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.

Windows 10 Pro x64 (desktop), it works. Windows 7 x64 (laptop), it works. On yosemite (laptop), it works. One problem, audible clicks/pops. Oh, so it was latency issue? I'm using Foobar, and tried WASAPI and ASIO components to no avail.

Foobar is what I use. I installed those components as you said but it is still there. Normal - pc side or walnut's? I don't think so. Will try more troubleshooting tomorrow.

Good to know you don't have this issue. I'll try to burn it in first.

Oh, Z1 also? Then, burn in it is.

Do this, let's just try: Turn your Z1 ON first. Pause. Insert USB cable. I assume you're doing otherwise. V2s, on the other hand, can't be detected as DAC when you first insert cable, and pause. and btw, I have to share that my V2s as dac has audible pops/clicks/cracklings (or whatever you...

I tried V2s as DAC on windows and mac, sadly, there's a lot of audible pops/clicks/cracklings (or whatever you call it), otherwise it was good. Tried three cables, including stock, but still there.

No, I don't have both. That is a very helpful info. Thank you very much. Have you ever tried it as a DAC? I have no idea how to. I tried but no.

so far, I have a hard time recognizing eq and their changes. <2 hrs of playing

as an amp, audio jack. as a dac, usb. I haven't played with my V2s yet, I just received mine 16 hrs ago, and just tried playing for about an hour. They said Walnut V2 upgraded has DAC but meh; V2s has DAC, but I haven't tried it yet personally.

Technically, no. I am from Bukidnon. I will wait for your advice then. I haven't played with my ZST yet, as I just received my V2s and monks+ yesterday (16hrs ago as of post) and I'm spending the past few hours (accumulated 1hr+) testing. And by the way, I was in this thread for Z1 vs V2s...
