I use Yamaha HS-8 monitors in my home recording studio which I have for the last 15 years. All I can say is that after Tannoys, Alesis MKII Active and similar (all in price range 500 EUR) I finally found monitors that actually represent the true audio image. Mine mixes are now finally real mixed down tracks, and it is true what people say about these black and white beauties - if it sounds good on these monitors it will sound good on every hi-fi system.
When I was mixing and mastering with my previous monitors - I would always end up with one question: 'How I can not hear mistakes during the sessions, and I hear everything in my car, on my home stereo system etc.
Pros: I was actually aiming for Adams a7's but after reading many reviews (and due to price difference) I settled on Yamaha HS8's, and I think I am sticking to these for a looong time. I have reasonably treated room and after a few months of use, I don't think that I need and sub woofer with these monitors. Great clarity, you can hear every detail in the mix (and fix it) and definitely a joy to listen to.
Cons: After a few days of use, one monitor (which was actually B-stock monitor, the only one I found on Thomann) was making noise after 10 minutes of use. It was annoying, and for 2 weeks I was planing to write a complain to Thomann regarding this. Changed cables, playing with inputs but the noise was still there. But in the meantime a new USB audio interface arrived - Focusrite 6i6 and the noise disappeared. Conclusion: there must have been some sort of compatibility issue with my old E-MU sound card, as from the moment I installed Focusrite - no problems whatsover.
Great product
