I'll get myself a X3 mainly for the built-in amp.
My SM64 (96 Ohm) neeeeed the power!
.........I don't think NEED is a necessary word there.
Most earphones are really sensitive, regardless of their resistance.
Apple In-ear 2013: 0.02 mW to reach 90 dB SPL - 49 Ω
Astrotec AM90: 0.01 mW to reach 90 dB SPL - 57 Ω
Audeo PFE 232: 0.09 mW to reach 90 dB SPL - 46 Ω
Creative Aurvana In Ear 3: 0.00 mW to reach 90 dB SPL - 86 Ω
Grado GR8: 0.01 mW to reach 90 dB SPL - 99 Ω
HiFiMAN RE-262: 0.01 mW to reach 90 dB SPL - 149 Ω
Even if your earphone needed 0.1 mW to reach 90 dB SPL (which is what portable headphones typically need, if even), you would only need 12.8 mW of power to reach 111 dB SPL, and that's plenty loud. Most amplifiers can supply more power than that at 100 Ω.
