I agree with the Rotel amps & preamp choices since I'm quite familiar with their units. Although I have several different amp/preamp setups including vacuum tubes I still enjoy the clean sound of the Rotel 1590 Mk II series.
To answer your asking question about speakers .....I like the Sonus Faber Sonetto 3's for about $4k . I actually liked the 3's more than the Sonetto 5"s when I listened to them at the dealer some years ago. The 3's have a very nice balance of sound with midrange detail and no sharp high end since I'm sensitive to listener fatigue.
