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.

The NT-505 requires that you define the output - XLR (2 options depending on pins) or RCA.  Did you change that setting on the NT-505 when you connected to RCA?

Yes. When switching to XLR or RCA in the settings of the Teac NT-505, I changed these parameters.

 

NT-505 XLR → Jeff Rowland balanced preamp → Threshold amplifier (RCA input) - there is sound - This connection worries me a lot.

@big_greg , You wrote: "(2 options depending on pins)". Which option should I choose? I have an XLR connection to a Jeff Rowland Capri preamp, and from there to a Threshold T-200 amplifier. I can’t find information anywhere on these two devices, which pin is their phase.

It depends on the Threshold amplifier input circuit design, some amplifier just simply use a spst switch to connect/disconnect RCA input to XLR pin 2.

If that is the case, you need to pull out the XLR connector from the Threshold amplifier input, only connect the tube preamp to the RCA input of Threshold amplifier and switch the input selector to unbalanced and see if there is sound.

Yesterday I managed to make the sound appear.
I don't know what I did, but the preamp worked. I despaired, disconnected the preamplifier from the system, and took it apart. I decided that the Japanese master did not solder any cable, or the cable fell off during transportation. I checked all the cables from the power supply to the lamps, once I even got a shock. :) Apparently, the capacitors were discharged about me. :) But after I moved all the wires and connected the preamplifier, the sound started, but it was very terrible. I left it on all night, I'll check the quality tonight. I will be very upset if the sound does not improve.
