Nice write up. You're probably the first in the world for HC3 impressions. Could you confirm if the AK HC3 is warmer than the AK HC2? As you have stated one of it is brighter, but it seems a little unclear which one. I'm looking for something with more bass than the PEE51 which is a bright...

Any impressions (with comparisons among similar usb c portable dac) of the HC3?

I've been using this driver for 2 days. The issue is still there. Will there be a fix for this as it feels as if the shanling ua2 plus windows driver is half-baked. It is too easy to reproduce, just connect a shanling ua2 plus into the computer while spotify is already running, switch between...

@Shanling the windows support is pretty buggy. Before and After downloading the Shanling Windows driver from the official shanling website... sometimes I've to restart apps just to get audio output from the app... E.g while listening to spotify or playing games on my speakers, I connect the...

Interestingly I did find that my UM 30 PRO had expanded soundstage and separation with the same cable on balance, compared to unbalanced. But i preferred how the bass and drums sounded via the unbalanced port as there was more impact, the overall sound was thicker in the unbalanced port. The...

Thanks. I'm concerned that adaptors will degrade the audio quality. Do you have adaptors to recommend? Unfortunately I've already purchased the Shanling UA2 plus. So it is either terminating the wire and risk oxidation of the wire or use adaptors... Or stick with 3.5mm.. Do you guys not make a...

@Shanling can we know the difference between the unbalanced and balance circuitry in the Shaling UA2 Plus? From the website it seems to be wording it in a direction where only the Balanced 4.4mm port uses the dual Ricore AMPs. Does that mean that the 3.5mm port is inferior and is using a...

Thanks for the info, just to confirm, the 2 silver litz cable you've mentioned are the same brand and model just with different plugs (2.5mm and 4.4mm)? Do you mind sharing a link to the adapter you're using? I'm guessing it is one without a cable, basically just a hard adapter. For the...

Thanks for the info, would you still recommend these adaptors that might still color the sound, over the direct 3.5mm unbalanced variant of the cable? Maybe I should just go for the 3.5mm variant of the cable since its the most widely supported format and not have to worry about adaptors...

2.5mm iem cable converted with adaptor to 4.4mm, will this degrade/affect sound quality as compared to getting a cable with a default 4.4mm plug? This is because I can get a REF 8 ALO cable at a good price, but only in the 3.5mm or 2.5mm variant. I do not have a source with 2.5mm, my source...

Does anyone have recommendations for cables that will fully cover the shorter ports of the UM PRO series iems? I've tested the Fiio RC cables but both of them didn't fully cover the port, leaving the gold connection partly exposed. I'm afraid if sweat or water gets in there, things could get...

Interested to read your review and comparisons with other USB DACs such as Shanling UA2, Questyle M12, Lotoo Paw S1, Dragonfly Red, Dragonfly Colbat, etc.

Does the PEE-51's performance scale with the amount of power supplied to it? I've auditioned it with my LG G6 smart phone, but find the PEE-51 to be a little weak in the low frequencies. Wondering if its because my phone which is already about 3-4 years old, have outdated hardware that might be...

Interesting, I'm actually on the look out for a USB DAC that is slightly towards the warm side with punchy low end bass slam. Sounds like the M12 might fit my taste. I've auditioned the PEE-51 and found it to be slightly polite on the low end, if it had a little more bass slam punch it would...

Very interesting findings you have there. So you're saying you found the Questyle M12 to have more bass slam, low end impact than the Shanling UA2? I generally have an idea of what you might mean by bombastic, but do you mind going into a little more detail? Which part of the frequency is...
