Threshold T-200. Help me choose a preamplifier

Good day, Colleagues!
Not so long ago, at an auction in Japan, I accidentally won the Threshold T-200 amplifier. I really wanted this brand, but I was looking for the T-800D model. But it turned out to buy this amplifier ... And now I am very tormented with the choice.
I spent two days on the internet looking for balanced amplifiers. Here is a list, is there anything on this list worth seeing?
Pass Labs X1 - 
This preamplifier is sold in Russia at a very good price, it seems to me. 1800 dollars. But I do not know his condition. The photographs show that the cable that connects the power supply and the preamplifier itself is frayed. And the power supply is not complete, but a small black box.
Pass Labs X2.5 - I found this preamp for 2000 euros in Croatia, but shipping will cost around 500 euros, so it is already very expensive for me. 
Black Ice F-360 - A very interesting preamplifier. The ad suggests that this preamp has very high detail and can expand the scene. :) But I don't believe in advertisements.
Leema Acoustics Pyxis ll -  This amplifier is quite expensive, I found it in my country for $ 2500 and this is a showcase sample. It has an impressive range of features, there is a phono stage, which I also need, and balanced inputs and outputs.

McIntosh C2200 - But this is already very dear to me.

I really look forward to your help and advice in choosing.

HOORAY!!! Finally, my long-awaited amplifier has arrived !!!!! I’m so happy! I haven’t connected it yet. It is cold in Russia now, and the amplifier arrived very cold. Let it stay for a day. But my hands are already itching to connect! :)

Now I’m looking at it, reading the back of the amplifier and I have questions. How can I connect it to the speaker system?
I have a Diatone DS-90C acoustic system, this speaker system has the ability to connect via the Bi-wiring system. I have a Kimber 12 cable. On the acoustics side, I divided this cable into 4 parts and connect it to the acoustic system using the biwiring system. But on the amplifier side, I divided this cable into only two parts, because in my old amplifier, although it also has the ability to connect two speaker systems, but not through the biwiring system.
This amplifier also has four pairs of terminals. But there is also the inscription "bi-wiring". That is why I had a question. Regardless of any inscriptions, simply plug the existing two halves of the cable into the terminals (but then the question is: into which ones? those that are closer to the center of the amplifier, or those that are closer to the edges of the amplifier?). Or should I split the end of the cable that should connect to the amplifier into four pieces and connect to all four terminals on each side?

By the way, both preamplifiers came to me a month ago. And I still haven't unpacked them. :) Tomorrow I will have a holiday comparable to Christmas or a birthday. :)

Friends, I am facing the following problem: As you know, I bought one balanced Jaff Rowland Capri preamplifier, the second preamplifier is a homemade Japanese tube preamplifier. The switching is as follows: from the Teac NT-505 via an XLR cable to the Jeff Rowland preamp, from the preamp via an XLR cable to the Threshold Amplifier. Further. From NT-505 via RCA cable to homemade tube preamp, from tube preamp via RCA cable to Threshold Amplifier. Checking connections: turned on the XLR on the NT-505, on the Threshold amplifier, the switches are in the XLR position. Everything plays great. I turned on RCA on the NT-505, on the Threshold amplifier I switched the toggle switches to the RCA position. Does not play.

At first I thought the tube amp was the problem. He’s new. I did not disassemble it, perhaps something was messed up with the switching. 
Then I did the following: I turned on the NT-505 so that the sound went through the XLR output, and on the Threshold amplifier I turned on the toggle switches in the RCA position. And you will not believe, the sound appeared .... I do not understand what is happening. Amplifier broken?
It turns out like this: the signal goes from the DAC via an XLR cable to the Jeff Rowland preamplifier, from the preamp via an XLR cable to the Threshold amplifier, but at the same time, the toggle switches on the Threshold amplifier are switched to the RCA position, i.e. signal reception should be RCA, but the sound still goes. I don’t understand what’s going on and how do I get the sound to only go over the RCA cable through the tube amp....

Does your Threshold amp require xlr shorting pins when running the amp single ended?
