Hi to all involved, new guy here. I have a question of sorts. I need a device that is similar to Creative labs sound blaster X7 Link: https://us.creative.com/p/amplifiers/sound-blaster-x7-limited-edition My set up now is my computer sound card that i have been using since the creative unit died. Sound card I have is that Asus Xonar Essence STX. I need a device that has the ability to hook up a couple of books shelf speakers, have a pair of klipsch RP-150M units, device spec sheet: http://assets.klipsch.com/product-specsheets/RP-150M-Spec-Sheet.pdf Also needs to have a good built in headphone amp, specifically to drive the Sennheiser HD 800S I use my headphones with the Asus card now but need something that has more power for the headphone. Does such a device exists that has all the features mentioned above, do i need to be searching for a couple of devices to get a good setup? Any suggestions is appreciated. Thanks.
