Good bass, especially for a bookshelf. Clear and accurate, especially on the highs.

Maybe a little too bright. Maybe even a little strong on midrange, too. Not so much that it isn't easily corrected with the preamp.

I am truly impressed by the Cobalt 806S. I'm playing them on an Adcom GFA-535 amp and a GFP-555 preamp. At the moment, listening to vinyl on a Gemini professional turntable and also CD's on a Pioneer PDR-509. It's a DJ turntable, but it sounds good to me.

What impresses me about the 806S speakers is the clarity. I'm hearing things in the music I couldn't hear with my old bookshelf speakers (JBL S38), which are being demoted to another room. There is wear on my Wynton Marsalis trumpet concertos vinyl record that I didn't know was there. That record is going to have to be demoted to the room where the JBL speakers are going.

The 806S speakers are fairly efficient and a little bright...ok...a lot bright. I'm accustomed to leaving the tone controls on my preamp in the bypass mode. For some of my music, I think I'll need to have the treble down. I usually expect a shortage of bass with bookshelf speakers and have usually supplemented them with a subwoofer. These speakers don't really need it. I played my old Sade vinyl records and got good, tight bass.

Imaging on these speakers is impressive, too. That sensation of having the musicians in the room with you came through very nicely on the Wynton Marsalis record and also on a Diana Krall CD. The CD defintely needed a treble reduction.

Another thing to add, just to be sure what I was hearing, I put every pair of speakers in my house under the same conditions as these and gave them a comparison listen. The JBL S38's are a little dull by comparison but have a smooth, musical quality. A similar but smaller model of JBL's gave similar results. A pair of Polks have limited range by comparison. A pair of Bostons similar to the Polks but not as severe a limitation.

That said...I think these speakers are just right for what I'm doing with them now...running two speakers without a sub and without surround or center speakers. They don't need abundant power and at 75W aren't rated for much. If you're a music aficionado...a fan of classical, jazz or whatever music that benefits from clarity, presence and range...these are great. If you're rocker...more inclined to crank up Van Halen than relax to a little Beethoven, I'm not sure if these are your solution. But if you want to feel like you've got the best seat in the house, maybe these are the ticket.
