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.

 Take a look at these  Mistral SAG-350 on ebay. I wondered if they sound like B&W speakers. They sure look like they should.

 
@reubent  The Yamaha P3500S was recommended to me on this forum. I recently purchased it. I picked the 5000 over the 3500 because the price was almost the same for either at the time I purchased.

Forum member willemj justified his recommendation of this power amp in part by this review:
See here for a very favourable and rigorously scientific test of the latter model: http://www.homecinema-fr.com/forum/amplificateurs-de-puissance-haute-fidelite/mesures-ampli-yamaha-p...
The review is in French, which I don't read, so I took his word that the amp would be appropriate for my goals. He has heard the amp (his son owns one) and (I think) he knows what I want to achieve.

A couple other people recommended Yamaha amps in the same family, so, having no experience, I took the recommendations and that's how I ended up with this amp. I have not used it yet, but I have used the 801 and it seems to have a nice sound on first impression.

But I am throwing some challenging music at it currently with speakers that tend (I'm told) to be a bit bright (Polk RTI A7).

If I purchase new speakers on Amazon, returning them should not be a problem if the combination of my amp and my musical tastes are not a good match for the speakers.

Regarding AudioAdvisor and MusicDirect, it is unlikely that I can shop either site right now. I did send each one a few questions, but I'm almost certain I will need to stick to BestBuy or Amazon.
@lostbears " Take a look at these Mistral SAG-350 on ebay. "

ebay isn't an option. I'm limited to Amazon or BestBuy for this purchase.

+1 to Reubent's suggestion.
Curious why shopping Audio Advisor or Music Direct is not an option for you.  Both have return periods...30 days with AA and (45?) with MD.
Good luck in your search.
