Powering with a Fiio E17, no issues there I suspect.
I do have a few mods I need to reverse to A/B again (HM5 pads, some damping material in the cups), its the trebble, something around 4k that gets me, I want to turn it up to hear the mids, but the 4k (not confirmed freq) then becomes fatiguing.
I recabled the uptowns today, bit of a pain, ended up replacing the whole cable with a spare disconnectable cable from the HM5's. There seems to be more bass extension now and no imbalance issues (even at a few days old, I kept feeling like I wanted to adjust the slider to make sure there wasn't imbalance. Couldn't get into the section where the cup pivots on the headband, so added 2 holes through the back of the cups, added small grommets, a few layers of heatshink on the cable coming through the grommets and all done. Not hard cans to work on other than having to add a new cable.
Due to the shape of the cups, the cable sticks out at 30 degrees rather than straight down. The cups don't appear to be deep enough to support making a removable cable without having the socket stand out from the cup.
Love these cans, very happy @ $60.
- Edit -
The bass extension is definitely improved with the recable. I'm a mild basshead (thus why I went for the 770 80's), I found the sound of the uptowns engaging enough without them going low, but I can notice more feel to the bass where previously there was just the good bass punch.
Clint Eastwood by Gorillaz: Not head rattling, but the punch feels awesome, extension is there. Getting all the way down, just not as much bass boost below 30hz as I would put in my dream cups. Still U / V shaped. To add some context, I thought the 770's didn't have enough extension (what some call sub-bass), I'll A/B again, but these have more power down low and the punch the 770's lack.
Pod De Floor - Major Lazer: lovely. punchy and deep.
Not sure why people say you cant drive them loud enough from a portable device, 85% on an iphone 4 is about as loud as I want to listen.
I'm sure I'm just sounding like a fanboy, what suprises me is how hit-or-miss Philips are, I bought the stretch cans for $30 on sale, I pillaged the pads and sold them, comfortable but dull, but these had potential from day 1.
A/B'ing with the CAL's which I was praising a week ago, no competition. Uptowns are more comfortable, better bass extension (well, now anyway), much better bass punch, more sparkle, clearer mids and vocals. The CAL's are good cans for what I paid (again $60), but the uptowns are gems after a recable.
