    Luxury & Precision (LP) Portable USB DAC/AMP W1 and W2 (The new W2-131 Version is Available, Related Info on Post #1)

    Andrew (Musicteck) wrote me this: As far as we tested, there is no issues with W1 since it only draws 90mA, but W2 draws 110-120mA and iPhone has a limitation of 100mA to support external devices. So, when using W2 with iPhone 11 or 12 and W2 volume is over 70, it draws more current than iPhone...

    Updated on my girlfrieds NTB W10. Why doesn't LP do an update tool for Mac? Is it that complicated? 🤔

    continuation of my posts #823 (first), #871 (last) This is because the iPhone's USB output current is strictly limited, about 100mA, so if the iPhone's output is unlimited, there will be no problem. Best regards, L&P Sales Director ZhangTao

    What W2 settings do you use to listen to EDM (if any of you are listening) with your IEMs? For my ears sounds good EQ: normal, FLT: LL fast, Tune: 02

    Thanks a lot for your info and test, it calmed me a little bit, we'll see what the guy from L&P says, but as it seems iPhone power supply restriction is the true reason...

    I have only S1 to compare with W2, but in addition to the stuttering issue is W2 in all way better than S1 (I miss only MQA, master tracks on Tidal are with S1 comparable or even better). W2 little bit bigger stage, blacker background (totally no hiss, first time), better separation with my...

    Looks like it... My Solaris 2020 Impedance is 15.5 Ohms @ 1kHz. But even with the stock W2 white cable and my iPhone it doesn't work as it should.

    Guys, my W2 arrived an hour ago, hooray. First of all, the good news: no or negligible EMI at all (iPhone 12 Pro, wifi, cellular network), so twice hooray, I'm excited (with my iPhone, S1 and balanced 4.4 Penon cable it's a huge problem), buuuut .... Second, the bad news: at higher volumes...

    Lotoo PAW S1 - Designed for HIFI on the go with Lotoo PAW quality and the first USB DAC-AMP with dual 3.5mm & 4.4mm output

    I am using one of the most sensitive IEMs out there which picks up hissing with every source. Then, I switched from Campfire stock cable which has plastic plug/connector housing to another cable with metal plug/connector housing to have a conductive antenna connecting S1 through its 4.4 BAL jack...
