not bragging but this is my thang...

as a composer...

I chose an awesome Sound Blaster
And a HIGH END external HI-Fi Amp...

This in addition to an onboard soundcard is ABSOLUTELY PERFECT
even if you compose
1 to ASIO playback
1 to RECORD from it
and bacground - lowkey multitask.

Your microphone goes into your AUX sound card
and its speaker goes into the AMP

PS: HI-FI amp
Just means "livingroom stereo"
