"Splitter" used for Monoblock Operation?

This may be a stupid question, but here goes anyway.

Being completely new to the "High-er End Audio" this is all a little overwhelming, not to mention expensive. Nonetheless, fun and challenging.

I am trying to cable components that were recently purchased, in fact, they are still in boxes. Here is the equipment list:

Pre-amplifier - BAT (Balanced Audio Technologies) VK-52SE
(Which is a balanced tube preamp)

Monoblock Amplifiers - Spectron Musician III Mk 2
(with all available upgrades)

Speakers - Gallo Ref 3.5's

Interconnects -
From what I have read thus far, the best recommendation for connection between the preamp and the amplifiers is to use a balanced cable, since the preamp is balanced. Also, the preferred method of connection is to utilize the XLR connection instead of the RCA connection.

Does the "Audiogon" family agree with this? If not, Why not?

Either way, for a monoblock configuration a "splitter" must be utilized at each amplifier. While looking for cables here in the "Buy" section of Audiogon a search for "Splitter" comes up empty. This is a little confusing. Numerous cables, no "Splitters". Am I using the wrong search term?

Do most of the cable manufacturers make splitters for their cables or should I be looking for one from a different manufacturer?

Lastly, I would also like to hear any comments regarding speaker wire recommendations that would work well with this equipment.

Thanks!!!!!!!
