Hope y'all are well.  I have a pair of grado 80's for sale/trade and was offered a trade for both a pa2v2 and a storm little 2.  Plenty written about the pa2v2, not too much on here about the storm little.  what would be your opinions/preferences...Will be running with Ultrasone pro 650's...as...

The 750's are being offered by a forum member...I really wish I could hear these two or find more between them...such a tough decision

thank you!  dang, those are expensive!!  that may push the 750's, but then again, I could save almost $100 on the 650's and use that toward a portable amp and pick up the earpads later...  

I've narrowed it down between these two now...650 is $140, 750 is around $200.  From what I"m reading, the 650's warmer presentation might be better for me at this time, but I"m wondering two things.   First, can one get the velour pads of the 750 and use them for the 650?    Also, does...

What's the in-btween on these?  overall sound, clarity, soundstage?  thanks for any additional input...

I've brought it down to these two based on what I've read, but seen no comparisons of these two.  It seems the 680 isn't that popular here.  If you could choose between these two at pretty much the same cost, what would you do? With the 680, I'll be purchasing a sub $100 port amp.  With the 750...

@HeatFan12...sorry for the confusion.  Yes, no dedicated headphone amp at the moment.  Looking to get a portable amp in the near future.    My contenders right now are the HFI680, PRO 650 or 750.  From what I've read the bass is too much on the 780 which I know is relative though.   I'm...

Yeah, unfortunately those were gone this morning....I was about to get them, asked a question, and they were gone...not sold though which made me question if they were real...would love to see them come up again though...   looks like I can get the 680's for about 190, the 750's for 230, the...

Read a little more today...now down to either the HFI 680, PRO 650 or 750 (can't find much about the difference here), or the Denon 2000...I'm not sure if I should be scared of the bass heavy talk about the 780's...is it a large difference compared to the 680 or 750?   From here I don't know...

I'm going to say up to 200, but could be swayed a little above...   would like 150-175, but again will push a little higher...I found some demo 750s for 200 so that's why Id like to stay around there

I've been reading through here for quite sometime but decided to join in the discussion and ask a huge favor.   I'm currently using some Grado 80s which I'm very happy with; however, I need a closed back design as I need a phone I can use in public as well.   I'm using this headphone for...
