Nice info man, I'm completely happy with the RX700's, I might go to a set of HA-DX3's in the future, a buddy said he could sell me a set for about $60...so I might consider them. But after breaking-in my 700's and removing the felt, they perform quite well, though i still need bass boost to get decent bass out of them for the kind of music I listen to. I've vastly depleted my bank account and increased my music collection with lossless goodies now as I can hear a difference quite easily.
I'm considering a few options for better sound output though...one is the Auzen X-Fi Forte 7.1, has the X-Fi goodies I'm used to, better components for the primary front channels, dedicated amp for headphone output, it's price is the biggest issue I have at this point.
I've also considered a dedicated desktop headphone amp, but at the same time...bleh, I'm not that kind of audiophile and to get anything decent or what would be considered worth while, I'll either have to go used and take a risk, or buy new at $200+++ and take a risk, too many variables and opinions.
Another option is finding a reciever and using it for a monitor shelf too, which would actually be nice to have. Though, I wouldn't necessarily want to power it using SPDIF from my X-Fi and lose my mic-in, which is required for my clan gaming. But I suppose a 3.5mm to RCA for input would work out. Use the line out for my X-230's and be good to go. Right now this sounds like the best option I have atm, unless I can find the forte for under $100...I just can't justify buying it...plus it'd be nice if the X-Fi Titanium front panel had amped headphone output too (i've read that it does and doesn't...so I dunno what to take from that, plus at 80 bucks..not a good value imo), but instant switching to Game mode and Cmms-3d mode plus volume/gain control on the headphone and mic circuits would be handy as hell.
I know there's much better than my current JVC's, but I'm so damn happy with them, and some EQ tuning, I can't believe the difference between these and the HPA2's....not even funny. She can keep them damn HPA2's...I didn't know what I was missing lol, and that's an a cheap set of cans.
