I am replacing my 12 year old system (finally!) and looking for some recommendations. Mix of music is lots of pop, jazz, vocals. A bit of classical. Want bookshelf speakers. Here are two systems I have looked at. Which would you rather have? #1 NAD C320BEE integrated amp NAD C521BEE cd player (or maybe the C542?) JMlabs Chorus 707s bookshelf speakers (will be on stands) #2 Yamaha rx496 receiver Boston Acoustics vr-m50 bookshelf speakers Anyone have experience with JMlabs 707s? Should I care that NAD C320BEE is only 50 watts (vs. 75 or more for yamaha)? Are the NAD electronics overkill for speakers in this price range? Any advice would be appreciated. Thanks.
