Pioneer XPA-700 Portable Headphone Amp & DAC Review

[Martin]

Thanks, so they form a cable guide when you strap it to a phone?

Other than higher output and slightly higher power, this performs worse than an Apple headphone adapter and many phones, and for that you carry around this chunk of tech with sharp pocket-damaging corners. I'd like to say that at least it saves usage of your phone battery, but power drain using IEMs is minimal anyway.

...but the circuit topologies have vastly improved.

But have they actually? I don't think they reinvented the I/V converter stage or differential amplifiers?
