Not going to lie, ... one of the most massive stressers with hardware upgrades is the market pressure for me not being able to afford bad choices. I'd had an HK AVR 354 repaired a ways back and it's since been great.
Now I have a different line in on a few manufacturers to get different discounts due to a new contact, but still looking at $800+ for $1500+ AVRs. A few hurdles now are this new HDCP, 4K passthrough, DTS X & Atmos (still don't know where my heads at on those), and wanting to purchase something of superior reliability. Reliability is half the battle for me.
I've been hearing that NAD's new lineup is modular in hardware, meaning not only can you upgrade via firmware, but you could literally swap out a fried HDMI component, or bump it up to a new tech down the line without replacing your whole AVR or requiring extensive repairs.
Is anyone familiar with NAD's current lineup? They've never really entered my mind as an AVR contender before. I always thought of NAD in terms of intermediate and affordable quality separates.
