Re: Asus xonar STX question
The RCA outputs are unamplified, if they were amplified your SP2500 would be doubly amplifying the signal leading to significant sound distortion. So you can setup your new stereo amp to drive the passive speakers, and use the card's internal amp for driving your headphones via the 6.35mm jack at the back.
Re: Asus xonar STX question
Yes that's what I thought as well, the manual must be wrong. So if I get this right I would use an RCA interconnect cable to connect the sound card with the stereo amp correct? Do you have any suggestions for a decent amp and a pair of bookshelf speakers for around £500?
The corsairs are so and so not very happy with this purchase...needless to say that they make a hissing sound even at low volume
Re: Asus xonar STX question
I wouldn't really be comfortable guiding people on shelling out £500 on audio equipment since it's a highly subjective choice. whathifi.com has extensive listings on the various hifi amps and speakers on the market, have a dig through that and see if there's any equipment with the apparent characteristics you personally prefer.
