Need some Amp help - a little new to properly powering speakers

How happy are you with the sound of the Polk/Rotel combo? 
If you are not yet satisfied; I'd try 'better' speakers with the Rotel, first. 
I'm talking only about 2 channel music here.
I had a Rotel RX-1052 powering old Boston Acoustic T-830 acoustic suspension speakers. That combo sounded great at low volumes. I later upgraded to Canton Ergo 1002 DC bass reflex design larger towers. They need to play quite a bit louder to get everything out of the music. Both are rated at 90 dB @ 1W @ 1M, but the Cantons actually play louder at the same volume setting.

Tim,
We have a similar assessment of moskaudio's current audio system. The speakers are pretty decent and will respond to better quality amplifiers. The Yamaha receiver is the relative weak link in this system. Evidence is that  lower level sound quality improved noticeably when the Rotel replaced the Yamaha. I do believe that moskaudio has recognized the necessity for moving toward a amplifier of "higher quality ". There’s more potential with the Polk speakers to be gained.

Hello moskasudio,
   Let me start of by stating that my technical knowledge can be fit into a thimble,and still have enough room for a thumb!  That being said,how large of a room are you listening in? Also,how far are you seated from your speakers?  That information should be quite helpful.

The very first thing you need to know is that wattage rating on loudspeakers tells you exactly zero about how they sound.  All it tells you is that if you exceed that wattage, you can fry your loudspeaker.  

I think your current setup is actually quite well matched.   People who reside on the Audiogon forum will pretty much universally dislike both Japanese receivers and Polk Audio loudspeakers, but if you enjoy what you're hearing, then keep enjoying them.

If you really want to move up, then begin by listening to as many other loudspeakers as you can.  Visiting the local audio showrooms is OK, but your best bet is to meet other local audiophiles and listen to what they have.  Learn why they made the choices they did, both in loudspeakers and amplification.  

I have plenty of opinions myself, but what you really need to do is get more experience with the gear others own.
