Yeah it helps to put things in perspective - Naim makes some great products and while their service department is certainly more accessible (in the UK) than a huge consumer producer, it’s still going to cost quite a lot for their time. Seems like they’ve set the minimums to keep the department funded and take away any time spent on preparing estimates, going back and forth on prices, etc. I’d rather see a bench fee for diagnosis and actual cost for parts and labour, but alas it’s not up to me.
Beyond all this - I’ve not had a piece of audio kit fail this way before, so that is most disappointing. Guess it’s a bit like owning a luxury car sports car; more things to go wrong, more time in the repair shop.
