How does your wife feel about thin panels? Here are some speakers I would look at:

Cables should be inexpensive. Here is why:

I would go with an inexpensive CD player. Either that, or use the Oppo 103 as both CD player and preamp, and add a power amp; perhaps:
XPA-200 Stereo Power Amplifier | Emotiva Audio | Emotiva Audio | High-end audio components for audiophiles and videophiles, spanning 2-channel music systems, as well as 5.1 and 7.1 home theaters. Products include multichannel amplifiers, stereo ampli
I know, I am very slightly over budget (because all of that adds up to $3k, and so the shipping and cheap wires and tax on the Maggies will take you about $150 over budget). So instead of that, you could use a pro power amp, such as:
Amazon.com: Crown XLS1500 Power Amplifier: Musical Instruments
In any case, you should go out into the world and audition speakers, of as many types as you can (e.g., ribbon, horn, dome, whatever), of as many different brands as you can stand to audition, with music with which you are familiar, of all types of music to which you listen (making a CDR for this is a good idea), and then select the ones you like best. The speakers will affect the sound more than anything else, so plan on spending more than half of your budget on them.
With my home theater, I had a receiver that retailed for about $600 that I was using with speakers that retail for over $6000. It sounded great (as it should). I decided I wanted more (and newer) features, and so I replaced the receiver with one that retails for about $1700. Unless I engage a feature that affects the sound, it sounds the same as before. The new receiver is capable of putting out about twice as much power as the old one, but the old one would drive my speakers to levels I found painful with crystal clarity, so the extra power, in my case, is useless.
The thing to remember from this is that it is the speakers that matter the most. By far. So put your money into them, and then buy decent other gear to go with it. That is how you will get the best sound for your money. Most people, in my opinion, spend far too much on electronics, and far too little on speakers, if actual sound quality is the goal.
