    The Qudelix-5K thread

    This is a nice article (although an advertisement for their crossfeed circuit somewhat...). Oops, forgot the link: https://www.headphones.com/pages/fixing-headphones-using-electronics

    Fantastic! A small amount of crossfeed goes a long way and this has now made an amazing device even better.

    RME ADI-2 DAC Thread

    It will remain constant and I believe it is always be transmitting at 192kHz. Anything less gets upsampled.

    Hmm, not sure. This is what I see: . Maybe a MacOS version issue?

    RME ADI-2 DAC Thread

    On a mac you need to run "Audio MIDI setup" and tell the computer what rate to use for the RME. It will not set it automatically. I leave mine at 192kHz.

    Hifiman Sundara (HE400i upgraded, around $500)

    You can probably do without the bass low shelf or reduce the gain a lot. I put it there based on playing with a frequency generator, but it rarely makes a real difference in terms of music.

    I guess so, except I’ve had Grados last me more than 10 years of constant use... I think that is longer than the lifespan of most consumer electronics.

    I of course instantly adjusted the headband so that I have very little pressure on my ears. Why don't other headphone manufacturers make bands that can be bent to a customer's liking? It seems so easy and makes all the Grados very comfortable to wear once you have them bent to your liking.

    Received a pair of the hemp today. Amazing frequency response without any EQ. I am not usually a fan of the flat pads but will keep listening. Definitely a little different than my other Grados but a welcome addition :)

    Huh? The DAC takes in the digital input (0s and 1s). This study shows that the digital signal coming in doesn't depend on the cable. You don't need blind tests etc, there is provably no difference in the digital string of bits coming into the DAC. If you really thought USB cables had errors like...

    This is misleading and does not effect the DA process or the final output analog signal. While technically correct, indeed there are thresholds used to separate 0/1, the process is synced to a clock and the signal is never read out at anything like 0.5V.

    The Qudelix-5K thread

    Re. raw sound quality, probably not. But, you get 10-band parametric EQ which can definitely improve sound quality unless you love your IEMs un-eq'd. Additional things are balanced input (more power, but unlikely to matter unless you have uncommonly inefficient IEMs), and being untethered from...

    I also put the cables over my ears. I find this greatly reduces both any effect tugging on the cable has on the seal in the ear and microphonic effects from the cable moving around.

    ThieAudio Legacy Series IEMs

    I bought the Legacy 4's from a fellow head-fier and have been enjoying them a lot for the past few days. For those interested, here are my PEQ settings which bring the FR to the Harmon 2019 v2 in-ear target curve. It's not perfect to my ears but better than stock and very good. Filter 1: ON...

    How to audition by mail during COVID

    Hi all. Does anyone have suggestions for outlets that allow auditioning via mail during COVID (I'm in the US, NJ)? I know I can buy new and return in new condition to a number of good outlets but feel a bit bad doing this. Advice?
