Have you tried going straight from the soundcard to the amp to rule out a problem with the mixer (do you need the mixer?)

I thought it was always good to have a Pre amp?? Maybe i should go strait to here ... that is a good idea... let me go to class and i will come back and try it and get back to you guys ...


what I am looking for is for this to sound as good as it should ... 75 per channel... the speakers can take 2-- watt peak ....


Edit 1:
Any one else with experience or good ideas would be helpful smile.gif

And every time i have a windows sound i get a poping sound from the speakers ... why is that ????

it happens only in startup or always ?

check the cables maybe you have and EMI there (or a nearby WiFi device like a router , or maybe the speakers are damaged by faulty electricity

Speakers are 8ohm, and want a good bit of power.

The amp you have picked has 75w RMS @ 4ohms, so its around 37-40w RMS at 8ohm (as a guess).

Your amp isn't powerful enough, its that simple.

No its when i click on the speaker on the bottom on the GUI and test to see if sound is happening ... even if i have music playing already or something ... and I have my Wifi card there ... but i only get it when cretin sounds happen ...

@ pioneerisloud what amp would u say to get and i don't understand ohms .... what does it mean?

Considering you've got 8ohm speakers, the DTA-100a would be the better option between the two. It'll provide 50w RMS @ 8ohms, compared to your roughly 38-40w RMS out of the amp you have now.

Either that, or get 4ohm speakers.
