Pehaps I didn’t explain myself very good so in English there is nothing wrong with the A1 / A2 but if you can get an A85/C1 / C2 for around the same price they would be better sets overall as they sit closer to the flagship models.
Likewise if the A1 and A2 sit in the same price bracket I would always opt for the latest model as it would have been carried over from the previous years next level up model and receieved some software and hardware updates.
