Hello, I'm planning to buy VHP-2 to use it with HD595 thru X-Fi Elite Pro (Modded with LM4562 & Black Gtae Cap) which I think a really great source . . . Is VHP-2 a great combo with sennheiser HD595 (50 Ohm)? Is it enough to use VHP-2 without VAC-1 ? or any other opinion?

I had HD595 connected to line-out1 in the X-Fi XtremeMusic card and I'm looking for X-Fi Elite Pro with external I/O box that include 1/4" jack for headphones. So, which better to connect to: ----> ( line-out1 OR 1/4" jack ) ?

I'm wondering wether to buy an X-fi I/O front bay to my XtremeMusic inorder to plug my HD595 into front headphones jack, but will I get better amplication and sound quality if I connect HD595 to front headphones jack of the bay instead of rear jack? Is it worth to upgrade for this purpose ?

Is there a sound card that can drive 300 Ohm without need for external Amp? if not what is the best Headphone Amp for this combination : HD650 + X-Fi XtemeMusic

PLease somebody tell me, I want to buy HD595 from amazon.com, but I need the 50Ohm version, Is it 50Ohm or 120Ohm version of HD595 in amazon.com?
