For what is worth, *product review*  I have now had about a week to get used to them & mix some new projects on them.  Tonight I exported some stuff and hopped in my truck for a listen.  If was so freaking happy when my mix sounded identical in my vehicle (Eq set flat) as it did on my monitors!  If it were possible to jump up and down while sitting in a truck I would have been doing it!   I have never experienced a perfect translation like that before and the only thing I changed are the monitors.   Damn nice product in my opinion!  Flat, true reference of what you are working with.  I can't imagine needing to get another set. Ever.? 
*Your results may vary, but this is one happy mix engineer!

I'm thinking of upgrading my BX8's and these definitely sound like a good option.

Yeah - awesome Chuck!
 
I wanted a pair of them when I was deciding on a set of studio monitors but went for the Event ASP 6's for my own reasons at the time - but was really impressed with the Yami's.
 
Good for you Bud! Glad you like them.

I just bought a pair for $300 out of a studio that is upgrading.  At $300 I figured I couldn't go wrong and could sell them if I don't like 'em, but I already have monitors with white speakers ;-)

Do you have a pair of the NS 10's?   I wonder how they would compare side by side in an A/B test.

the ns10s sound nasty.
 
and if you can mix well on them, you are a rock star

I've used the NS10 and didn't really like them.  I didn't find them particularly flat either, but lacking low end.  One studio I was mixing in, that was their main speakers, and it was horrid.  This was a "b' level studio just outside of Nashville.  I believe the newer generation Yamahas are much better, with this latest HS series even being the best.  I've heard these particular HS8 speakers I'm getting, but I wasn't familiar with the music, so I didn't know really what they were doing.  But the reviews on the HS8 seem to be much better than the HS80 and I honestly haven't found anything said negative about them.  They roll off a 37hz... a little lower than 42 of the HS80 I believe. Appears lots of people really like them and they're the best <$1000 preferred by many. 
 
Back to the NS10...  I have a pair of the original Auratones, and I actually like them.  At very low volume, you seem to be able to still hear everything in the mix and it still seems relatively balanced.  I kind of think the NS10 got put on the "bandwagon"....almost like ProTools is now....especially since we all know Sonar is much better!!

oh...btw, my other "white" speakers are JBL 4311wdx, that I've had for a loooooong time and know them well.  They're 3 way with 12" woofers and a little bump in the vocal range.  Other than being "dated" , older style speakers, I really like them.  I'm thinking the Yammies will be a nice compliment, and I'm going to put them fairly close to me and really push the "nearfield" concept.  My JBL's are almost midfield ...and I have them (and me) in about a 8ft triangle.
Here's one of my more "colorful" mixes !! ;-)

Nice.  I like the Hs8's a lot.  I have been working with them for 2-3 months now.     Nice set up you have there bro!

ChuckC - thanks for the posts on this.i'm presently collecting my pennies week by week to finally get some good monitors.

I'm seriously leaning toward KRK VXTs, but reading your post continues to keep my mind open about worthy other monitors I should research.
