Today I was fortunate enough to audition these puppies. After a constant thorough scrutiny for 2 hours with my 535s and the 846s. a back to back comparison. I wasn't awed or disappointed, it's just not GROUNDBREAKING or REVOLUTIONARY. If you ask me if 1000 bucks for these are justify. To me, they're not. The only difference to my ears, the soundstage is slightly spacious and tight. The bass isn't impactful compare with the 535s. They're subtle and distinguishable. bass coming from the 535s, you can hear the thud, thud, thud when it is on which rumbling down in both your eardrums (it's like PS3 dualshock), however with the 846s is just subtle and elegant. The details are bit clearer, a bit more extended with the 846, for example, you can hear the birds chirping in the complicated instrumental background. But with the 535s, you can still heard the chirping, but less extended. the details are clear but not clearer.
So in conclusion, would i be willing to pay double the price just to hear the extended, clearer detailer sound of the birds chirping in Dream Land, track 1: Children. NO!
For 425s owner, the 846s would be a huge jump, but for the 535s owners, the differences are barely noticeable!
Paying premium price for these are the types of folks that wanted to show that they got that kind of moolah to burn. it's to show off their financial status. the sad thing is when the 846s became obsoleted because 959s are coming to replace its predecessor by becoming the successor. the novelty quickly wears off!
P.S I'm happy with my 535s because I know that 99.9 percent out there have crappy audio set up. therefore it makes me feel better.
