The audio spec's look rather mediocre.  I'm sure they'll trick a few people into thinking it is higher-end because of USB3.  
 

Thanks for USB info, from Daniel's response I assume preamps/convertors aren't quite up to the standards they purport them to be.

I have a Presonus 44VSL. I get 7.3ms roundtrip latency at 24bit 48khz 128 samples. The usb3 driver increased the latency and provided nothing other than the fact it would work. I went back to the previous driver.

Thanks for sharing that Clint. Your tracks sound really nice to me. So, PreSonus isn't off my list of possible options.

Many people have pre-amp prefs based on "colour" added by the pre-amp. Valve pres being a good example.
Cheap pres can also colour the sound going through them, but usually in a bad way.
 
The Xmax pre-amps in all PreSonus gear are intended to be as transparent as possible and not colour the sound in either a good or bad way.

If Presonus delivers average noise-floor of -110dB or better... and has rock-solid drivers (ie: 4.9ms round-trip latency at a 64-sample ASIO buffer size/44.1k), I think it'll do well.
If the average noise-floor is somewhere in the -103 to -105dB range, that's certainly less exciting.

Tech Specs
 
They're listing >110db dynamic range for a mic input and >114db for a line input.

They're listing >110db dynamic range for a mic input and >114db for a line input.

 
About average for similarly priced competitors.  Only 112dB on the output.  The converters are rated at 118dB I/O (which I am assuming uses the same 8-channel AKM codec so popular in many devices including RME's UFX) so that tells me they could have put a little more effort into squeezing a few more dB in performance with the analog components and PSU.  
 
I am being rather fussy here.  Anything better than 110dB is certainly acceptable for professional use, especially in a studio environment.

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?

Recommended audio interfaces:

• PreSonus Studio 192 26x32 USB 3.0 Audio Interface
  $899 , November 2015
  

• ZOOM UAC-2 USB 3.0
  $299 , June 2015
  $699 ZOOM UAC-8 USB 3.0 (like PreSonus Studio 192)
  1.8 msec overhead round trip latency
  2.2 msec round trip @ 96 kHz / 32 samples
  
• ZOOM TAC-2R Thunderbolt (More than twice as fast as USB 3.0)
  $320 , December 2014
  1.8 msec overhead round trip latency
  2.2 msec round trip @ 96 kHz / 32 samples
  Latency time in the TAC-2R is just 4.17 msec round trip when operating at a 44.1kHz sampling rate with a 64 sample buffer size.
  

 
USB 3.0 has a much lower latency than USB 2.0
 
The USB 3.0 improves upon communication model and reduces transmission latency by minimizing polling, lowering CPU usage, and allowing devices to transmit data as soon as it is ready.
 
USB 3.0:  1.3-1.8 msec overhead latency......750 iops
USB 2.0:  4-6 msec overhead latency............200 iops

Actually, additional 6ms latency (18ms round-trip latency at 512 samples 44khz) is too much for piano players and also for music producers which have a huge volume of virtual instruments that have dedicated audio effects.

If you assign 256 samples into buffer, you have 6ms output latency at 44khz (256 / 44100 = 0.0058 sec => ~6ms) and therefore you have 12ms latency in output trough USB 2.0 and 7.3ms latency trough USB 3.0!

I can't produce orchestral music or even playing Piano over than 13ms latency. In worst case scenario I need to set buffer to 512 samples due to a large project and this cause to have around 13ms round-trip latency and therefore I strongly recommend that use professional PCIe sound cards such as RME AIO instead of USB 2.0 audio interfaces or going with ZOOM UAC-2R which has ultra low-latency trough USB 3.0.

Please take a look at the PreSonus downloads for their AudioBox VSL interfaces. Not one has been updated since April 2014. And that update wasn't for compatibility fixes for existing customers. My 44VSL is now connected "class compliant" to my Android tablet running the Audio Evolution Mobile DAW. PreSonus may be great innovators, but they do suck at supporting existing products. Problems with the AudioBox VSL series drivers? Peeps beatching all over the online forums? Solution? Release a new product! Hey, everybody. Want a Studio 192? Woo hoo! Have an AudioBox VSL? What? Can't hear you. Hey, want a 192?
 
OK, I quit on that.
 
The Tascam US-16x08 is an excellent USB2 i/f. Once they released their Win10 driver, I was able to go to 64 samples without glitches. The best I could do with the Win7 driver was 256 samples; much higher latency. The new US-20x20 required USB3 to handle the additional throughput (assuming ALL i/o active at the same time).
 
The US-16x08 streets at $299. A bargain for that much i/o. Excellent build quality. Excellent components. Love mine.
