What amp should I use for LSi25’s?

As you probably know I got some LSi25’s. I had a onkyo amp that could push 4 ohms and sounded pretty good with them, but it bit the dust yesterday (it wasn’t the speakers that caused it, I think they were just the last straw. It has been having problems for a while.) anyway, I now need a new amplifier. I can’t decide if I should go with a power amplifier, or get a 2 channel, or another avr that can push four ohms. Also, what wattage should I look for? I can only find maximum wattage ratings on the internet, no rms ratings. And then, what brands/models should I look for? I would love to get another Yamaha, onkyo, or Denon, as I have had good experiences with them in the past, but I’m okay with other options as well. I also need something that is high quality, and sounds good, and is relatively new (late 90s is as late as I want to go) I would prefer not to get a tube amp, just because they are more expensive and may not blend well with the types of music I listen to (classic jazz, classic rock, and (occasionally) hip hop). Unfortunately, I need this all for around $200, I would prefer not to go over that number. Thanks for any replies and help you guys can give me.

There isn't an AVR made that is truly capable of driving 4 ohm loads. The 4 ohm option simply limits current in an effort to save the AVR from damage. So, I've made your decision easier, you need a power amp.Political Correctness'.........defined

Ok. Would a 2 channel amp (the kind with an a and b channel, where both are just left and right) work? I would prefer not to have to use a power amplifier because I can’t find any that are decent for a good price that aren’t a couple hundred watts.

You will need a pre amp if you buy a power amp. Otherwise, you can use an AVR for the pre amp to go with a power amp. I'm afraid I have no suggestions in your price range.Political Correctness'.........defined

Ok, thanks

Is there really no AVR that you can buy that pushes four ohms, or is that just in this price range? I might be able to find a deal at one of the local flea markets to buy a higher end one, but if they don’t really push four ohms then it wouldn’t really work

I already have my Yamaha rx-v665 that I can use as a preamp if I get a power amplifier, what I am asking is can I use a 2 channel like this amplifier: https://cnet4.cbsistatic.com/img/fuBZuqO5_h4RAlzDtCzRB_xzK7E=/fit-in/970x0/2013/09/13/8a2c158e-6de1-11e3-913e-14feb5ca9861/back_large.jpg
This one is almost the same as the one I used to have that died yesterday
Sorry, my question was not very clear.

No, and that's a big NO. That's a receiver, not an amplifier, and a very weak one at that. If that's what you used prior, or similar, that's why it's toast now.
You need an amplifier in conjunction with either a pre-amp or receiver with preouts. Then you'll need 2 rca cables to hook it up.
You have, in my view, too much speaker for the electronics you have to run it. This leaves you 2 choices. Sell them for some other speaker that is 8 ohm, or save your coin and buy a used amp. There is no work around to powering them correctly.HT SYSTEM-

This is one example of what you should be looking for.

I have Adcom GFR-700 AVR and it pushed my lsi15's wonderfully. -
SORry, I meant I will use that as my preamp, not my real amp. And ok, so that onkyo (or a similar amplifier) won’t work. I only drove each speaker for a short period of time with either of those amps, because one died (finally) and one you guys said was not sufficient, so I haven’t used it since. So I’m going to leave them sitting, and for now I’m going to save up. Until then I’m going to use some Boston speakers. I will check out that amp you linked. Also, those infinity speakers are apparently worth a good bit more than I thought so that brings my max price to about 400-500 dollars. Thank you all so much for your help, if you have any other suggestions please let me know.
