Thank you for your great help. Interestingly I already had USB-C port on my motherboard. But ok. I must of still need Thunderbolt.
 
Ok, I think I got everything. Not looking forward to repluggin everything. I am moving from older computer to new, I also need to move drives, reinstall all my synths and effects- what a mass! But thank you again for the consults. I will post back when I start having issues with connecting it all.
Thank you.

Your new setup will work great.
Super low round-trip latency...
 

I would save myself a lot of money, time and grief by going with a Lynx Pci-e 16 AES card.  $700 or so.  A 16 channel Lynx ADDA - new model is about $3500+ and the older models can be had for a lot less.  Plenty of pros used them, and use them, so the quality is fine.  And if you need more ins just add a line mixer for your synths.  The Speck is 32 channels (stereo) inputs, 4 separate outs and runs about $2000 and is as clean as a dog whistle.  In fact, that is probably the best solution to the # of inputs you need - a mixer.  You don't really play 32 synth lines at a time.
 
Sorry to throw out a monkey wrench, but something to consider if you are spending that much.

Yeh a GOOD mixer is a good buy ...especially if it has a way to tie into the PC with proper ports AND DRIVERS FOR DAW USE....
 
That is why I bought the allen and heath r16s...It was suppose to work with sonar x1...but, had issues with motherboard nics, and wi fi, and windows it seemed more so more of issues,...and was not totally working proper with firewire at all...and I got lots of firewire cards of many types tested with TI chipsets....still no joy,  IRQ interruptions plagued the system setup...LSI 400/800 chipset worked best, and they then said that model in their known working firewire choices.
 
So yes, it is all about timing on buying into...FIREWIRE ADAPTER TO TB2 SOLVED, until updates occurred of windows 7...and then odd things with x1,x2,x3, and plat....moving me onwards to new machines..and new os 8.1...nic issues, so I bought a TB 2 audio Motu 828x...x99 and built that...pushed to win 10 to solve internet issues with onboard nic...
Is it supported properly?..TB2 went buggy...and the systems of x99 went down with win 10 screwing it all up!.
 
 
 
And in that, is a crap shoot hit and miss..
 
Sorry but it is true...we all have homework to do, always, if the base is changing...as things could change over night it seems, with one bad update, or something added into the mix causing new conflicts....makes it all futile, if not taking notes of what works, and what does not.
 
Right down to updates being buggy also, and plugins..and this or that for some but not others...and thus bios version, and or drivers/firmware put properly to either fix bugs found, or comply with new update versions of OS..by windows default Driver setup, when installing the os fresh, removing those default win drivers, and getting the proper new drivers from the cd, or manufacturers of said devices, when all is said and done installed without issue, and is working proper with devices not logging any bad issues or driver conflicts, or IRQ sharing beyond reason...(dependant on user and use, I would not share my audio device with anything)....You can then install software to use, that setup.....
 
Once it is all put right...turn off auto updates of anything wanting to do for you, and disconnect from the internet, and turn off internet nic...freeing up another IRQ.
 
And that system should run fine, if no issues of crash, or shutdown is made forced without proper shut down deployment.
 
But Windows still crashes from time to time, and corruption happens, still not sure why things just go that way with computers...So, be mindful to write it all down what you are doing and tweaking , so if it goes down, you might regain some setup, if needs be.
 
So a small note pad for each system, holding key codes and tweaks is a good method to take into accounts.
 
And Back it all up when it is properly working after testing it out for a few weeks of burn in!...try not to add to that much there after of anything new other than wave files or midi...and it should work for a bit of ..time.
 
Getting that is half the battle, and you might be locked into the update path ...never getting any bliss...but if you do....think about what I am saying...if you get that bliss, lock it down and back it up...so no changes occur at all.
 
And you be well, start sharp, keep reading up, and taking notes!...it might help others when you get it proper.
 
 
And you know I am waiting on that ...solved posting wth word and how to!
 
And I might come back to PC and sonar....and I might not..but others might try your solution if so works out.
 
Cheers!

I just called MOTU. Spoke with very knowledgeable and patient representative. He told me that AVB Ethernet will not work on Windows, but Thunderbolt should and that I can connect devices to each other via AVB. The interface will see them as single Thunderbolt or USB 2 (up to 26 inputs) interface.
 
So I can have
MOTU 1248 4 x XLR, 8 x 1/4" TRS, 2 x 1/4" (hi-Z) at $1500
MOTU 16A  16 x 1/4" TRS at $1500, I will need 2 of them, $3000
Total $4500
 
Or, if I go with Antelope Audio, I can have
Antelope Audio Orion32  4 x DB-25 (32 channels) at $3500 (includes plugins and DSP)
Antelope Audio Orion Studio HD 8 x XLR-1/4" combo (mic/line), 4 x XLR-1/4" combo (mic/line/instrument) at $3400
Total $6900
 
Or Universal Audio
Universal Audio Apollo 16 2 x DB-25 (16 inputs) Includes Plugins. Will need 2. At $3000 will be $6000 for 2.
Universal Audio Apollo 8p 8 x XLR-1/4" combo, 2 x 1/4" (Hi-Z) at $3000
That is $9000! That is not what I can afford. Did not realize that AUD is the most expansive.
 
Should I go with MOTU? Thank you.

YOU GO GURL!!!
