hey, that's a relief. Need some more info though. EDIT: Here https://www.head-fi.org/f/threads/lm4562-lme49720-lme49860-do-they-sound-different-to-you.521972/ LME49720 = LM4562 < LME49720HA But LM4562 and HA are physically the same.

Thank you very much for pointing it out, as I didn't noticed it since I was busy when it arrived, and excitedly opened it without reading thoroughly. I just reopened it as of post time, just as I read your replies. The whole moment was a lie. In the first place, I ordered the wrong item...

is it different from what I said LME49720HA? I don't get your question.

My LME49720HA just arrived and I was amazed by how RS (seller) packaged the item. From a 13x10x5in box to a <1cm item.

both can used as DAC. It's just that Walnut V2s has audible clicks/pops issue if you use so. No known solution at the moment. I ordered an op amp, arriving atleast next week, ill try if changing op amp will affect the issue. But overall and except it, no problem.

Thanks for that. Seems like it's safe for me to try my incoming LME49720HA, then sell device later (if decided) without affecting the audiogon scale. :evilgrin: country?

I was really afraid that my question wasn't clear. I'm sorry for that. What I mean is, let me give a scenario then. You moved/replaced the stock op amp with OPA2604, then after you tried it, you reverted back to the stock. You sold it to me. Should I be able to recognize that you already had...

What are you after, just the voices/language?

For those who've tried to switch op amps, is it noticeable that you changed it? I mean, the aesthetics? I mean, the scratches, etc. (Sorry, Im really not sure what words to use.) EDIT: You just posted while I was writing. May ask you the question above?

Envy. Will look for V2s Z1 trade.

So just to confirm, Z1 as dac has no problems about pops/clicks? Yes. I will personally confirm that.

more info please? well, I'll google later.

Ahh.. Walnut V2s has really this issue as DAC. I already tried everything I can, from drivers to latency fix, to etc. I hope somebody can fix this.

Turn ON your walnut Pause Insert USB Cord On windows, right click on Volume Icon in System Tray Choose Jiebel17 (forgot the exact number) Click Set as Default Open a music, insert your headphone in Walnut and listen Tell me what have you observed. Thank in advance mate. From the seller's note:

Envy. Can you do me a favor? Please try using it as DAC. I will earnestly wait for your response.
