Also depends on how you hook up your PC to your receiver and what you are using it for. If you don't use Dolby Digital Live or DTS and connect via digital signal cable e.g. HDMI or optical with LPCM, the soundcard is completely irrelevant.Now if you have a digital reciever with 5.1 speaker setup, then you'd want to get a sound card. Problem is most sound cards are made for headphones users, who would only notice a small sound quality increase. So things like Dolby Digital Live or DTS are usually reserved for $100 cards.
I was unaware that you could even hook an amp up to a computer. I do a lot of work from home so I'd definitely be interested as I listen to music for about half of the day.If you really want to get into the world of hardcore headphones you'll look at external DACs and amps. I could make a few suggestions if interested hasman.
Do the extension cords affect quality?This is worth clearing up too: I did do blind tests. The funny thing is, early on I had actually planned to have 5-10 of them with grades -- it was part of the motivation for buying extension cords. They were labelled for a majority of testing but I removed the tags toward the end so I was just plugging into a random device (AHK let me toggle them blindly on the software side). I scrapped the whole grading thing because the difference was just that noticeable after becoming familiar with each.
It wasn't rhetorical! I'm not talking about the amplifier but about the sound processing. Can I do with one (sound card and Amp/Receiver) without the other? If I run optical from onboard to amp/receiver, will it be less quality than sound card to amp/receiver? I just vice/veresed the question to show how clueless I am.I am not entirely sure if this is a rhetorical question or not, but as you have already said, your Onkyo receiver/amp is acting as an amp which is a very important function for any quality speakers. Just having a sound card in a pc doesn't over the same pump that a receiver is capable of. I took run my pc audio to my home theater system with an onkyo. The audio quality that it is capable can be maintained at much higher volumes than my smaller topping amp for my desktop setup. Receivers always add great versatility! It just costs a bit to bring that function out with more peripherals. Sorry again if the question was rhetorical!I have a sound card that is plugged into an Onkyo Amp/receiver. Is my Onkyo doing any work? or is it acting as a mere pass-through to my speakers, rendering it expensively useless?
Not as much as a salesman would lead you to believe.Do the extension cords affect quality?
