interesting on the amps I have owned with balanced out the power rating was always double or therabout

is the hpa4 double the power in balanced mode?

The 6W (into 16 ohms) I believe is run in balanced outputs (inputs don't matter with this balanced amp).

I go fully balanced from my DAVE to WA33 to TCs. Compared to single ended, balanced sounds better and has more authority in the bass. I’ve tried SE with the TCs, and you can definitely hear a difference when going fully balanced. However, Woo Audio did design the WA33 to be fully balanced though, to be fair.

according to this review of the HPA4. it says both SE and balanced have the same power.

https://www.headphone.guru/the-benchmark-hpa4-headphone-amplifier-the-leader-in-transparency/

'Both outputs deliver the full performance and power of the HPA4! So there is no need to run out and purchase a balanced cable for your specific headphones! '

Pfft...what does that guy know? :p Forgot that one...thanks for the reminder. Damn middle aged memory. I mixed this up with the GS-X mini (which I also reviewed and currently own) and it requires balanced outputs but not inputs (the opposite to the HPA4). FWIW, both are brilliant and driving the Phi TC. :)

I think there is a confusing subject , on balance connection to a pre-amp so pre out, and balanced from a headphone socket such as a 4 pin out
A headset wired as balanced is very different. Balanced for pre out is designed to be able to do longer cable runs.

my client produced this :)
Woah, really? Recently ran into it. One of my favorites! It has a unique BGM to its genre. Would be awesome to talk more here or, if many messages, through PM. :)

Just picked the Phi TC's up recently and definitely, they do almost everything right and are phenomenal. My only real gripe is the bass distortion on select* songs (typically those that are more bass heavy) while listening at higher volumes. Most songs are absolutely fine, but some are just unlistenable at higher volumes.

I was thinking maybe the TC's could use more power than the GSX Mini can provide, but it honestly seems like they drive them pretty well. And combing through this thread it seems like it may just be an issue across the board regardless of amp? Can anyone help to confirm? Is there anything that can help outside of turning them down or EQ'ing?

what specific songs that you found produce "distortion"?
