I'm in the same boat as the original poster. I have a nice Samsung TV, and I've pretty much narrowed down my receiver selection to the Onkyo 605. But I'd like to build my speaker collection in pieces, so I can spend a bit more on each part (mains, center, sub, etc.) Current budget is $400-$500 tops, and I'd like to get at least the mains and maybe the sub.
To test out various options, I stopped in at my local Tweeter. There, they were running a special on Polk Audio RTi-10s. $479 a pair, with a free Polk Audio subwoofer (I believe it's the PSW 10 but am not sure). The speakers sounded excellent, but then again I am currently using a $199 Sony stereo that was a present in high school which does not even connect to my TV.
I keep reading excellent things about the Ascend 340s and the PSB T45s, but also good reports on the RTi10s. If anyone can gauge that Tweeter deal, much appreciated.
And if it weren't complicated already, my room setup is in flux. I'm currently in a one bedroom apartment but am getting ready to move in a few months to a house or townhouse.
I'd also like to thank all the regulars on this board. There is so much horsecrap advice floating around on the Net, and in big box stores, and these forums are the complete opposite. I have been reading for the last two months, and the threads and thoughts--on everything from receivers to cabling to HDDVD sales--are continually helpful without being condescending. Muchas gracias.
