sony str k750p and av123 x-ls

[slydog64]

Im thinking about upgrading my speakers to the x-ls speakers and was just wondering if my current reciever would be able to power them properly. Currently I have 2 different sets of 5.1 speakers that I bought in a box set from best buy (I know, bad choice, but I got them discounter). I dont really watch too many dvds, I occasionally do and the surround sound is good enough for that. My main interest is music on my computer, as I will be placing the speakers on the side of my desk, about 4 feet apart.

So overall, just wondering if these speakers would work well for this situation and if my current receiver would be able to power them. Or if I would be better suited to upgrade my receiver first and speakers later.

BTW, reciever is rated at 575 watts total, 100watts per channel I believe, total not rms of course.

Thanks, Greg

Bump, just want to know if I can upgrade to these speakers without any problems.

I took a look at the manual and it lists 20-20K power as 90wpc (and Sony's power estimates are often optimistic). The X series are not too demanding, (though they are lower sensitivity) but they will definitely do better with more power rather than less. If you are looking for reference levels, you probably won't achieve them with this receiver without it straining, however for a smaller room it will probably work fine. If you are only talking about one pair of X-LSs, then it should be no problem at all.

thanks for the reply, anyone else got any other ideas?

I think it entirely depends on your listening habits. If you play at moderate levels you will be fine.... If you like to push the limits you may run into trouble.. You'd probably notice that first as a harsh.. tiring sound.

I used to use my Sony reciever with my X-LS.

It was a 100wpc STR DE-935

It did an ok job and could play at just about any volume you could want except for the most extreme.

It did get harsher the louder you went.

The Yamaha does a much better job IMO.

In case anyone is still reading this, I just found this post. This is the same crappy receiver I am running my Ref 1s and mismatched Infinity Beta 360 and 2 odd Sony surrounds. I have had it for 5 years. The results are not bad.

Running a 4ohm load is on an amp not designed for it is risky, turn the volume too high high and it can overheat. The xls are 8ohms I think, so this isn't an issue for you. The Sony audiably clips at 85db and I keep the volume low (under 50 in the receiver). Otherwise, I get a wonderfully detailed, if harsh and not-loud-enough sound.

This receiver has only 1 crossover setting, 150Hz (or around there). I think this high a crossover helps with the lack of power somewhat, at a cost of a huge hole between 150Hz and whatever your sub tops out at (mine is crossed over at 100Hz). Going subless and "Large" on the xls will cost you power, but fill the hole.

If you have limited funds, I would certainly buy the xls before upgrading the receiver. If you bought this as a "home theater in a box" throw out everything else that came with the package except the DVD player (the satellites can work as surrounds) - even replacing the wires will have a huge improvement.

That said, I am waiting on a Yamaha 5960 I just bought on e-bay for $110 shipped.

Alright, heres an update, I bought some klipsch speakers from bestbuy discounted to tide me over until the speakers were available from the website. Im thinking about returning these klipsch ones and ordering the x-ls now.

Im open to upgrading my reciever but I dont know what to upgrade too because I pretty much only listen to much off of my computer. I have my pc running through my receiver now. I dont know what is the better upgrade, a sound card with optical out, or a new reciever.
