I only know three of those artists, lol. I don't know if you have the track, and I don't LIKE the track, but Kanye West's "Gold Digger" is my go-to test for distortion (clipping?) and generally the mid-bass falling apart or holding together. With bass boost "ON," there is a little body and fullness added to the bottom end, but the sound holds together smoothly with ease. I pulled up Eminem's "Lose Yourself," just for you, though I like this song much more than the previous one, and with the boost, the bass drum that kicks in at 0:52 really does kick pretty well, yet it's easy to hear Marson's lyrics without any verbage close to "picking them out." The song "Without Me" already seems to have a good bit of bass on the flat mode, turning "on" bass boost brings that bass forward a bit. This is all with Q701 headphones and Mont Blanc set on 0 dB gain. I used to have V-MODA LP's, but there's plenty of bass in this current setup for me.
I took some more pictures for size comparison. People that use money clips instead of wallets need-not apply, but if you've ever had your phone and wallet in the same pocket – Hey that gives me an idea... Yup, my wallet is just as thick as Mont Blanc – then the amp + PMP ought to feel about the same. Here's the Mont Blanc next to my mom's phone & my iPod to show scale:
Top is Mont Blanc
The Mont Blanc is clearly better constructed. Solid piece of aluminum next to the creaky plastic phone that seems like the pieces are more loosely put together by comparison, while the FiiO only has 2 hairline seams around the volume pot/input/output side and the opposite (bottom?) side with only 2screws visible down there. The majority of the enclosure is one piece of aluminum that looks like a tube, with no seams longwise along the body, so it feels solid like the new iPhone 5 (or a unibody MacBook Pro, I guess).
I don't think there is a lightning LOD yet, but if I can beg my gf to share her white iPhone 5 with me for a minute (or she's sleeping), I'll let you guys know my impressions double-amped connecting the Mont Blanc to the iPhone's headphone jack, compared to the L11 LOD for my iPod video (5th gen). I can probably write my review of the Mont Blanc this week, I'll probably pull impressions I've shared from this thread and add anything i think of like comparing to the iPod headphone out. A "crazy comparison" to my desktop amps & the E5 will come in my journal thread, I call it "crazy" because they're all for different purposes so it will be a fun opinion review rather than a practical, objective review.
