I use a Beresford 7510 MarkV and an RSA Hornet (original non-M version), with both Shure E4c and Beyer DT880 headphones. The Hornet absolutely slays the builtin headphone amp in the Beresford when using the higher impedance (and much more capable) DT880's. The Hornet is better in every way. Better attack, better bass, less congestion, louder clean volumes, ...
I've not had experience with many other headphone amps, but I'd call the built-in Beresford headphone amp decent at best. The DAC is quite good, it deserves to play through a good amp!
