Do you have really, really sensitive hearing?
nah!
jk!
sorry to hear your having trouble there. I bought a used concero HP and no problems here. Hope you get it sorted out. maybe update the firmware would help?
Do you have really, really sensitive hearing?
Very audible? Strange. You may want to contact R-Labs. The HP does have periodic noise that seems like transformer noise, but it's ultra-faint (audible only with very sensitive IEMs when not playing any music), and I've never experienced it getting faster or slower in frequency. Do you have really, really sensitive hearing?
have you tried another pc or laptop to see if the problem is also present with a different source?
Periodic noise sounds like what I was trying to describe. I am running the Concero through a pair of FitEar Parterre. Initially I thought the issue to be one of sensitivity, so I tried two other pairs of earphones. But the noise was present on both. Could be what you described - periodic noise when no music is playing.
Here's the situation. I turn on the device, plug my earphones in, noise is present. No music playing. If I change the filter (magenta), it gets faster in frequency. It doesn't go back. As soon as I play a song, it disappears. But as soon as the piano key strikes, the noise comes back - and remains present for majority of the song. For example, playing 'clair de lune', I can hear the noise 'enveloping' most keys. I would think my ears are average?
I'm just wondering if this is normal.
Though 'Clair de Lune' is about as black space a piece as there comes, I can't imagine the noise coming through across notes.
I agree, because I don't hear the noise coming through on my MacBook's DAC. I also doubt it's a track issue, because the noise is present on other soft piano tracks as well. And I must note that it is never a single constant noise, if that makes sense. It changes depending on what is being played in the song. In any case, do let me know when you have tested it with a sensitive pair of IEMs. May be reassuring to hear the results. I appreciate the responses. Thanks.
The HP has lower residual noise (~3.5 uV) than the vast majority of USB DACs. I think you should definitely contact Resonessence to see what's going on, regardless of what I find.
You would need a USB cable running from the Concero to a wall adapter like those used to charge phones, to power the Concero while using it's coax input. I don't think the dx90 usb would power it but I can't say for sure. It may even attempt to recognize its usb as a data input and disable the coax input. I think there is a way to bypass that but I can't remember. You'd have to check the manuals on their website.

@project86, have you encountered this issue before?
Hey guys,
I recently purchased a Concero HP. Solid build quality and everything, but I'm experiencing weird - for lack of a better word - noise issues.
This isn't the usual background hiss that I get from my MacBook Air's DAC, which is quiet and constant, increasing or decreasing in volume when I change settings. What I'm hearing is noise that presents itself in intervals that become shorter (faster) when I change filters via the unit. It also doesn't become softer or louder with a volume change. And it doesn't go away when I mute the device through software.
The noise is very audible on softer tracks (e.g. classical piano) but disappears with most louder tracks.
I'm out of options. I will appreciate any advice.
Thanks.
Try unplugging the AC power cord from your MacBook.
Can't say that I've ever experienced anything like what he's describing.
Question for darknation - what are you playing when you hear this? Is it Tidal or some other streaming service? Or just FLAC files?
What manner of witchcraft is this?
I always assumed bass response was related to the amplifier and/or headphones.
I just replaced my desktop source with a Concero HD. I have never heard my Pico Power and Noble 4 combo hit this low with this much tonality and impact.

contrary to popular belief, source quality is the most important.
