    Audio-GD Master 9

    I have not heard the master 9 so I can’t compare it to the HE-9 or say if there is much of a difference.

    Audio-GD Master 9

    I got the Massdrop Cavalli Liquid Carbon X and compared it to my HE-9. The HE-9 was the better amp by quite a bit. The bass on the LCX was pretty loose compared to the HE-9. The HE-9 also had a lot more detail. Granted this is probably not much of a surprise given the cost difference between...

    Audio-GD Master 9

    I had the NFB 28.38 which is a DAC/amp but similar to the NFB-1. I sold it and purchased an HE-9 which is similar to the Master 9. The resolution is better in the HE-9 and the soundstage is larger. I think they have a similar house sound if you will which aligns with my preferences. Those...

    Audio-gd NFB-28

    I’ve sold my NFB28.38 and moved up to the Audio-GD HE-9 for my amp. I don’t recall the details other than I was able to follow the labeling on the NFB 28.38 user manual site located here: More specifically I attached the...

    Audio-GD Master 9

    Agree completely on using headphones balanced connected via the XLR output to not waste 1/2 the amp. Regarding dacs connected to the HE-9, my feeling is there isn’t much in single ended vs balanced as they both use all of the amp. It comes down more to DAC vs DAC. Granted the volume will be...

    Audio-GD Master 9

    My personal experience with using my HE-9 with the Chord Qutest which is singled ended has been extremely positive. Since the HE-9 and Master 9 have a phase splitter for single ended inputs, I’m not sure balanced vs single ended matters as much as getting a quality DAC with a presentation you...

    Massdrop x Airist Audio R-2R DAC: A Discrete Resistor Ladder DAC For $350

    You could use a pre-amp such as the Schiit Saga in the non-tube mode or a 2nd amp with pre-amp function to match the levels between the 2 DACs.

    Sonarworks Headphone Calibration software

    Following up on this, I'm wondering if the amp setup Sonarworks uses to create the HP profiles is not powerful enough to get accurate bass from planar magnetic HPs. Purely speculation on my part that that is the cause of the problem. Hopefully someone with Sonarworks will look into it.

    Sonarworks Headphone Calibration software

    I really enjoy the Sonarworks Reference 4 profiles for my supported headphones. I just got a pair of Hifiman HE400i's to use with Sonarworks Reference 4. The detault HD400i calibration sound has too much bass. The frequency response shown on the chart shows bass roll off that is much larger...

    Gilmore Lite Amp Owners Unite!

    The discussion about the new Gilmore Lite Mk 2 power supply has me wondering a few things. The stock power supply brick is a linear power supply. Will the new power supply just be a similar power supply in a form factor / chassis that matches the amp? Or is the intent that it will be an...
