Okay, so I've been playing these Jamo C 803 speakers for about two weeks, now. They 've been logging at least 5 hours a day. On most days, they've been logging a good 7-8 hours.
I'm going to try and convey how these C803 sound on their own and compared to their little brothers, the C603.
First and foremost, the C803 are very musical, smooth and pleasurable for long listening.
They are a little more polite or laid back than the C603. But we're talking a slight difference there. Nothing earth-shattering.
Much like the C603, these C803 handle low bass frequencies quite well and I have yet been able to make them sweat. They handle everything with poise, coherency, stability and smoothness. Unless the recording is rough, at which point you'll get a presentation that's a little rougher.
Their off-axis dispersion is absolutely amazing!!!
I tried them set up facing straight out and with just a slight toe-in. I mean very slight. One hair's worth. Okay, maybe two hair's worth
Any one in front of these speakers gets a full presentation and moving one's head (or body) to the left or right yields no real differences. So there's no Sweet Spot Exclusivity. But what's even more impressive is how they sound if your literally standing to either side of these speakers. I mean right next to them. The sound is so full and coherent.
More impressive, is the sound in other rooms. Have to run to the kitchen? Bathroom? Pick a room, the sound just travels through out the house and remains very coherent and rather full, all things considered. I've never had any other bookshelf speakers (except the C 603 ) capable of doing that. And the C 803 do it a little better than the C 603.
The C603, when you stand directly to the side of their cabs, sound a little boxy. When I'm in front of them I notice no boxiness. Only positioned directly to their side. The C 603 also excell at dispersion, but the C 803 are just a bit better. No boxiness sound from the C803, no matter where you're located.
Dynamically speaking they are very good with the punch, kick and crescendos. But definitely not the ultimate in slam-to-the-gut dynamics.
Which for my tastes, is perfect.
So far, I really love these C803.
I still love the C603, though. For their price, build and performance. Not to mention their sweet, organic presentation and musicality; it's hard to beat. The C803 are a more expensive bookshelf and the improvements are noticable. But they lack a certain something the C603 bring to the table.
Not really for worse, just a little different.
What's better would be up to each individual's ears, personal preferences and bank account.
