welcome andy . The nad looks lovely and they are pretty good amps . they have tone controls which i find helpful sometimes , i use a modest arcam a75 in one system and having tone controls helps . never heard of the other one . Nad may be easier to resell when you want to upgrade
ou might slip, you might slide, you might
Stumble and fall by the road side
But don't you ever let nobody drag your spirit down
Remember you're walking up to heaven
Don't let nobody turn you around
… Walk with the rich, walk with the poor
Learn from everyone, that's what life is for
And don't you let nobody drag your spirit down
