Finally got the Grado Bowls mounted on the Porta Pro's
Looks great! Does the balanced Porta Pros sound better from balanced source than single-end version? I don't have any dap with balanced out, nor have any experience at all about balanced sound. I'm thinking about recabling my portas aswell, I'm just not familiar with headphone cables and don't know what would be a good cable. I'm a bit surprised that kramer mod didn't make sound improvements for you. When I first time did kramer mod years ago, and I didn't even have too trained hifi ear yet, but to me kramer mod was like a revelation, almost like night and day difference in sound quality. But anyway, we all hear differently and fun-factor is the main thing about modding like you said.Ok guys here is my take on this classics.
One evening of fun and recabling to balanced plus adapter to 3.5 is here. Did Kramer mod as well but honestly isn't much improvement there. Main thing I had some fun to doing it.

Oh they're brand new? In that case apply some hours burn-in and listen if you hear any improvement after that. I was actually quite underwhelmed by my porta pros, until last week after I applied some burn-in. Black edition is my second pair, and they're relatively new. I did kramer mod almost right out of box and I wasn't too impressed how they sounded after that, so I but them aside, and until last week I thought I'd give them some proper burn-in, and then magic happened. Maybe that was reason why I had such big effect with kramer mod with my first pair, than I had with my second pair, because they weren't properly burnt-in yet.Thank you. You're right looks great. They actually looks much better then they sound
They definitely benefits from balanced source, more highs and clarity. Not more by big margin but you can distinguish it. I just actually got them, They brand new. So may be because I wasn't familiar with their performance before they not impressing me much. To sounds okay you should listen them on a high volume which is not ideal in many situations. Anyway I'm not regretting for getting them since having fun was the main reason
Sound had become quite loose and messy. Maybe slightly warmer too, and fine details seemed to be reduced slightly. Not good... So I thought some sorbothane would help. I put little square piece of sorbothane duro 70 to center of driver since diaphgrams were removed, and trimmed it thinner but thick enough that it would touch the driver grills. Results? Fantastic! All that looseness was gone, and clarity was back. Now sound is very smooth but very detailed and natural. Soundstage has good width and surprisingly good depth too, with very decent imaging. Succesful mod, afterall! 
I found that headband from flea market years ago, and I believe it's quite similiar to parts-express headband. However it had one side broken, but I fixed it simply with electric tape. I love how light it is, and no more hair issues like on portapro headband.
