    The unit I got is with stock opa H20 has is warmer and more slam then 789. Basic sound quality is close. But it don't fit with Sony headphones.Make it muddy. And the step volume gain setting at BAL out. Too much power for Z1R and iems. It plays too loud at the first tick of the step...

    Massdrop x THX AAA™ 789 Linear Amplifier - Impressions Thread

    I am using Z1R,A2000Z,Z7,TH-X00,SRH-1840. They sound weird on my 789. The mid-range (vocal) image is excessively wide and big.I can feel a huge mouth in a close range. In some tracks it covered over 80 degrees field of view. This sound signature is special. And none review I seen mention it...

    Schiit Jotunheim Review / Preview - Head-Fi TV

    I see. I totally agree with what u wrote.   Going from balanced to SE is a big downgrade to me.So i was confused why u do that. Now I know  it's sound signature cause.   Jot Amp has no strong sound signature.The sound can be changed  by changing DAC. But Jot w/ DAC has fixed sound...

    Schiit Jotunheim Review / Preview - Head-Fi TV

    I was  wondering you use 1/4" trs or XLR when you comparing jot's internal dac and mojo?   I tried both when I comparing Grace M9xx(as dac) 、Pioneer XDP-300R(as single-end and balanced dac) and jot internal dac.     SE phone output        M9xx>300R(both SE and BA) >>>> jot DAC  ...

    Schiit Jotunheim Review / Preview - Head-Fi TV

    I think this is the case.   I tried wyrd at local store with my own Jotunheim /w DAC for 2 hours.I can't tell the difference. But also tried DragonFly Red. DFR gets a lot improvement from wyrd.   I tried these with Surface pro 3 which has poor usb power (can't power a DVD writer) and...

    Schiit Jotunheim Review / Preview - Head-Fi TV

      What confused me is the heat is really different whether pc connected or not.(muted in windows and left overnight compared with pc shutdown) But when I asked Schiit about this they said that is power consumption is always the same once Jotunheim powered.

    No really issue. But if DAC connected to working PC,it never goes to idle. And jotunteim gets really hot.

    New Dragonfly Black and Red Discussion

    I am using DFR+Q701 DFR does a lot better than DF V1.5 with Q701 DFR offers more detail and bigger stage.  And DFR beats my old device Fiio X3 In both sound and convenience   Unless your phone is a Android phone like mine.(suffer volume issue) I think go  DFR is good choice.
