Set LH as default sound from Windows CP (or from volume icon - right click).

 

Right click speaker icon and choose you're volume slider

Do you mean going into the speaker properties > levels tab > inputting volume #s manually? (i.e. 23)

Nope, set Geek Out as the Default Sound device and use the system volume / speaker icon slider as the way to adjust your volume.

Haha yea thats what I do. Except it gets excessively loud even with the volume slider under 10%. So I have to keep the volume under 10% at all times and that limits my flexibility with volume control.

As I mentioned earlier, the Windows volume slider affects only the analogue volume in the LH Control Panel. If the volume is too loud with < 10% analogue volume, I'd suggest manually controlling the master volume slider in the LH Control Panel.

does this potentially produce not bit-perfect output from the DAC to the amp?

Thanks for your help! I will try it out.

From what I understand, the computer always outputs a bit-perfect signal into the DAC, but at less than 100% volume level, the DAC does internal processing to do the digital volume control. The ESS Sabre 9018K2M uses 32-bit signal processing for this volume control, and is how 1-bit DSD signals can still have digital volume control as well (usually it would be impossible to have digital volume control with a 1-bit signal).

So the short answer is yes, the signal is bit-perfect,on the computer-DAC connection, no it's not bit-perfect per se within the DAC itself if what I stated is true. Regardless of whether or not it's bit perfect, the real question is, can you hear it? ; )

hah good point. Thanks for the explaination.

My greatest frustration with the Geek Out 100 IEM is that the volume control sucks. on my surface pro 3, 8 is a bit too low and 10 is a bit too high. Getting to 9 is hard because the volume rocker does increments of 2. Lowering the gain in the control panel solved this. Thanks

3D Printed Chassis

Utilizing the latest 3D printing technology available, Geek Out V2’s chassis allowed us the ability to radically optimize the form factor and design aspects that would have otherwise been impossible using traditional manufacturing methods. Furthermore, 3D printing allowed us the ability to incorporate built in heat sinks and ventilation chambers that reduce the radiant heat dissipated by Geek Out V2’s Class A amplifier as well as being able to incorporate non-parallel walls in the design structure to reduce internal vibration.

...

Digital Control Analog Gain Settings

Geek Out V2 features multiple analog gain settings which solves the problem of deciding which output level will work best for your ever expanding headphone collection. With selectable gain settings of 1000mW, 450mW & 100mW, Geek Out V2 pairs perfectly with those monstrous power hungry cans or your uber sensitive IEM’s.


Advanced 64 Bit Volume Control

In the past, attempts to engineer digital volume attenuation has been panned by audiophiles due to its very obvious “digital-ness.” Analog volume control has been preferred, though it also presents a problem because of the noise that it generates. We’ve taken a different approach to volume control with our advanced 64 bit attenuation circuit, which uses an ultra-high resolution, zero noise, bit perfect mechanism.

Geek Out V2’s volume attenuation circuit replaces the computer’s volume calculations with its own, ensuring that your music remains bit perfect all the way through the conversion process. This way, it ensures that no information is lost before Geek Out V2 gets the data.

...

Frequency Response: 2 Hz - 55 kHz (-0.1 dB)
Maximum Power Output: User switchable. 1000 mW @ 16 ohms. 100mW @ 16 ohms
Maximum Output Voltage: 4.0 Vrms in high gain setting.

Total Harmonic Distortion (THD+N): <0.01%
Signal to Noise Ratio (SNR): >105 dB unweighted. > 108 A-weighted.

Input: USB 2.0 (Asyncronous)
Outputs: Dual 3.5mm analog stereo (one single-ended, one TRRS balanced)
Output Impedance: 0.47 ohms
Output Stage OpAmp: Texas Instruments TPA6120A2
Amplifier Output Bias: Class A

Digital to Analog Converter IC: ESS SABRE9018AQ2M
USB Controller: XMOS XS1-SU01A-FB96

PCM Sample Rates Supported: 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz, 352.8 kHz, 384 kHz

I considered trying the GO V2 with the Cavalli LC but I think I'll be holding off for the time being.

I'm looking into this too. It seems a little crazy to pair two unknowns though...

Well coming from your GO SE...... XD

There's a GO V2 SE. ;)

 

Seriously, if my GO SE had both a single ended and a balanced output I think it'd be my perfect portable DAC. I have balanced headphones and balanced amps that could be fed from a balanced GO. And if I understand it correctly the GO V2 SE will be less expensive than the GO SE; that's a win-win for people who missed out the first time around.
