First as far as speakers you could look on ebay for a matching or near matching pair of infinity's (if you can't find the same model just try to make sure the tweeter is a similiar design from infinity). As far as recivers I own two HK's-a 235, and a 340 which is still in the box and has never been used. I don't like the fact that HK's really seem to be weak on power despite the fact that they are high current(the high current allows them to have extra power for transients but ONLY if you're speakers are well matched with the HK amp to begin with). Unfortunately even with a very brief test with a basic 16gauge cable my Hk235 was not able to drive my ascend speakers very well (and in stereo mode to boot)-and that was with 50w and as a comparison my nad 315bee 40w amplifier drives the ascends so well that I can not turn the volume up more than 1/4 MAX because it is so LOUD. I don't think the HK's are horrible or anything but to my thinking Hk receivers will give you better sound than say a sony,or maybe a pioneer (although I like pioneers brighter,detailed sound) but HK will not actually give you more power (except as reserve power/current which is useful only AFTER you have matched the HK with a speaker that has a reasonably easy impedance and also a frequency response that matches the HK well). I do think that JBL and probably infinity speakers are probably better matched to Hk than other speakers (which makes sense since they are all made by the same company).I think the best receivers sound wise are :marantz,denon,yamaha,pioneer,and onkyo. Due to all the complaints online for pretty much every reciver I have ruled out onkyo even though I like their sound a lot-because they run hot and that is usually not very good for audio components in the long run. I like marantz's sound best,followed up by yamaha,denon,pioneer. Because most receivers are now made in china and you hear complaints I've decided that if I buy another receiver I will probably buy an extended warranty to go with it. it seems Yamaha may be a little more reliable than others but that's not including their lowest models this year as they have shipped production to china like everyone else and I have heard a few complaints as to receivers being doa (although if you buy from a good dealer you can just exchange for another if you get a doa unit and I wouldn't be TOO concerned as I'm talking about 1 or maybe 2 reviews I read).I like yamaha receivers the best overall because like HK they actually do have a high current design and I like them because they will sound good no matter what seakers you match them with. I do think Marantz is a much better sounding receiver but that doesn't mean yamaha is bad sounding because I think they are GOOD sounding. Denon's sound good too-they give you some of the "smoothness" of the Marantz but give you lots of features that Marantz doesn't offer in their similiarly priced receivers.The pioneer I heard with some JBL speakers was very dynamic and exciting sounding but some pople want a smoother or more "audiophile" sound. I think a yamaha 765 or 1065 would be the easiest choice,followed my Marantz which has the best sound of the lot but fewer features than most,then denon,then pioneer. Just make sure to buy from a dealer with a good reputation and a very good return policy (like 30 days no questions asked,full refund or credit option) so that if you don't like it you can return it-and personally if you are going to be using the receiver a lot I'd suggest an extended warranty.
