How does one decide this was my first thought. Then I thought which integrated amps had a significant impact and the original Nait did, it wasn't the first integrated or the best but it introduced many people to the British interpretation of what a good hi-fi amp needed building on the pathfinding the NAD 3020 undertook before. These weren't the only fabulous affordable integrated of their era. Rightly or wrongly, they had a more significant impact than many of the contemporary integrated amps I believe. Whilst I never owned one, I thought the Onix OA21 was a fabulous integrated and if I hadn't already got a 42/110 would have seriously considered it.
