My iFi Gold Bar! I got this from Japan from a dealer, I was incredibly lucky and managed to snag it at her cost! It truly is like the reviews say, it can replace some desktop setups!
I also own an iFi XDSD Gryphon, and for a while I was using it solely, through USB. Then I went back to the Gold Bar, and WOW! I prefer it more then the Gryphon, it has a fuller sound, everything sounds more forward, especially the low end.
The one thing I don’t like is that it doesn’t have a 0 noise floor. The power supply internals have been upgraded from the regular Go Bar, but still, listening using the super-sensitive Campfire Andromeda’s, there is a hiss in between songs and during very quiet passages. With the right USB cable though (DDHifi Nyx USB C) that shields the power and the data signals individually, I can eliminate the hiss in songs, and only hear it between songs if I listen for it.
Overall, one of the great loves of my life, makes digital bits into sweet, sweet angel’s tears!
So, although I have already messaged you this directly, I thought it best to add this message to the thread as it may benefit anyone else reading the comments to see:
I just checked your IEM’s matched with our GO bar on the headphone calculator tool on our website. This tool shows you if your headphones/IEMS (the list we’ve gathered has nearly all headphones options on there) match well with our DACs & Headphone amps (we have our full range uploaded on there too)
The Campfire Andromeda’s are quite sensitive IEMs with measurments showing 112.8 dB/mW.
Matched with our GO bar it shows that the volume would be too high if used together, regardless of if you chose the 4.4mm or 3.5 headphone output.
It also shows the volume being too high for the IEM’s even if you purchased one of our separate iEMatch cable adaptors too…
However, if you wanted to use an individual iEMatch (sold separately) in combination with the built in iEMatch on the GOLD bar then this could bring it down to a better noise floor for level you.
The GO bar is a very powerful little unit which is why we built in an iEMatch feature, but in this case I can see how it may be causing issues for you with those IEM’s specifically due to their sensitivity.
Maybe try another pair or IEM’s or headphones and this could potentially be a better pairing… Or if you are set on using this pairing of IEM’s and GO bar the you could have a look at doubling up your iEMatch in the signal path.
FYI iEMatch does not compromise signal quality, it just lowers the output.
I hope this helps to offer some sort of solution for your hissing!
Thanks,
Phil

I’m posting this part of my reply for others as well, since I don’t want others to think the Go Bar is unusable with sensitive headphones! It is usable, as my experience shows:
I have tried the IEMMatch feature, and it works well actually. if I set it to 3.5, it lowers it enough that I can still hear the hiss, but at the 4.4 setting I can only hear the hiss if I really listen for it. Unfortunately, it steals a little bit from the low end and bass, which is weird… It certainty doesn’t affect the quality of the sound at all, its just the Andromeda headphones, they are known to have a change in frequency response based on output impedance of the source. I’ve long heard this with my ears, and then I later saw a graph on Crinacle in their IEM frequency response database for Andromeda 2020’s (the model I have) where they measured with a standalone IEMMatch, and indeed there is more bass roll-off… These headphones are picky!
The Andromeda’s like more power than you would think… They sing when given some good juice! Also, the features like the filter settings and the X Bass and X Space are amazing to have. Buying the DDHifi TC09S Nyx USB C to C cable really did help too, so for others this is actually a solution. You will still hear a hiss between songs, but during music playing it will be absent, it is so low you won’t hear it in quiet passages. I would say that this is a great pairing because the quality of the Gold Bar is amazing, and the Go Bar isn’t supposed to be *that* far behind, and the Andromeda’s can take advantage of that quality. The soundstage is so vast, that when watching movies you can hear as though you are listening to a surround sound system. When listening to music the sounds come from behind you, in front of you, to your sides, all around! You can hear every last detail too, things I’ve never heard before in music I’ve been listening to all my life!
I have been planning on buying custom Campfire Supermoon’s sometime too, and those are quite insensitive planar IEMs (15.5 Ohms, 94 dB @ 1 kHz: 54 mVrms). The Gold Bar should be a decent pairing with those beasts, I hope!
I know that its almost impossible, or it may actually be impossible to design a headphone amplifier with both high output power and a low noise floor for super sensitive headphones! It really is one or the other, either you design an amplifier for sensitive headphones that has lower output power, or you design a powerful amp and it will have a higher noise floor. Personally, I bough the Gold Bar for its quality, which is unsurpassed by cheaper, less powerful amps with a lower noise floor, so I’m OK with the hiss, especially since I’ve found a way to make it better with a better USB cable! Also, I am thinking of buying an iDefender and trying an external power source for the DAC to give it clean power when its hooked into my laptop. that should also help!
