    Venture Electronics RA2BFE Impressions and discussion.

    Was waiting for your impression vs PA10 as I have been planning to get RA2BFE. The PA10 will get more refined and open after or around 50 hours. It just becomes more effortless if that makes sense. So, keep an eye for that. But I am still planning to get the VE because the PA10's 4.4 input does...

    Introducing Shanling H2 - Budget Portable DAC/AMP with Built-in Player

    I have searched the internet and have pretty much come to the conclusion that the answer is no, but since there is no explicit mention of it, I am going to ask here. Does it have a microphone like the fiio btr series? Does the 3.5mm jack support a mic input? Since this is an entry level model...

    Tempotec V3 DAP - small, powerful, functional with Hiby OS

    Oh, that's alright. The takeaway is that the LO voltage is not too low, which is a positive thing to me.

    Tempotec V3 DAP - small, powerful, functional with Hiby OS

    Hi, can you test it with the 4.4mm line out mode too? I am considering getting v3 just to feed my portable external amp using line out. It fills a lot of my requirements - 4.4mm LO, dual AKM, non Android, great battery life while being compact. I don't care about the inbuilt amplification and on...

    I have used Gizaudio Binary Chopin (12ohm/122db) via RU7 4.4mm LO -> PA10 4.4mm. It was fine, no issues. The volume pot is pretty linear.

    Cayin RU7: 1-Bit Resistor Network Dongle DAC /Amp

    That looks like grounding issue. Make sure that your 4.4mm cable has proper grounding. If you are using a 2.5mm cable with a 4.4mm adapter, it may also cause grounding issue since 2.5mm doesn't have a grounding.

    Do make sure that you are actually triggering the high impedance mode of the LG when you connect the PA10. This will give 2vrms to PA10. Input voltage do matter. Out of curiosity, I have fed non-american apple usb-c to 3.5mm dac to PA10 and it was pretty weak, even in high gain of PA10.

    Samsung's 15w charger which would be available globally I think.

    Final Audio Design Impressions and Discussion Thread

    Hi, Has anyone tried and found out some tips for ze3000 that doesn't change the sound but just increase the isolation. I tried normal E-type tips. While the isolation did improve, the sound did become a little harsher to my ears. I wouldn't even mind if the sound become a little bit smoother but...
