Monoblock setup inquiry


Hey, 

So I'm somewhat of a newbie, but I've taken the plunge down the rabbit hole and have almost completed my system.  I'm running source(mix of vinyl and tidal)--> DAC/Phono--> Freya+--> Aegir--> Kef R3.  Currently I'm running one Aegir which is slightly underpowered for the R3's, but I have another Aegir on the way and I'm planning to run them as mono blocks. 

I've done quite a bit of research on how to set them up and can't seem to find a straightforward answer.  It seems that there's a couple different methods..Horizontal vs. vertical and bi-amping vs bi wiring.  To be honest I think I'd be ok with the simplest setup.  I'd like to dedicate one amp to Right channel and one to the left, and bi-wire if it will improve performance.  

So I have a couple questions..

1. From Pre-amp to amp do I simply connect 1 single Rca from Right output into R input on the amp to the right channel and same for the left? Or should I use both red and white cables to the Amp for the right and both for amp to left channel as my preamp has 2 RCA outs(a total of 4 connects 2 white 2 red)?
(Ive included a link with pics of amp preamp and speakers for clarity)

2. I understand that If I want to use the amps as simple mono blocks I should connect speaker wires to the top 2 red terminals on each amp and connect to speaker, but I'm wondering will I see any improvement if I chose to bi-wire the speakers? Are these amps even capable of bi-wiring? it seems that the outputs on the amp don't distinguish between HF or LF output? does that matter? 

3. And if I do bi-wire should I use a different set of speaker cables that have good performance with HF and a set that has good performance with LF? or will I still see improvement if I use 4 of the same cables?

Thanks!

From the FAQ section of Schiits website on the Aegir amps.

"Wait. How does the monoblock mode work?
It’s not a mode. It’s just the natural result of driving each channel with one half of a truly balanced signal. That’s why you need a preamp with balanced outputs. And that means REAL balanced outputs, not just XLR connectors. Freya is a truly balanced preamp, for example."
Semantics, really. Instead of having both Single Ended and XLR, it's single ended in stereo and XLR in Mono. When you run an amp in stereo and vertical bi-amp, it is a different mode than Mono, even if mfgr. doesn't discuss it as such with their amp. 
@glaspmart, 
Mono connection information is in page 4 of the manual (Mono Connection heading). but essentially, 1 XLR per amp, connect +speaker to R+ of amp, and -speaker to L+ of amp.
With this, you will not be able to use 2 pairs of wires to bi-amp; and would only be possible to bi-wire.

All the preamp outputs of the Freya+ are active (2 RCAs and XLR) at the same time. You can use the RCAs as your bi-amp source.

Sounds like you are referring to the Vidar. The OP is talking about the Aegir. Totally different amp.

@glaspmart

To use the Aegir as a monoblock, you will need to use XLR connections, just so you know. And BTW, the scuttlebutt is that the Aegir loses some of it's magic when bridged mono. Proceed with caution.

I had a Freya and it was definitely quieter Balanced vs SE.  I also felt it was more dynamic.  Get some good XLR cables.  Keep it simple, forget the bi-wiring at this time and just enjoy.
