Before you begin compile any list you should ensure that every pre on it is capable of driving that input impedance to full effect. This will probably weed out 90% of the market for starters.
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.

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

Just for your information, Threshold T-200 (1994-98) was designed by Swedish engineer Michael Bladelius. At the time Michael was working in Threshold, the company underwent ownership changes and sold to Dynatech in 1988, and Nelson Pass left it in 1992. Mike Bladelius became the head of the design office at that time. Threshold T-200 specification: Output power: 100W into 8 ohms (20dBW), 200W into 4 ohms (20dBW), 350W into 2 ohms (19.4dBW). Full power bandwidth: DC–80kHz, +0/–3dB. Distortion: <0.1%; typically <0.02%. Voltage gain: 27.4dB balanced, 28dB unbalanced. Input sensitivity: 1.21V balanced, 1.13V unbalanced to produce 100W into 8 ohms. Input impedance: 50k ohms unbalanced, 2k ohms balanced. Current consumption: 2A, idle; up to 12A full output in mono. |

Most likely the first one, because the second one costs much higher than my budget, and the seller does not want to give up in price, therefore, if I don’t persuade, then in 1-2 days I will buy Pass Labs X2.5 in Japan. |
Part of the expense that went into that Pass pre was for it's balanced circuitry, which won't be a good match into your Threshold amp.
