Looking for speaker recommendations that I can purchase on Amazon.com


Budget: under US$5000 and would prefer a price point of less than $3000/pair. The most expensive speakers I have owned so far are Polk RTi A7's, so this will be a big jump for me.

Purpose: music

Room: I tend to move every few years, so I don't want speakers that will work best only with very specific room conditions. Currently, I will be using these in a medium size room of about 22 feet x 18 feet. The room has carpet and window treatments.

Music sources: CD's, lossless music files stored on computer and MP3's when that's all I have available. I don't ahve any SACD's yet, but I plan on purchasing more high quality music once I have this system set up.

Music styles: acoustic, Indian classical (sitar, srangi, flute), alternative rock (Portugal. The Man, Sleeping with Sirens, etc.), older rock (e.g., Rush).

The speakers should sound good playing the Tanpura (aka Tambura). It is a classical Indian accompaniment instrument in the "drone" category. (https://en.wikipedia.org/wiki/Tanpura) Example of sound here:

With bad equipment that sound is fatiguing to me. Live it is beautiful and relaxing. Hopefully I can find speakers that will do it justice.

Personal Preferences: I am looking for non-fatiguing, warm, musical qualities. In another discussion topic here on this forum, @mtrot and I agreed about "smooth, sweet, soft, silky treble" and "shimmery, airy cymbals" as goals.

Amplifier: Yamaha P5000S

DAC: to be determined, but probably something like the Teac NT-503

Finally, the speakers of choice must be sold on Amazon.com, Bestbuy.com (or possibly some other similar retail website). I have personal reasons for this limitation. It isn't always true that I will need to buy all my speakers or audio gear from one of these sites, but for the moment, it is a requirement. Please don't recommend anything that isn't available on one of these sites. Thanks.

The Emotiva's are good. Really good. I have a pair of the T1's and absolutely *love* them. My neighbor went out and bought an identical pair within a few hours of listening to mine.

Emotiva also have a 30 day return no questions asked policy, so if you don't like them you're only out the return postage (which I'll admit might be $100 or so, these speakers are big :-).
@clarinetmonster2 Thanks for those suggestions. In regard to the SF Chameleon, I don't really like the way they look. Personal preference. But I don't think I could have made myself buy them ;-)

    You are spot on. Amazon is best for mass market average at best products not hifi gear.  After all Amazon is a Walmart competitor.  Having a good relationship with a local dealer is invaluable. You can demo products in your own home and make the choice that suits you.  You can also usually trade in your old gear towards upgrades. 
    The Yamaha P5000s works best with Yamaha club series speakers. Great set up for an arena or night club where quanity trumps quality. Return the yahama if your end goal is quality sound. 
    Best Buy Magnolia is ok. Some products are good. The problem is the staff. Not experienced not super knowledgeable and have limited information about products they don’t sell. 
    My first system was from crutchfield, JVC products with infinity speakers. Next stop was an upgrade to carver gear and Cambridge sound works tower 1s. After 10 years I upgraded to all Krell from source to speakers.
