After seriously looking at the Yamaha, I have decide to give Peachtree a try. Just like telescope_trade, the dealer who sold me the LSA's also advised that they are a particulary good match for my speakers because they extend the top end considerably.
In the end, I think I would have been equally happy with the Yamaha but the fact that with the nova I won't have to buy a separate DAC - less money, smaller footprint, more efficient due to class D design.
Also, I was thinking of buying the Oppo 105 in the future, now with a really great DAC built into the nova, I can probably get the Oppo BD-95 and save myself several hundred $$$.
Dealer also mentioned that the built-in DAC significantly improves the sound of internet radio (I use Apple TV for this), so that's another plus as I listen to internet radio quite often.
Will order the unit sometime next week. I hope I won't regret not buying the Yamaha as it has received nothing but rave reviews.
want to thank everyone for the wonderful advice. and telescope_trade, you have a week, if you get bored with your nova just let me know :)
