Un maravilloso sonido, sin embargo la construccion en general es buena pero la placa de atras del dispositivo se termino despegando, al parecer usan una resina y se cayo la tapita entra algo a precion asi que en general se mantiene. En mi caso le puse un pequeño magneto par sostenerlo con el celular con safemag, pero el magneto resulto ser mas potente y generando mas fuerza que el pegamento de la tapita. Nada del otro mundo para mi termine pegandolo denuevo. Y cambie la posicion del magneto, pero algo a considerar. Sin embargo el audio que entrega y la potencia que es por lo que se compran estos dispositivos es muy bueno. No me arrepiento pese a lo sucedido. no lo doy ese 5 star solo por ese problema de la tapa posterior.

I have a Sony nw a306 that I bought for streaming. It's a great player except the volume couldn't compare to my nw a55. I needed an amp. I researched quite a few and new all about the shanling products. I must say this little dac/amp blew me away. It says quality all over it. It identified every format correctly and it's very easy to use. Wish it came with a small case but I think it's still a bargain. But the sound is beyond fantastic. I highly recommend it. Since I just received this unit today, I'm not sure about battery drain, but if it's an issue, I'll follow up.

Works perfectly. Nothing else to say.Works with a normal USB cable as well.

I have an iBasso DC04 (non-pro) as well as an iFi Hip Dac 2, but I don't like the separate volume app that the iBasso needs on Android, and the Hip Dac is just too bulky and overkill to drive my Audio64 U4s IEM's. I had read some good reviews of this Shanling, and picked it up on Prime Day.At first blush, I though the performance was very good, and the OLED with integrated volume buttons were really nice improvements.But then on critical listening, things went off the rails. Right from the start, I noticed that the OLED seemed "stuck". It wasn't changing on my Pixel 8 Pro as I went through different tracks in Tidal, despite the fact that Tidal had access to the DAC. Everything was showing as 48 kHz PCM. After rebooting, plugging in and unplugging, I did get it to recognize one MQA track as MQA, but subsequent FLAC tracks were showing as MQA at the wrong rate.Then I connected it to my Windows laptop. It took a ton of trial and error to get it to properly change modes between tracks, but I got there, eventually. Tidal needs exclusive mode (not surprising) but apparently, the DAC gets very unhappy if you pass MQA to it for decoding. Weird. But, hey, we've got it functional, right?Well... I guess. I started messing with the filters because some tracks were strangely bass-heavy (as rendered by the DAC) with hollow mids. Tinkering with the filters made the inverse possible, but there were some tracks that just didn't sound right. I started doing A/B testing with my other DACs to confirm, and it was as I thought. There doesn't seem to be a "don't color this at all" filter or setting.As much as I like the display and the price, I think this is going back.

Warm, rich, textured and meaty delivery. Oled screen is very informative and helpful. Plenty of power for Shozy P20 planar and Aful Performer 5 iems. Would not hesitate to buy again.
