Is the MIC Pre-Amp in the HORUS/HAPI able to handle the DPA 130V MIC systems?

No, HORUS/HAPI supports 48V MICs.

Are the AD modules available in Line Level only (without the MIC Pre-amplifier)?

No, they are available in Mic or Line (switchable). All Analog Input modules are all switchable (on a per-channel base) between Mic and Line. It is not an option but a feature. 

Does HORUS/HAPI have an AD circuits that differ from the Sphynx II ones? Will I get different sound if I will put the Sphynx II to HORUS/HAPI the digital input and compare? 

Yes, HORUS/HAPI has an entirely re-designed Analog as well as AD conversion circuitry. In terms of "sound quality", Mic/Line and AD will be quite close between the two generations of products (all specs within 1-2 dB of THD+N and noise specs, with HORUS/HAPI being typically better. 

What happens if a MIC signal is split passively to HORUS/HAPI and a Mixer and both generate 48V? Will it blow up?

No, The HORUS/HAPI MIC inputs are designed so that if an external source also provides 48V to the input with the 48V supply of the HORUS/HAPI activated, it will not blowup.

Could we have 48 MIC Pre-Amps channels in one HORUS (6 AD modules)?

Yes, for more than 3AD modules refer to the Redundant/Secondary Power Supply requirements.

Does the HORUS/HAPI AD8 Mic Preamp provide a direct PreAmp output without latency, with parallel recording output for the monitoring operation ? Is there any possibility for this option ? 

...

Is there a difference in audible quality between the Mic and Line input settings of the HORUS/HAPI AD8 / AD8P cards? 

We would not expect that a user would normally experience any audible shift in quality between Line and Mic modes. There are some minor changes in the Frequency response, depending on the gain settings of each, which can be measured. But, those will occur in frequency bands either above 100kHz or below 10Hz, thus way outside the audible range. 
As an addendum to this point, since the Line input must be attenuated to cope with signals coming in at levels above +13dBu, which is what is presented to the AD converter for 0dBFS, this adaptation process uses resistive division, which will in turn slightly higher the noise floor in Line mode due to the thermal resistor noise. Thus, if you can be assured that the Line level signal presented to the analogue inputs will not exceed +13dBu, there is then a very slight advantage in setting the input to Mic mode instead. Similarly, we would not recommend to engage the PAD in Mic mode, if not required, for the very same reason.

I was surprised to see that analogue out from the HORUS/HAPI comes back on analogue input less 6dB. Why? 

Merging made sure that nobody can overdrive its Line inputs (capable of accepting up to + 24 dBu for 0 dBFS) nor overdrive their existing Analogue equipment when connected to HORUS/HAPI Line Outs (+ 18 dBu for 0 dBFS) with Default ex-factory settings.

Does HORUS/HAPI have a DA circuit that differs from the Sphynx-2? Will I get different sound if I will put Sphynx II to HORUS/HAPI digital input and try to compare?
