The TU-X1 was the finest tuner Sansui ever made. Very expensive when new and engineered without compromise, the TU-X1 is actually two tuners in one box - an FM tuner and an AM tuner. FM and AM sections have their own separate signal strength and tuning meters, tuining knobs and output level controls. As everyone knows, the AM waveband is not capable of high fidelity sound, but Sansui's engineers nevertheless took AM very seriously indeed when designing this tuner. The TU-X1 has, to my knowledge, the largest integral AM antenna ever fitted to a tuner and the AM section manages an incredible 65dB claimed signal to noise ratio (45dB is more usual for AM) and a 40Hz to 7000 Hz frequency response!
The TU-X1 is a very strong contender for "the finest tuner ever made" award, along with other Japanise supertuners of the era including the Trio (Kenwood overseas) 600T and KT-917, Sansui TU-9900 and TU-919, the Yamaha CT-7000 and others. No modern tuner comes close to the all round ability of the Sansui TU-X1 (Linn, Quad and Naim enthusiasts take note!).
Like all Sansui's amplifiers and tuners manufactured in the late 1970's the TU-X1 has a thick aluminium front panel painted in matt black. It looks very tasteful but the paint finish can be easily chipped/scratched when subjected to careless handling.
The X1 has a legendary reputation and is extremely rare so prices are very high but still reasonable considering it's quality, performance and rarity. If they were to produce the Sansui TU-X1 today I estimate it would retail for somewhere between £4000 and £6000.
