If the qs is too expensive and you do not require the features and quality (MADI, AES, ..)
then you could also consider this one:

As I personally wanted to have a reserve of mic preamps I took the XTC which can also be used for AD conversion.

As far as I understand you could also connect 8 analog lines symmetrically via TRS-XLR cable (*)
The 8 TRS inputs 4 are servosymmetric and 4 to be used for instrument in.
And you would have MADI still as an option.
Can be remote controller via MIDI.
4 AES IN/OUT and ADAT for format conversion.
The only device which can be integrated as AUX device into TM FX and fully save the settings in one TM FX instance.
So a combination of i.e. UFX+ and XTC is quite powerful and flexible to be used.
And scales up to 8 Octamics via MADI.
Latency compensation automatically by the devices.
(*) I use the XLR Inputs currently only for Mics, always forget whether these analog INs
can also be used as analog INs, not only for Mics with i.e. TRS->XLR cable.
