Soundcard + Speakers + AMP + Headphone Possible? - Page 2

post #11 of 29
If you get an old receiver, there's like a 90% chance it'll have a "tape out" that you can hook your surround speakers to. Tape Out is basically a y-splitter inside the receiver that's after the source selector.

This won't have any significant sound degradation, and run it directly from your soundcard to minimize connections. This is assuming your speakers are self-powered right?

Also, +1 to monoprice. They make quality stuff for cheap.

If you connect front or rear headphone with the line out on the rear, the soundcard will probably default to headphone output only, but go ahead and give it a shot before you buy additional cables.

edit: go ahead and get a 3.5mm to RCA, because you'll need that for the receiver regardless.

Bud, I didn't quite understand what you meant to say on the line I marked bold redface.gif Did you mean the front headphone port on my computer? I dont have any rear headphone ports, my sound card only has the Green, Black, Orange and Blue Ports behind, the Black and Green is being occupied by the Current Surround Speakers which needs a Front and Rear output..

However on the creative control panel there is an option to drive the Front Headphone jack and rear green line out simultaneously.at once, I dont know if that's bad or effects the quality much, The front is headphone out and although its HD Audio, like you I think the quality output would be lower then the line out on the sound card. So its better if its all done from the rear i/o of the card and I rather use the rear green line out port on the back to go to the receiver. However that and the black one is being occupied by the surround speakers.

Yes the Surround speakers are self powered, They receive their power from the subwoofer, that's where the Green and Black line outs also meet. From the sub, I also get an separate dial from which I can control the speakers.


PS: do you think I should grab that 3.5mm to RCA off ebay, they say they are gold plated but I can look around more, quality should be good right? I would go for monoprice but the shipping outside the US is a killer $40 for that cable. tongue.gif

With this setup I can actually have both run simultaneously.

And I've been looking at the old Denon HT receiver that I have, and noticed that I can have the headphone jack activated for any of the inputs, I just have to do it manually. Meaning, I can go 3.5 > rca into my receiver and then either leave it as the default output (HT system), or press the "output" button on the remote and it will change the output to the headphone port (regardless of what source its coming from). So you might try to see if you can find a setup like that, because that would solve your problem without a splitter.

Good luck man smile.gif.

Yea guys, I think my amp would support switching between the source signal, but I only saw 1x 3.5mm port in the rear, So something like this.. Computer - > Amp -> Surround Speakers + Headphone wont be possible since my surround setup needs another 3.5mm for the rear speakers. I am also not sure if leaving the speakers to the computers sound card would yield a better surround experience then the amp which does have dolby pro logic but the rest is stereo, which is fine for listening to music on a headphone but no reason to run stereo signal on to a surround speaker setup.

TAPE OUT connectors have no volume control.
Yes, a "Y" splitter will work just fine from the LINE OUT of your sound card.

There are very few "black" amps/receivers that are "Vintage" . Anything produced after 1980 is "garage sale used HiFi". Exceptions would be McIntosh, some Marantz.. Prior to 1980, (1965-1980 were the "Silver" years) stereo equipment was sold based on how it sounded (ie. stores had "listening rooms"). After 1980 HiFi equipment was sold based on "Features", as sales became more and more sight unseen. After 1980 engineering went into designing those "features", to the detrement of overall sound. Multi chanel sound and royalties to Dolby, Bluetooth, Blueray, etc reduced the funds available for engineering development.

Could you look at this amp and tell me how its supposed to connect to the LINE OUT of my sound card.or if I may have any other options then using a Y 3.5mm splitter altogether?

this guys selling it locally, its a denon avr 2600.



oh, and thanks for the little info on amps, appreciate it a lot. thumb.gif

That amp has no digital processing, so everything is being done by your soundcard. The RCA cable off ebay should be fine, just make sure it doesn't add any noise when you plug it in. Just split the line-out in the back like you were going to do before. If you were to find a slightly newer AVR with an optical input, you could just run an optical cable from your motherboard to the receiver. That would allow you to use the DACs in the receiver instead of your soundcard, which I assume is fairly low-end.

