Hi, this is my first time here, also, I am buying my first "serious" audio ...I decided to buy Denon AVR-1905, and for the start, since stereo is more important to me than HT, I decided to buy front speakers..Later, with this Denon I will be able to upgrade the system to HT. Now, please, since I have no experiance, help me choose between KEF CODA 90, MONITOR AUDIO BRONZE B4, JAMO E-670 or INFINITY PRIMA 250 speakers. What are advantages or disadvantages with those speakers? Mainly I listen R`N`R and POP music. Is there some other speaker with similar price like those I mentioned. Also, Denon has 8ohms impedance and some of mentioned speaker have 6ohms (MA and JAMO) - is this a problem and if it is what should I do?
