Creative Sound Blaster X-Fi HD review

First impressions bear out the claim that Creative's latest USB audio card, the Sound Blaster X-Fi HD, is one for the 'audiophiles'. It looks as clever and understated as a black turtleneck sweater, and the smooth lines of the front are disturbed only by two large 1/4-inch jacks for high impedance headphones that scream quality.

Around the back, there's more to bolster the X-Fi HD's credentials: RCA stereo ports for line-in and out connections and two optical ports for playback and recording digital sources. Inside, the headphone port has its own amplifier.

It may not be quite as intimidating as the studio-grade M-Audio Fast Track Pro external soundcard but, like all X-Fi cards, it comes with the arguably more useful EAX support for games and Creative's THX-certified suite of equaliser options.

Plus, it's considerably cheaper than other high grade USB cards. Got to be worth a look, hasn't it?

We tested the Creative X-Fi HD in the excellent Rightmark audio benchmark and pitted it against the high end X-Fi Titanium HD internal card and the current £25 darling of the audioset, the ASUS Xonar DG. The results were surprisingly lower than we expected. Subjectively, however, it still runs rings around on-board sound.
