This is my short write up of the Revel Performa3 M105 and I do not claim to have golden ears --- the speakers do need some space from the rear and side walls
Voices and Instruments from octave to octave sound rich and balanced with good layering and texture and extension -- the trumpet and saxophone sound really good together -- piano with both high and low notes are easy to detect -- nuances are clear and easy to hear for both voices and instruments -- cymbals are quick with no overhang, drums have good punch, reverb and depth.
The overall sound is vivid but neutral with no brightness or edginess -- the tweeter is one of the best that I have ever heard. The image is crazy good and the soundstage is full, deep and wide, with good central imaging -- you are drawn into the stage -- there is a good sense of air and space. The timing seems right with these speakers. While these speakers are not so-called lush or warm, you can relax and enjoy the music.
Nora Jones voice which tends to be raspy and grainy, comes across nice with these speakers -- even Willie Nelson sounds better. Jackie Evancho singing Angel, was rich, and brought out more of the fullness of her voice. ..... The bass for the notes that they can hit is tight, articulate, and tuneful -- the rear port is overall clean.
Movies and TV are good with these speakers, with good detail and dynamics, however some speakers can be more dynamic. The speakers can and will play loud, but do not try to blow the roof off. The Revel M105 is better than the Snell K7 which use to list for around $1250 and the Boston VS260 which use to list for around $1400. The Revel is about in the same league as the former MB Quart Vera V05 speakers that listed for around $2000, the Vera has a bigger woofer and more bass, but the bass of the Revel is more tight and articulate.
Those who want to spend some money for a good set of speakers, should put the Revel M105 on a short list. --- I have already had one offer to buy them from me
