Stereo or monoblocks

Monoblocks for the win. 
 

plus, it,makes a statement. You like nice things.

@thbullard3 while I personally run monos on my main system as my primary amps, the next level stereo version amp id want would be too heavy. I also rotate in a secondary stereo amp with lower power and less weight yet it’s a true full Class A amp. So, "it depends". In your case you’ve outlined two scenarios. A few more questions...

While the Tyr amps are nice, and IF I owned a c-2300 preamp, I’d see some value in owning the matching 402 stereo amp understanding the designers voice and match some components to work together nicely. It’s more of a crapshoot with the Tyr more so than the 2300/402 combo. What’s interesting is that MC 402 is 110lbs. Each of the Schiit Tyr amps are 55lbs each, exactly half the weight. Yes, a consideration. My former stereo amp was just under 100lb, not as easy to move. So think about it - how often do you plan to move the amp(s) once in place.

Looking closer at your speakers, seems like either amp(s) would be fine for your JBLs. I wonder if the MC 402 is going to sound a little darker than the Tyr monos.

Do you prefer a darker/richer sound like most MC is known for, or do you prefer a little more detail and transparency you might get out of the Tyr amps?

10yrs down the road, or if you resale again later, its a toss up which will bring better return. How long are you planning to keep the amps, a few years, ten years+, or ?

I have monoblocks though it’s due to sound performance per dollar. There are excellent stereo amps and crappy monoblocks. 
 

If you can audition - I recommend it. 

You can probably get a better stereo amp than monoblocks at the same price. If you compare monoblocks amps to a stereo  amp of the same design and watts per channel then monoblocks will have the better performance, but at a higher price tag.

Most important is the sound of the amplifier once integrated into your system. Pick the one that sounds better. Second, I prefer mono blocks because I believe they have the potential to sound better but more important you can use shorter speaker cables that can be expensive, so the savings there can be put toward the greater cost of the mono blocks.
