There is a chart on this page for USB/Thunderbolt speeds. I was trying to get Thunderbolt 3, but would have to wait for drivers for new motherboard that I have. https://www.asus.com/us/Motherboard-Accessory/ThunderboltEX-3/
I have many Waves plugins as well- how is Dgiggrid utilizing them? How is the latency? When I switched from Presonus to M-Audio Ultra 8r, which I use for now, the latency improved- I thought I had no latency on Presonus, but now I can tell there was some.  

How many inputs do you need?  The Motu AVB series is expandable through ethernet connections.  They had some driver issues last year, but it looks like they are beyond those now.  I am planning on getting one later this year.

FWIW I get stable 2.9ms roundtrip on my RME UCX at 44.1k with minimum buffer settings. That's USB2. I really don't see the point of Thunderbolt at this point unless you have a really large input count, and even then you could consider the UFX+.

Using the new MOTU AVB series with lots of I/O here. 2x 1248 plus ADAT interface (plus if needed also the traveling unit UltraLite). Extremely happy with the options (sound, routing, DSP mixes, networking, etc.). I have virtually all my outboard and synths cabled up and ready to go ... it is like a gigantic console over only 3x 1 rack unit. 
 
The AVB networking is brilliant and works like charm. If you can afford it I would recommend it. Units like the 1248 (or the 16A which you may need) are >1500$ a piece and if you need a lot of I/O you might need 2 or 3 of them. But the system is perfectly scalable, meaning you can buy one now and other later. I actually added the UltraLite lately as it has sufficient I/O for my traveling/live synth rack and when back in the studio all it takes is a single LAN cable to have it all hooked to the studio racks.

Take a look at Antelope Audio. They have several high channel count interfaces. I have the Orion 32+ and love it.

Thank you for all replies. This is new computer and my Presonus Studiolive 24 does not work with it because they did not sign drivers with Windows 10, they may do it one day but nobody knows when or IF they will. Their support is not very helpful. After 3 e-mails they told me, sorry, they can not help me. I called few times, they told me- there is no need to call any more- they will not help. Check back for the driver update that may or may not happen one day.
 
I still strongly considering new Presonus 32 channels board, but the weird thing is they have 16 combo  1/4" and XLR channels, but 16 only XLR, and I don't know if it would accept line input if it unbalanced. And what is with 44.1kHz and 48kHz sample rates? I kind of felt like getting some Class A gear, but not at Protools HD price. Actually Universal Audio is very expansive. I hope their interfaces better than their headphones.
 
I am not Behringer type of person, not that I don't trust it- just not inspiring for me.
 
Just xcalled Asus for my Motherboard and they told me they don't have driver for Thunderbolt card. So I guess if I want Thunderbolt, I would have to wait for their drivers. And while waiting for Thunderbolt, I may as well wait for Presonus. Just saying. This is frustrating.
 
 

Sorry for your problems with Presonus support! To answer your question about the inputs, there are 16 Mic inputs and 16 Mic/Line Inputs. The Mic/Line inputs on the StudioLive can also accept line-level signals. These inputs use TRS-XLR combo jacks that can accept both XLR and balanced or unbalanced 1/4” cables. The ¼-inch TRS connectors bypass the gain stage and are scaled to accept line-level signals up to +18 dBFS.
 
Here is a link to the manual if you want to check the other features:

Why cant I post here?

What is going on with my thread? I posted long reply yesterday, it was there at first, then it disappeared. Then I used Back function, copied it and posted it again, it would not post. Then I typed something to make sure not everything is just copy/paste, and it posted. I saw it there last night. And it disappeared again today! This is strange. Was trying to post it again and it would not post but "Why cant I post" above did posted.
 
hBarton, what are the Mic inputs used for? (Other than mics)? Can it be used for line signal if I had TRS to XLR cable? Otherwise- they would be useless for me. What a waist of real estate! I just watched video on new StduoLive 32. All these features... are nice if you doing live gigs with the band. I just need to connect bunch of hardware keyboards. Currently I have all 24 ports taken (Mic, Guitar and 10 synths/keyboards, plus electronic drum set). I need ONE mic input, not 16. Also I have no use for motorized faders, remore iPad control or onboard effects. I tried their reverb for vocals. It is alright but I would not record vocals with oit. May be compressor could be useful...
 
I am actually thinking- I may end up keeping presonus 24 and use it as a patch bay, running its output in to what ever audio interface I select. It is not ideal, but I don't use hardware that much now days, so for those occasions where I want to record one track from hardware synths, it can go through Presonus in to let's say MOTU... Also In that video they said, "Connect AVB to AVB port on Mac- now all new Macs come with AVB ports". What is AVB port? I thought it was Ethernet-like port that connects in regular Ethernat port on ANY computer.
 
So with MOTU... AVB series: on Windows, I would be using Ethernet port? The 1248 model is Thunderbolt- AVB. Looks like AVB is to connect more than one unit in chain, not to connect to computer? Will still need Thunderbolt (will have to wait for that Thunderbolt card). What 256 inputs and outputs they talking about? (128in, 128out)?
 
Thunderbolt (compatible with 1 and 2) Here is already a problem: I am waiting for Thunderbolt 3 card, when driver for it available, I don't know if it will be compatible with TB 1 and 2.
 
1 x USB 2.0 audio class compliant
      USB 3.0 and iOS compatible
1 x AVB Ethernet (requires OS X Yosemite)- Does it means- AVB will only work on Mac? (It does not say Windows 10).
 
Antelope Audio Orion32 HD 64-channel HDX and USB3 AD/DA Interface

Looks like it supports Windows. Here is Antelope web site. What are those connections- looking like female serial ports- how do you stick TRS in to it? The price is intimidating. $3,500- is it that good? How good can it get? My Ultra 8R sounds relatively good, and it coast $700 back when it was available. how is $3,500 sounds?

Thank you, all.

That worked for me.

You mention the StudioLive is good for live bands but not for your situation. I think that it's a pretty good assessment - it was designed exactly for that. Your patchbay idea isn't so strange. Do you really need that many simultaneous recording channels? Or do you just like the convenience of having everything plugged in?
