My Onk TX-NR818. Now some who read this may think "Well, that's just an integrated receiver. If you had a real amp you'd tax your 160." I don't think so though. I sit 14' away from my 160 so at 1 Watt in, I am getting 80dB of SPL out. 80dB for me is loud. But let's say I'm feeling particularly feisty because I've had a sarsaparilla so I crank it to an average of 4W. Now I'm getting blasted by 86dB. That for me is a very uncomfortable nominal level. Even so, at 4W, I have another 15dB of headroom for music "transients" before my Onk reaches 64W. At 64W, the regular 160 doesn't even break a sweat because it's rated 250W continuous and 1000W dynamic.
You can see therefore how ridiculously loud one would have to be playing before the regular 160 is taxed or conversely how far away they'd have to be sitting from it. Then of course there's the question of how much better is the HP version which none of us know.
