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.

@vetusto, Within the right applications balanced can have its advantages, but there’s much more to consider. I’m not sure what speakers your trying to drive, or for that matter what your sources are, but perhaps you should sell the Threshold and consider other options?

There is one question I don't understand: Threshold T-2 was designed specifically for T-series amplifiers, and the specification for this preamplifier says that the impedance at the balanced output is 150 ohms. It turns out that the engineers have made two devices incompatible with each other? It doesn't look right…

The 10 to 1 is a minimum guide (but a
 time proven, good one) not a hard rule. With that said these T series products have a few questionable technical attributes for both amps and pres.

found another preamplifier with an output impedance of 68 ohms: Chord CPA 3200.

@unsound , I have the following system now:
Speaker system: Diatone DS-90C (I hunted them for over a year. Won at an auction in Japan.)
Integrated amplifier: Yamaha A2000 (an excellent amplifier, but it does not reach the level of detail to the Hegel amplifier I had before, however, in the low-frequency range Yamaha is a cut above the Hegel).
Sound source: computer (this is temporary, because I recently bought a Teac NT-505 streamer, it is still sailing to me from Japan).
DAC: Teac UD-501 (a good DAC that served me faithfully for a long time until Windows 10 came out, on Windows 10 the drivers from the UD-501 get up very clumsily, which is why it was decided to change it ...)
Second sound source: Micro DD-8 turntable (excellent turntable, which I got in perfect condition, I also won it at an auction in Japan).
Media player: Dune HD Duo 4K (a new media player from this company has already been released, but I’m not in a hurry to change it yet).
So, Teac UD-501 (and in the future Teac NT-505) and Dune HD Duo 4K have balanced outputs. It is for this reason that I want to build a balance system.
