if your source device has a noisy USB ground, e.g. Gaming PC with high power graphics card(s), then fully balanced DAC + HP Amp + cans may have a lower audible noise floor vs single-ended that are AC powered using 3-pin grounded (e.g. IEC connector) plugs. Note: do not remove / defeat ground pins on AC cords (may cause safety hazard)
Awesome, so it seems like I won't really benefit from having fully balanced since I'm not running into any noise issues, just something I was curious about.
Another forum has someone saying it's an improvement over the modi 3 soundwise...so I'll see what the general consensus is in the coming week
