I will edit this post with what I found of my listening time, BUT I hate to spoil it before I start (But we knew this already really), Bojamijams hit the nail on the head.
It drove my IE7's (without amp) to average sound quality - I could tell these are nice musical earphones but the loudness was missing completely. (YES REALLY, Full blast and i didnt think for a second that: wait.... these are becoming a bit too loud). I know quite a statement since IE7's are fairly easy to drive.
I USED STOCK MP3 Player, NO EQ
Track 1: Inna - Amazing:
Sennheiser IE7: Wide soundstage, but a thin sound. Lows are OK, highs are average.
USING THE 5.1 Sound proccessing function - Hopeless. Muddy, too bassy. Dont ever use it. lol
PFE 122: Good soundstage but slightly 2D. Flat, thin, lifeless sound. highs and clarity are very good but sounds like a cheap MP3 player with bundled earphones. Lifeless, not musical.
USING 5.1 amp/boost option - Muddy across the entire spectrum, busy sound.., no definition AGAIN. Artificial bass boost sounds like its tearing large woofers. Kind of like a 16 Year old who bought his first 10 inch sub from halfords and is wearing it in on full blast (Sounds like sh%^$%^$t! lol)
Track 2: The Roots - How I Got Over (Live) NOTE: From The Album Late Night With The Roots
IE7: Good imaging, very wide sounstage. Very musical sound but finer details and highs are reccessed. These can be EQ'd using powerAmp.
PFE122: Nice highs, great clarity but no weight to the music. Soundstage is good and quite wide. Also has a surprisingly 3D sound but lacks weight and punch. Cymbals sound good and crisp. Listen to this on full volume to be enjoyable and energetic sound.
NOTE: I stopped using the 5.1 upscale as its useless
Track 3: Ludacris - I Do It For Hip Hop Last of a Dying Breed (Live) NOTE: From The Album Late Night With The Roots
Link for The Roots Album/Songs - See bottom of the page - http://www.refinedhype.com/hyped/entry/late-night-w-the-roots-mixtape-download/ - STREAM THE TRACK
IE7: Full engaging sound. The lower mids are a bit muddy and abit too much going on at times. Full volume is not enough to stay loud. EQ a bit of highs and it sounds more forward and agressive but without EQ - sounds good but largely due to phones used.
SENNHEISER IE7 USING FiiO E7: Separation is MUCH better, highs are well defined especially the cymbals. Cymbals have great definition to them. You can imagine ?UestLove smashing them and see the cymbals crashing and rattling. VERY VERY GOOD WITH E7.
PFE122 With Stock Tips: Only good at max volume, SGS2 amp is not powerful enough to drive these adequately, good sound but need an amp to replace or find the weight in music.
PFE122 WITH COMPLY TIPS , NO E7: better weight with comply's but highs are better without them. They are a bit too tamed/reccessed with comply's
PFE122 With STOCK tips and FiiO E7: some warmth restored. Musicality is added particularly in the mids. Sweet mids now, weight and scale is added too the Low mids and low end. Definite improvement.
SGS2 has not got the power to drive headphones to their best even with headphones that dont really need an amp to do well and enjoy your music.
IE7's musical nature helps SGS2 and with an amplifier i'd say YES, great sounding setup. SGS2 + FiiO E7 is worth it! But for the more analytical headphone e.g. PFE122's you need an AMP/EQ a lot or you're losing out on enjoying the phones as they are no where near as good as they should be.
