Main setup:
Speakers are one of three, Mission Freedom 770 IV’s, Polk LSi25’s, or Polk SDA-CRS (stock XO, SL2000’s, Blade/Blade model). Electronics are as follows: for the LSi’s and SDA’s, a Technics SU-v75 acting as a phono preamp, into a Yamaha RX-v665, into a Crown XLi800 power amplifier. For the Missions, I have a Lafayette LR-1100. Turntable is a Technics SL-3200, with a Shure M97xE. Cables are generic/soon to be replaced garbage.

I've always thought the goal of high end audio was not to have your neighbors bang on the wall and say, 'Turn that darn music down' but to have your neighbors bang on the wall and say, 'Tell your friends to go home and you can practice later this week'.

    LSi25s, sorry I should have specified that. This amp is the one suggested by tonyb:
    http://www.usaudiomart.com/details/649391951-parasound-hca1200-power-amp-205wpc/
    THis one is more powerful, but it is like s $300, and I would have to save for a long time, so if I can get this one for way cheaper and have it work I would like to.

    Will the Adcom work...of course it would. Will it power your LSI's to their full potential...not even close!

    Looks like the auction ends in 4 min so you'll probably not get to read this in time but I'd just wait for something nicer and more powerful. I suspect you'd like the Parasound WAY more than the Adcom.

    However, it also depends on your listening habits. If you like normal listening levels (like you could still talk with music on in the room) the Adcom or similar might be just fine. It won't be the best but shouldn't be something you immediately regret. If you like turning it up to 11 then avoid the Adcom and similarly powered amps. You're going to really have to push it to get what you want.

    If you've already bought it though, then congrats and don't worry about it! If its just what you needed then great and if you don't like it then it's all part of the audio journey, someone else will buy it no problem.

    Ok. I didn’t buy it, I didn’t realize it ended. Also, a pair of infinity speakers I’m going to sell turns out to be worth a lot more money than I thought, so I can get an amp for up to (estimating here) $500, any suggestions?

    Yeah, the one you posted, the Parasound. You won't find a better amp for that price. Take the extra coin and buy decent speaker cables if you don't have any yet.

    I’ve got 16 gauge monster cable my dad gave me and some monoprice 12 gauge pure copper cables, and I’ve got a fifty foot hdmi cable (the definition of overkill) and I have a 16 foot rca cable that is for car audio already. I’m going to see about buying that amp in the future, and if there are any cables you guys think I need, or anything that will not be good enough, then let me know. I’m going for sound quality, not just super loud music, so I want the best. Also, I have a kicker 12” that I found at the flea market for $20 that I am running on that amplifier that went bad since the left channel still works, but will this hurt the quality in any way?
    Thanks so much for all your help guys.

    I don't understand your subwoofer question very well. Sounds like it's kind of hacked together anyway so don't worry about quality.

    Toss the 16agw, and the HDMI cable, both are useless in this situation. The Kicker sub should stay where it was intended to be: in the car. Flip it for more $. Buy a HT powered unit (assuming this is for a HT build). If it's not, then don't bother with the sub and use the powered, integrated subs in the LSi25s.

    I’m using the hdmi cable with an adapter from my iPad and then into my receiver as my reciever has a better dac than the cheap one in my iPad, but if there is something with this that will hurt quality, then let me know.

    ok, so I’ll drop the kicker.

    This is mostly just for stereo however if I find a good pair of surrounds I might hook 'em up. Generally I use my mains (not the polks since I don’t have an amp yet), my center, and one of the Polk subs. I would use both subs, but the right one doesn’t work and I gotta get it fixed, but the power amplifier comes first so that I can actually use my speakers.

    I also have a Velodyne ten inch powered subwoofer, should I hook this up as well because I have it? Or is it not going to help a lot?

    And one more question (sorry, this is a long post) what is wrong with the 16agw cable? It is pure copper, and I’ve used it for a while now, and I haven’t noticed any difference in sound when I started using the monoprice cable. I’m not saying your wrong for saying why I should get rid of it, I’m just wondering, what is wrong with it?

    Thanks again for all your help.
