How well would this old amp work?

post #1 of 5
Thread Starter 
I have an old Optimus STA-300 (Radishack brand, 16 years old) stereo receiver. I'm just wondering how it would work as an amp for my soundcard. If I use it with any headphones, would it make any noticable difference than if I used my soundcard alone? I want to hear expert opinions

the only way to know is to try it. Most speaker amps/receivers/components will not have as good of a headphone output as a dedicated headphone amp. But it may be better then your sound card.

It gives me alot of response out of some cheap-o cans. It doesn't have a Mid Level selector, but I think it's better sounding than just a soundcard. Any other opinions?

It will give you better volume deffinatly, as for the quality it wont be as good as a dedicated headphone amp but it will have a warm sound

I use mine all the time on my system. It sounds great with a pair of Mimimus 7s or headphones.
