Ok, use LH labs 2G usb/Regen/Geek out special Edition. It looked like disconnecting and reconnecting the GO from the Regen was what solved it. I connect it directly, no cable.

Great that you have it resolved.  One of the connections (surface to surface) was probably not tight or micro-arcing causing the distortion.

Hi,
 
I have a geek out 1000. I have a problem with it. How to set the correct Tcm filter?? I found that the online support manual says:
 
The top 2 LEDs (out of the 3 on top) will light up when TCM is engaged
https://support.lhlabs.com/support/solutions/articles/5000564236-geek-out-owner-s-manual-
 
 
and the pdf manual and the most common idea says:
 
To turn on TCM, click on the convex side button. You’ll know it’s on when you see three LED’s illuminated at the same time.

What is the real button/led response?
 
Thanks a lot!

Well, if you need TCM just plug it in and don't press any of the buttons. It is my understanding that the Geek Out doesn't store which mode to use when you plug it in and it defaults to TCM.

Open the cover of my new windows 10 laptop with the headphones plugged into the geekout and it came on at full blast. Scary and I hope I didn't suffer any long term damage.

This seems like the kind of oversight by LH that could elicit a lawsuit.

In fact, 24 hours later, they still hurt.

This sort of thing has happened enough that my GO1000 went in the drawer and has never come back out.  What a really poor software design.  You know, at least they could default to -∞ for volume rather than -0.

never had a problem with that issue with the latest firmware

I really like the Geek Out Special Edition, but the volume issue was also crazy making, generally just use it with an external amp (which makes it less portable, of course, but I use it with my PC all the time).

Same here. Even with updated FW, the volume issue on my GO450 still reared its ugly head on occasion. Too scared to use it or give it away so it's basically trash.

Thanks namaiki,
 
But tcm is convex button / 3 leds or concave/ 2 leds ?? I say this because i prefer convex filter mode and i don't know if is one or the another one!
 
Thanks a lot

and I noticed Gavin Fish left Light Harmonic.
 
Sorry guys.
 
I couldn't know these guys would pull this BS!!

 

[doctorjazz]

I pretty much use it line out, into an amp, avoid the volume problems, DAC is very good sounding (have the GO Special Edition). But, yes, the volume issue is bad.

Hello... May I check with someone who has GO1000 if below is normal?
 
I just got GO1000 (red) with v1.5 firmware update and noticed below weirdness.
 
1) 0.47ohm and 47ohm output power. 
I hear slightly louder on 0.47 ohm than 47 ohm connected with headphone. The difference is not huge but definitely 0.47 ohm connected with headphone is louder a bit. Isn't it supposed to be opposite?
 
2) Amp Output Power
With GO1000, the volume output is marginally higher (about 10~15%) comparing without. My source is primarily Macbook Air 2015. Isn't GO1000 1 watt class A amp and it should have plenty of power to drive and noticeable difference on output power comparing without amp? I had to go up 70% of volume with ER4S to match 80~85% volume without amp.
 
Thank you....

1. The 0.47 will always be louder because it has less resistance
2. The ER4S has very high impedance, which means it is hard to drive. The GO 1000 is rated for 1000mW into 16 ohms, which is a bit cheeky as most power ratings are into 32 ohms. I'm not surprised that it took 70%. The MEE Pinnacle P1, has 50 ohm resistance and takes about 50% volume with my Geek Outs.
 
Enjoy your GO 1000, it's a good little unit.

Thank you so much for your detailed response. I was surprised because GO1000 is class A full 1W amp so it should be enough to drive even 600ohm headphones such as DT990. I think that this unit may struggle to drive headphone with 300ohm or more... 
 
Besides, I like the sound out of this unit. It is cleaner and slightly warmer than stock Macbook air that pair with my MSR7.

I have an HD600 and it sings with the GO1000

What volume level out of 100 do you go to with HD600 (300ohm)? I just tested with Yuin G1 which is 150ohm and I had to go to 78% of volume which is not too loud but loud enough and listen comfortably.
