Putting together a used/new combo system. (Long)

Hi all, 
I know only enough to be dangerous and have always relied on the great people here for guidance, with great results.  I have a really nice system (Ayre, Innuos, Herren, VPI, Quatros) and now I am trying to put together a system for my 20 y/o son.

His original budget was $700.  I didn't tell him that he was crazy, but that I would do what I could and not bankrupt him, but it might be a small Christmas this year. We're currently up to about a bit over double that, which isn't a problem, except that I'd like to not stretch it too much more, as I'm already setting a bad example of stereo purchasing control.  Then again, I blew through that idea with my own setup.LOL

He likes all sorts of music, but most of his taste is rock, hard rock, metal, blues....not a lot of soft vocals. ;-)
 

Here is what I came up with so far. 

Pre-amp: I found a Marantz 3300 for under $600. I'm figuring that this is the base of the system, as I don't think I'll find a pre that is as good as this one for anywhere near this price.  Feel free to give me an alternate idea.  Aside from the good looks and known good sound, I like the benefits of the headphone jack, and some of the controls, which will be good for him to mess with.  He plays guitar and does some sound board stuff for other bands, local venues.

The next is pairing the amp and speaker.  Right now, I'm considering the following amp.  A David Belles 200 Stereo Power Amplifier. It's $300, and currently working.  I'm sure it could use some work, but again, a great "skeleton" of an amp for only $300.  I'll revisit this later in an AMP thread.

If I go with a lower powered amp, I will go with one of the below:
a.)Shiit Aegir, $660 used, not much needs to be said about this.
b.)NAD 2140, $240, This is another "vintage" great amp, that likely needs a work over, but this is another skeleton value piece in my mind.
c.)Other options are the same kind of power level but needing work.  Perhaps a Marantz 140A, or Model 32, but they're not as easy to find, and would be about 3x or 4x, the price of the NAD if I was going to go lower power vintage.

Speakers:
 Current #1 choice is Ascend Acoustics Sierra-1 bookshelf speakers. I picked these because they're bookshelf, they're high quality, and they can handle the load/power if I go with the Belles.

Alternate: Boston Acoustics VR2 Floorstanding,$450 I think they look nice, and are not too big. Good reviews, but my son is leaning towards bookshelves.  I think that's the right way to go for a young person who will be in apartments and moving, etc.

Lower power Alternate....Plan B:  PSB Imagine-B, $400 I like these because they're bookshelves and have great reviews and look great, but they're rated 60W and have an impedance of 6 ohms.  The Belles amp is 160W into 8 ohms, or 260 into 4. 

Thank you for taking the time to read this and offer advice.
Cheers,
Jetson

PS Other gear that will be inherited to this system is an MMF 5.1 TT, Wavelength DAC, cables, etc.
