Suggest to me a receiver and speakers! $2000 budget

You can get an Outlaw 2150RR receiver which is 699.00 but when on sale at Oulaw less with the Maggie MMG Planars and A Sub all for under 2k. The total package would cost 1700.00 and you will have a great reference system if you add source. The 2150RRR is a classic and Maggie MMG are truly a phenomenal bargain. The Outlaw put out 190W into the 4ohm load with no stress and has a phono stage,USB w/dac and tuner and can be used as either preamp or amp. Super product. Can buy the Outlaw with 30 day trial and the maggies with a 60 day trial. Guarantee you you will keep them.

Speakers are so subjective, they sound different to everyone and different in every room. The best and smartest thing to do would be to go to local stores and demo as many brands as possible.

Are you going surround sound? If not, don't get a receiver, get an integrated amp and a nice pair of bookshelves.

Also, buying used = more bang for buck, try  audiogon.com or canuckaudiomart.com

Do you have to have bookshelves?  There are some great floorstanding speakers in your budget.  The one I'd look at is the Magnepan 1.6.  Available used under $2,000 and I'ld pair them with pretty much any solid state receiver.  You can always upgrade to a different amp later.

the Outlaw sound very promising

Do you want  a stereo set-up or 5.1 set-up? Personally I think a good stereo set-up is better than any 5.1 set-up.

Tektons are amazing speakers they are great because they don't use crossovers. Regular speakers use a crossover which is a passive circuit in the speaker that separates the low frequencies into the woofer and the highs into the tweeter, the crossovers absorb some of the sound though and they produce a dip in the frequency spectrum at the point they are crossed over and this takes away from the sound. One type of tektons have single driver speakers which use a single "full-range" driver which produces the whole frequency spectrum, the only drawback to this design is that the bass isn't as present as in regular speakers but they have much better clarity and everything  else sounds better especially in the midrange since they don't have that dip  in the midrange like regular speakers with crossovers do and so voices pianos and guitars sound much more real and like they're suppose too. Then tekton has the ob4.5 and ob6.5 speakers which attempt to address the shortcomings of single driver speakers by using to identical drivers wired together but without a crossover, one driver in a bass tuned port and the other is an open baffle, this produces a more full-range sound with a better bass response, so they have all the benefits of single driver speakers without as much of the drawbacks.
