my 2 sense:
Someone suggested to just buy "any AVR" because Totems are not difficult speakers to drive. It is true that every one of their columns up to the Sttaf are rated at 8ohms... the Forest dips down to 6.2ish at its lowest and the winds at 4 ohms.
The AVR in my opinion WILL make a difference on the quality of sound that is being outputted. I am just saying this because I just recently changed my system from an entry level Yamaha to a SC 27 Pionneer Elite reciever. WHAT A DIFFERENCE.
I have the Sttaf hooked up to the Pioneer and in Stereo (which is how you should listen to music) the sound is... well..... unreal. They are the best, most detailed sound that I have heard from this price range of a speaker. The speakers are very detailed and crisp. Very nice for classical and other detailed music.
Now... I am upgrading to the Forest... just because I am hard to satisfy
Anyway, my point is that an AVR will make a difference in the sound.... Just like hooking up a Sony and then a Krell..... you will see a difference.
Another comparison which is night and day. My pioneer receiver is fantastic and pairs really well with my Totems... but on the other hand... listening to music through a Macintosh product is night and day. The sound is WAY better compared to my Pioneer. But, I can't afford a Mac so I have a pioneer. I picked up the SC 27 for $1800 CAN through a nice deal. Normal price was 2400ish. It's not a cheap receiver by any means but my point is that usually... there is always something better out there (MAC) and it is worth shopping/demoing different products. Any AVR will not do. Don't settle! Get the best that your money can get.
