Hi, I'm interested. How much would it be the shipping to Switzerland?

Thanks. Have you ever tried calling while running? Was acceptable the noise of the surroundings for the other person?

Hello everybody, I am looking for a good pair of Bluetooth earphones, not necessarily true wireless. They must be comfortable enough for running and with a decent quality mic. Let's say the person on the other side should have a comfortable call. Now I've got a pair of anker soundcore spirit...

Ok, but what about through cable?

Greetings everybody. I've recently received a huawei P9 and use meelectronics m6 pro earphones. I'd like to improve the overall sound quality and I was thinking about a portable USB-C portable dac like this one (link). Do you know if it's compatible?   What would you guys suggest?

Hi everybody, I was checking the advanced audio properties for audio devices on my surface pro 3 with windows 10 and I found out that the audio signal is alsways streamed at 16bit/48kHz.   Do you think it's possible to stream at least at 24bit/96kHz? In particular, I'd like to stream bluetooth...

Just read your M6 pro review and you're definitely less enthusiastic, I mean waaaaaay less, than what you are for RE00. :) I had a sennheiser IE8, if I remember correctly, and I found it bass-heavy, while I simply loved a pair of PL-50 that I lost (damn it!), so maybe the 00 are a good bet for...

Hi everybody. I was almost going to place a massdrop order after reading the review, but I've got a couple of doubts. In the under 50$ field there are other interesting candidates like mee audio me6 pro and soundmagics, rich in accessories too. In particular, what I'm mostly concerned about is...

I'm really interested in your experience with the hifimediy dac, since I'm considering to buy the one with the headphone out LINK. Keep us updated.     Thank you. I'm sure these amps are great but really out of my budget.

  Gosh, I'm sorry, however thank you so much for your reply. And about mini headphone amp in general, what would you suggest?

Hi folks, my xperia sola has really horrible sound IMHO and my FiiO E5 catch some interference when the mobile data is active, so sometimes I can clearly hear some "bip, bipbipbipb biiiiip". Really annoying.   I was considering the hifiman HM-101, do you know if it could work or if it worth...

Quote: Measured also the offset voltage. I measure something like 2.7mV, so really really low DC voltage, it should be ok, right?   A thing that I'm not sure about is if every pin of the U3 is soldered.

Quote: The pics of the clock:     As you can see the clock doesn't seem to have solder on its top.   Sorry for the noob question, but how can I measure the offset?

Quote: Infact I've just plugged it in again and the pc recognized it immediately. Thanks! Quote: Some pics:    I've just tested the voltage between a pin of the U1 and one of the U3 chosen at random and found continuity.

Quote: Ok, this means that the U1 works perfectly, right? A sidenote: the usb dac got installed every time I plug it in the pc, is it supposed to do so?   What do I have to check about the U3? The solder joints? Some voltages?

Hi folks, I've just resoldered the main chips: U1, U3 and another couple because time ago I burned them accidentaly with the multimeter while the dac was on. Now the dac got immediately recognized by the pc when I plug in the usb, but I can hear no sound, not even a hiss/buzz from the...

Quote: Ok, can you please show me input and output for each buffer chip? Thanks.

Ok, I've got the opamp but not the buffers. I'll buy 'em sonner or later. In order to realize if it works, how do I have to short the buffers?

  Here are some pics, I know I've built it really bad.  EDIT: (troubleshooting referred to the tangentsoft preliminaries) 1) using a 9V battery I measure 8.77V at V+ and V-. 4) no more the 15mV ground and the L/R output.

Hi, I've just built the pimeta v2 but it doesn't work. Some days ago the led didn't even light up, but after a bit of troublshooting I found out that I made some ridicoulus mistakes. Now the led lights up, but there's no sound, so I've checked the voltages at OPAG, OPALR and BUF pins relative to...

Quote: Hey k1n0n3, sorry for disturbing you in this thread. Check the mail box, please.  

Quote: I didn't know I could blew the chip just touching it with a pin of the tester!!! However, this way I'll check if there are pcb problems as you have mentioned.

Oh gosh, I would have to pay 10€ of shipping for 3€ of chips!!!! Do you think that now it is the only problecm? So if I replace the chips, the dac will work..

Damn it. So you think I've got to replace U1, U3, X1 and U2? Where can I find them?

U2 is correct. C5 = 5V, C1 = 4,9V
