Yeah, since there's a limited set number of steps on the GO, the 1000 won't give you much range of use with sensitive headphones. I don't have mine yet, but I would think only a couple before it gets too loud. And since the GO resets each time the system volume changes, you'll blast your ears.
I have no first hand experience just yet, but I will in the next couple of weeks. But if I remember correctly from the reports other owners have given, that it only resets based on system volume changes. Individual applications are independent and shouldn't have an effect on the GO's settings. Again, that's what I understand but can't confirm just yet.
Thanks, I received my unit today and that is what I am experiencing. The software volume control in JRMC19 is not having any sort of reset to maximum effect on the GO 1000, and I can move each one independently with no governing effect on the other.
I haven't tried any kind of system volume changes because that's not how I use JRMC19 anyway, and also because I don't want to blow up my ears or headphones!
Early impressions are quite favorable and impressive, I use the Resonessence Labs Herus here at work and so far the two units are sounding similar, with the GO 1000 possibly a little fuller in the bass/mid bass (without bloat) and also more dynamic overall. The dynamic thing seems to be a function of an even quieter background than I get with the Herus, so not louder so much as revealing low level detail on quieter passages, and greater overall punch on peak crescendo moments too.
This is a good thing as I am a big fan of the Herus despite what some others may think of it, but I also don't have any super difficult to drive cans either.
The Herus is a great sounding unit with the various headphones I own, so the GO 1000 more than holding it's own despite a zero break-in period is quite impressive.
It's hard to tell specific differences in my work place arrangement because getting the levels matched is difficult and inexact here in my desktop set-up, and also due to there being two different volume controls available when using the GO 1000, vs. just the JRMC volume control available when using the Herus.
Which brings up a question: which is the more favorable volume trim arrangement? JRMC set to full and then attenuation using the GO 1000 buttons? This seems to offer a finer gradation if I'm not mistaken, as if each GO 1000 button press is less than the 1 dB you get using JRMC19's slider.
Or, is the GO 1000 set to full volume and all attenuation occurring in the JRMC19 software domain technically better in any way?
I just don't know, and I may never as the GO 1000 is actually slated for line level DAC duty in my bedroom system, a Mac mini running Audirvana+. The GO 1000 will connect to the line level input of a Sugden Headmaster preamp, replacing a perfectly good sounding Musical Fidelity V-DAC II due to it's 24/96 PCM and no DSD limitations.
