Question about Audio-Technica ATH-R70x

Sound BlasterX G6 could do the job here , as it is able to handle headphones up to 600 Ohms according to specification, Sennheiser GSX 1000 is declared up to 150 Ohms. Generally speaking Audio-Technica ATH-R70x is so to say demanding headphone and to enjoy its full potential owners often pair it with separate headphone amplifiers / DACs but then we are entering audiophile category, and that is another story, as said for connecting with PC Creative Son BlasterX G6 (USB) should be OK.