Edit: I should also ask why are you buying a receiver just to amp your headphones? Is it an amazing deal, or are you planning on buying passive speakers to hook up later?

Really? I thought it had Dolby Digital and all the fancy stuff. So the AVR/Amp is not really doing anything like Mixing things via Dolby and all the other sound processing stuff inside to give me a improved and better experience then I would get just by plugin the headphone to by Sound card? Only the sound card is working? So I Should look for something a bit newer, like around what year? I think this one is from the mid 90's, Something from 2000's? I dont think thats a period of time that amps were known for their kick ass quality? any suggestions? Sony?

My Sound card is a Creative Xfi 24Bit, I am not using the motherboards Realtek, so dont think optical is an option since he sound card doesn't have optical? or am I wrong?

I will be honest why I am buying, for now its to run my headphones, being able to control the headphone audio levels and give me an better experience then just the sound card, I know most of these old stuff will sound in par if not a lot better then some cheap to midrange $50 - $200 headphone amp? and later slowly I can purchase better passive 2.1 bookshelf speakers and a sub and phase out my current speakers, but I dont see that happening over night. Slowly maybe next year or so.

How much do you think that amp is worth in good working condition? How much would you suggest I spend? If its a newer amp I may go up to $60 -$80. is that okay?

The headphone ouputs on AVRs are usually of reasonable quality but can vary from one manufacturer to the next. They aren't the main focus of the amp so have far less cost/design dedicated to them compared to the speaker output stages.

The two chips that are important are the DAC and DSP. Digital audio converter changes the sound into analogue, and a better chip means better and more accurate sound. The DAC in even an old receiver is probably better than what's in your old sound card. DSP is digital sound processing, and that's where all the surround/reverb effects come from.

One part of headphone/amp matching people overlook is impedance matching. The line output of the amp should be less than 1/8 the impedance of the headphones. That's one of the reasons the 600 ohm beyerdynamics are usually reserved for home hifi use. If you got the 250 ohm DT880s, the output of the amp you use should be under 31 ohms, otherwise the amp will change the sound slightly. I have no idea what the output of the headphone jack on that Denon 2600 is, but I believe most are in the 30-50 Ohm range. Something like a $100 Schiit Magni would be a better headphone amp with its 0.1 ohm output impedance.

You should only look at newer receivers if you are willing to use your motherboards optical connection, because you would need to feed a digital connection to the receiver. You may be able to enable your motherboard audio and use the soundcard at the same time, but creative cards sometimes don't like that. Things to look for would be optical input, dolby headphone, subwoofer out. Does that Denon 2600 have a subwoofer output? I doesn't look like it from the picture, but I can't really see.

I would just get some nice headphones and an amp like the one I recommended for now, and worry about a receiver when you actually want to upgrade your speakers.

Found a manual in german and it seems to indicate it has a subwofer / super wofer output.

here's some info I found on it http://www.wire-x.com/2600.htm (although it doesn't mention a sub unlike the german manual)

I don't think my motherboard supports optical, i built it as a cheap htpc just for browsing the net, watching movies and music with a mid level amd graphics card, so doesn't have very powerful components.

So about the dsp and dac, so the dac will convert the sound however the dsp wont process and add effects? but I should have significant improvements then just driving it from the headphone jack or sound card non the less?


Anyway its not the only amp, its just one that caught my eye among some oldies. how much do you think its worth?
post #20 of 29
No idea what it's worth, check ebay keeping in mind the exorbitant shipping costs. What is the exact model of your motherboard?

Everything that converts a digital signal to analogue has a DAC. When you run analogue cables from your soundcard, the DAC in it has to convert the signal first. If you got DT880 250 Ohm headphones, that crappy soundcard probably wouldn't be able to drive them to sufficient volume, so the receiver would act as your amp. However, the receiver will not be doing anything else to the audio because it already received it in analogue form. If you were able to pass digital signal to a newer receiver, it would bypass your soundcard and do all of the conversion with the superior DACs on the receiver. What the expensive amps have is more power (which you don't need), but also better components and circuitry.
