I'm trying to narrow down what to bring. I see people are bringing things I own, so I can probably cross of the hd25, amperior, and rs1 from my list. I did get some of the stuff I said I was going to. But I don't know if there's much of a point in me bringing a momentum, UE6000, HD 558, K550, the Samson phones, or anything else people can demo at best buy, sam ash, or audio consultants. Maybe if they want to try it on different rigs at the event. I also got the O2 the other day. I would say it is superior to my Ibasso P2. Hooked up to my clip zip, it doesn't really have enough juice to drive my K701 to where it sounds engaging and full like my heed canamp does. Volume level was very moderate with everything maxed. Amperior sounds more accurate but less fun with the O2, seems irrelevant compared to the other phones now(but was basically my favorite while using the P2). The 558 is much clearer with the O2. The various headphone sound sigs are much more apparent on the O2. People say the UE6000 is too bassy and rolled off. Not with the O2. It can get fatiguing with albums like Eye in the Sky from Alan Parsons. Albums that don't have a lot of bass. I definitely feel the Momentum is the best of the closed phones, but the K550 does have an edge over it when it comes to my film scores. That extra treble energy really helps Rambo, Phantasm, and Star Wars music. The momentum does seem to make the UE6000 irrelevant. However, the momentums are my wife's, so the UE6000 will have to do until she buys the black momentums and presumably gives me her current pair.
If there is anything specific anyone wants me to bring, let me know and I'll bring what's requested.
