the fine nuances many of us appreciate & demand, a unit like the E30 ii is well worth investigating. I wish I could rate it 4.5 of 5. 5 for quality of reproduction & ease of use, with a small ding for the setup process & supplied documentation.

I have a $3,500 Cambridge DAC and I would say the Topping E50 is very very close in sound quality to that DAC - I’ve already recommended this DAC to my friends. Thanks

I use a DAC to run the optical signal from a Samsung smart TV to an older, analog speaker/subwoofer system. I bought a Dingsun off Amazon (about $23), and it worked fine -- but the remote had only about 5 steps, so you'd quickly jump from too quiet to way too loud. Figuring that you get what you pay for, I sprung for this. The sound is perfect and the remote is a dream come true (I sit only about 8-10 feet from the TV). Later, I found that there is a Topping E30 "Lite" that would have served my non-audiophile needs and saved me about $30, but I'm still very happy with this purchase.

I needed a decent DAC to stream music into my stereo amp (a very good one, but old enough not to have an internal DAC), both from my MP3/FLAC library, as well as online sources. (If you're an "audiophile", you can stop reading now.) So I'm using optical (or coax) in, not USB. The headline specs are 768kHz/32bit max, but read carefully, that's for USB in. With coax/optical in you get 192kHz/24bit max. All I care about is CD quality or better, since like most people I can't hear the difference with anything higher, so these specs more than meet my need. Specs aside, how does it actually sound? Very good indeed. The sound is perhaps just slightly different (wee bit brighter) from my very good CD player (with Wolfson DAC) -- but I'm not sure I could tell which is which with a blind test. I'm quite happy with it, even when I'm streaming FLAC-source classical music that I'm fussy about. I think 100-150 is the sweet spot for DACs: if you choose carefully you can get a very good one for the money, and paying more isn't necessarily going to give you better sound. Do your research carefully, and enjoy!
