Yes appologies for the confusion. By multi-channel I did in fact mean Surround Sound amps.
Nothing wrong with surround sound amps, but as with everything you get what you pay for, (to an extent), and obviously an amp with 6 channels costing the same as a standard stereo amp is just never going to be as well built or specified. All the things that make an amp good, (ie the topology, output devices, input stages and power supply), cost more when better quality parts are used. Especially the power supply, which actually plays a huge part in the sound quality of an amp.
By the way, power output in Watts is irrelevant to sound quality in amps. It's an amps current capability, (especially in to low impedance loads), that's important. Current capability is directly related to the amps ability to control the speakers connected to it.
The term amps is confusing in your post, gezmoor. I think we need to start clafiying between amplifiers (big metal box with knobs on) and amperes (measure of your much valued current). Or maybe it's only me that's getting confused.
Ive taken some pictures of the stickers on the back of the speaker and amp. Speaker model is S-Z93 and I searched them on google and found a video with them in:
A shame the speakers are in poor condition (at least visually).
That's just text wrap from the line about, read as "stereo, double cassette deck, amplifier"
Almost certainly, assuming your sound card has a 3.5mm output (most cards do), and assuming the amp takes RCA input, then you just need a 3.5mm to RCA stereo audio cable, such as this one. Cheap and nasty equivalents also available at your local Maplins.
That midrange unit (the middle sized one) is shot. Not going to be reproducing anything worthwhile from that unit.
The dent in the middle of the Bass unit isn't relevant. It's just a dust cap and plays very little part in the overall sound of the speaker, (affects off axis response somewhat towards the upper part of the drive units band though).
Ahh.. cone tweeters, I remember them well.
Not surprised those speakers sound bassy. Cone tweeters have practically no extension, the mid range is going to be sucked out completely on the one speaker with the damaged drive unit. So pretty much most of the output is going to be from the bass unit.
If you turn them up enough that midrange unit is going to fall apart completely.
With respect to the OP, cheap and nasty Maplins varieties are all that are required for a system like that. Gold plated plugs are going to be a waste of money. IMHO of course.
This is more than good enough for the sytem in question.
Bose are far from the best when you move into true Hi-Fi systems
I got rid of 10,000 UKP worth of Hi-Fi setup when I left UK but I am sure the Linn Sondek + Lingo + Aro + Troika, Naim 52 + 180 and Ruark speakers I had would have changed your mind there
The phono plugs on the amplifier aren't gold plated, you'd be wasting money on any cable with gold plated connectors. Plus the audio quality improvements of the cable Bob linked to are going to be wasted on the system you intend to use them on.
If you were looking at standard phono cables I would say go ahead and buy the better ones as they can always be used should you get better equipment in the future. Given the cable you need is only ever going to be used in low grade equipment, (no decent equipment will ever use a 3.5mm jack), I seriously wouldn't bother with anything but the most basic of cables.
My recommendation would be to save your money on the cable and bid for that ebay system to get the speakers from it and/or a few meters of decent quality speaker cable, (such as this or this), with the saving.
Ok what Im going to do is go to Maplin and get the cable I need, while keeping an eye on the speakers on ebay. Just incase the cable doesnt work, which would leave me stuck with the speakers from ebay.
