Well, the G6 isn't a powerful amp, certainly not one to make HD600 shine. Just because it plays loud doesn't mean the headroom is there. The HD600 is what, 300ohm? I think you'd do better with a desktop amp attached to the G6 for it. Though I still see expect miracles.
The HD600 isn't a "full" sounding headphone to begin with.
As an “amp” the G6 does not sound great compared to the MixAmp 2019
Ok so this deserves more context.
Last night I purchased a G6 and began testing it against my Mixamp 2019 and Modius/Asgard 3 DAC/Amp combo
All 3 were connected to my PS4 through TOSlink. The headphones I used were the HD600, PC38X, T60RP Argons, Sundara, and AKG K702.
I played Overwatch in a workshop mode with plenty of characters and sound queues and even ran Resident Evil for a bit.
Switching back and forth it was pretty clear that amp performance went to the Asgard 3, then MixAmp 2019, and lastly the G6. Which surprised me because of the rave reviews found all over the internet for the G6 and less-than-stellar reviews for the MixAmp. I expected the G6 to beat it handily.
But that was yesterday, and this testing was done with a flat eq curve and NO Dolby 5.1.
Today on the other hand I did more testing but with VSS enabled. Now, it was pretty clear that the G6’s SBX was noticeably better than the MixAmp’s Dolby Headphone. I’ve been using it for the better part of the day and sound queues for flanking enemies are much more distinct, making it easier to tell if they’re an immediate threat or not.
In conclusion, the G6 is worthwhile only while using SBX. When compared to the MixAmp without VSS, it didn’t hold its own. The MixAmp 2019 sounded fuller (not nearly as full as the Asgard 3). But enough that when connected to the MixAmp, my headphones sounded like themselves. While when connected to the G6 they sounded more like Hasbro products.
What I’m getting at is I feel it’s dishonest to say the G6 is the best gaming dac/amp when this is only true when SBX is enabled.
I only say this because the G6 has gotten rave reviews not only in this forum, but also from prominent YouTube reviewers, and in another forum that I won’t mention here.
If you play single player games, are a casual player, or like to listen to music/Spotify while gaming, putting “pure competitive” sound to the side, there are much better options like the MixAmp or a dedicated DAC/Amp combo.
