I hope I can help out, Reload is entirely analog so the a/d is your DAW and the speaker emulation is using the included WOSIII plug-in
The VB-101 and Studio offer multi format digital i/o at all common clock speeds (internally or as slave)
When using the digital out of the Live, a) the Live is clock master, b) the sampling rate must be 48 or 96 kHz
The speaker emulation process is digital so if you use a hardware box, you will be converting to digital. 2 exception, the Reload as mentioned above and the VB-101 which has an analog pre-sim output (unprocessed). In both cases, the WOSIII would provide speaker emulation within the DAW.
Your UA may have 192kHz (not 196) but unless you are doing classical recording using DAD's (or similar) and 1 bit direct to disk recording without edits, in most if not all cases, 96kHz will be the highest you want to go. There's no point getting into this here, on Gearslutz and various other pro audio forums, this has been hashed to death.
The Studio is projected to have a similar price point to the VB-101 but isn't finalized as exchange rates are fluctuating and it's a moot point until the unit ships.
