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.

Regarding KEF R900. I've been reading some reviews. Very interested in these speakers. But this comment raises some questions:

KEF Reference 201/2 vs KEF R 900 | What Hi-Fi? https://www.whathifi.com/forum/hi-fi/kef-reference-2012-vs-kef-r-900
I was reading elsewhere about the 201/2 and some one made a remark that the R900s price falls close to 201/2 that it is better to upgrade to 201/2
Do you all tend to agree with that?

Somebody here questioned the Yamaha P5000S amplifier. The link that I posted to the smaller P3500S showed that that is a perfectly neutral amplifier that measured exceptionally well. Frequency response is perfectly flat, even well above the range of human hearing, and distortion was vanishingly low, even at levels below 1 watt. I bought the 2x250 watt P2500S for my son, and I can testify that it sounds fine: completely neutral and not a tinge of hardness. The more powerful P5000S admittedly has one difference: it has a switch mode power supply to reduce weight and volume. I think that was a perfectly rational decision on the part of Yamaha. I know there are plenty of audiophiles who believe that switch mode power supplies are evil, but I am truly convinced they are just imagining things (do they have measurements to back up their claims, or controlled listening tests?). Big companies like Yamaha, with their huge engineering staffs, know what they are doing, and so do their pro audio customers.
On a more general note, I think those interested in high end audio would do well to stop worrying about electronics, and focus on what really matters: speakers and the room.
