Unless you're looking at driving low impedance/highly efficient dynamic (non-ortho) headphones. smile.gif Too much noise floor for my tastes. The GS-1 and GS-X though are DEAD silent with even uber sensitive IEMs.

Noise aside, the designs are radically different.

Agreed. But both are great options!

The GS-X on on the lowest gain is dead quiet with IEM.  The GS-1 is very good... my goto amp for my HD800s, but it is not dead quiet with IEM.  Somewhere between 1/4 and 1/2  turn of the volume knob on the GS-1 and I can make out noise with my IEMs.  But I guess this is a technical detail rather than practical.  A 1/4 turn and my ears would be hurting with most tracks.

The unity gain (Low) on the GS-X is a brilliant idea. Some older GS-1s didn't have it set to unity, so that might explain the issues with your GS-1?

Huh confused_face_2.gif

 

The B22 is great with my At's and Denons.

I bet it is...just the noise floor isn't as ideal IME. Also depends on your gain setting.

IME = in my experience smile.gif

 

(Sorry, long week, so I'm taking short cuts).

Yes, the gain of 1 on the GS-X makes it extremely versatile.  I do have a one of the older GS-1 and it's low certainly has more gain than the low on the GS-X.  I have assumed that the low gain on my GS-1 was 3 since that is what the information sheet about the gs-1 at headamp.com says was the standard.

I do hear some hum with my GS-X on medium gain, so it could be the gain of 3? Before I bought my GS-X, I had Justin's second last GS-1 and with unity gain for low, it too was dead silent with IEMs.

No problemo.

since the input signals to the pot and from pot to board represents a high impedance circuit, it's going to be much more prone to picking up random noise.  having those jacks, pot, and signal routing directly mounted on the PCB will do much for noise attenuation.  the B22 boards themselves are dead quiet with my 103dB HPs and gain of 8x despite being a fairly complex design with discrete components - it's the wiring to and from the pot and layout that can introduce noise.

For the record, I have never heard a B22 from SolderworksAudio. smile.gif
