Hi guys. Apologies if the info is somewhere already available on the forum, I went through 100s of pages and couldn’t find it:
Assuming I go for a 300 that was serviced and DRd (originally from 2003, serviced and upgraded to DR in 2016), does that service also include the replacement of the end-stage transistors to NA009, or the operation only covered the upgrade of the power supply unit?
End question being: is an upgraded 300 DR equal to an “original” DR, from all perspectives?
On the basis that the service was carried out at the Naim factory, a 300 upgraded to 300DR is the same as one originally made as DR.

Apart from the age of the parts that aren’t swapped during a service (casework, transformer etc.), it should otherwise be the same.
Great, thank you!
