I have the kdc-x859 and I love it... Frankly, I don't know what the difference b/t an 859 and a 869 is... I didn't even know kenwood makes an 869, I thought the highest was the 959... Anyway, great unit, great sound quality and very versatile when it comes to sound contouring... I do wish the system EQ layout was a little more user friendly, to change the bass you have to push and hold for 2 seconds which is a little annoying, I find myself just changing the non fader level (controlling my sub which is powered by a RF amp pushing 530W RMS so I have plenty of bass). My old Pioneer had a little better menu layout, but the sound quality of the X859 is amazing. There are things on there that I haven't figured out how to use or what they are... oh, I also got mine at Kenwood's cost, so I was a little pleased with that too... (working for Crutchfield had its added perks)
