I just saw this on FB and am wondering how usb 3 will impact latency. I don't see a price yet, but there are several pages of info on their site.

Is this big news? The usb3 part?
Michael

The Presonus USB-2 units (AudioBox VSL) offer total round-trip latency of 4.9ms at a 64-sample ASIO buffer size/44.1k.  
 
RME units... and new MOTU AVB units (connected via USB) also yield 4.9ms total round-trip latency at 44.1k.  
 
At 44.1k, 4.9ms total round-trip latency seems to be the "brick wall".
 
The Studio 192 is nowhere close to saturating the bandwidth of USB2... so I don't think you'll see a major latency performance difference simply by increasing bandwidth.
 
Using a car as an example:  If you car tops out at 120-MPH, it doesn't matter if you put that car on a two-lane road... or a 6-lane freeway (more bandwidth).  The car will only go 120-MPH.
 
 

Some nice features in this new Presonus Studio-192

Thank you, Jim. Good analogy. I certainly wouldn't complain at 4.9 msec! I have to find out if my Tascam us1641's new drivers will help me. I reset it to the lowest latency, giving me 12 msec at 44.1, but have to test out if I can record without issues, first.
 
My local shop carries PreSonus, so I hope to check this one out! I know you have recommended the 1818vsl, and now I have been checking out the MOTU Ultralite AVB, too. So thanks for all your input(s)! LOL

$1200 list price (I'm guessing it'll street right about $1000).
That's not bad at all... considering the quality converters and many features.
If the drivers are rock-solid and deliver low round-trip latency, it'll be a formidable choice.

The MOTU AVB series is very nice too
 
It's good to see numerous (new) quality options for audio interfaces.
Quality converters, low round-trip latency, and reasonable cost...
 
 

A friend on Scott Garrigus' DigiFreq forum, mentioned the PreSonus was going to street at $899, though I don't know where he saw that.
    Yeah, the range of choices seems really good right now, with the Tascam us16X08, the Arturia Audio Fuse, the MOTU AVB and now this PreSonus Studio 192. I look forward to sorting out which one will work best for me.

I was looking at the 192 also, I wanted to post a question for comments more so on the reputation/quality of their preamps and convertors, Jim mentions there pretty good? The car speed analogy helps understand possible significance of USB 3 over USB 2, to keep with that, would that also apply if you had many cars (channels) trying to drive on the same 2 lanes, or would having the six lanes available then be of any benefit? (i.e., is there a point at which USB 3 for any reason would be a significant advantage over USB 2?)

using your analogy built on Jim's analogy, USB2 can theoretically handle about 400 lanes with one car per lane.  USB3 won't become significant until you exceed that many channels being recorded simultaneously.  (that's assuming 44.1kHz sampling rate at 24bit recording, mono tracks being recorded and even a little "overhead" for the physical devices to be able to use).
 
however, your "many cars behind each other" don't apply to the analogy - you're trying to add dimensions to Jim's analogy that don't apply.  in this type of analogy, any car behind the lead car would be your next recordings. :-)
 
Math:  44100 samples/sec * 24 bits = 1,058,400 bits/sec
USB2's speed is 480Mbits/sec (480,000,000bits/sec)
so 480Mbits/sec divided by 1.0584Mbits/sec = 453.515 tracks simultaneously recorded on USB2 theoretically.  subtract about 53+ for "overhead" and you can still theoretically get 400 mono tracks recorded simultaneously.
 
USB3 speeds/bandwidth are not significant yet for recording.

The bigger news for PreSonus, is they designed a device that will work with USB 3.0.  A big problem for the AudioBox 1818VSL users, is they ran into a huge compatibility issue with Intel branded USB 3.0 chipsets.  It took them over a year to come out with a driver to fix the issue.  This was a huge problem for a lot of users as many laptops, and all in one PC's started putting all USB 3.0 ports on their machines.  But essentially for over a calendar year I had a $500 brick in my studio for an Audio interface.
 
I do like PreSonus' innovation in bringing a lot of pro features in a budget friendly price range.  Although Behringer with the X32 line and now the Xair mixers, are giving them a run for their money.
 
I like the specs on this products, although I am disappointed they went to the 2 inputs in front 4 in back design.  I prefer having them all on the front as the 1818vsl did, it's just cleaner for cable management.  But putting the DSP onboard (on the VSL it used your CPU to run the DSP), and their user interface is very simple and quick to use, although I hope they offer a full screen view for Windows.  That was one of the annoyances I had with their Fat Channel mixer, but you can also use the free iPad/iPhone app.
