I have owned the 402au and the 402au and 401hr.
Resale value of 401hr-close to what I paid for it w/o advertising.
Heat and reliability- no problems. The 402au arrived with one channel dead. A wire had come loose in transit. A call to George and I was told to reconnect the wire. I plugged it in and no problems since.
Yes the 401hr ran hot. the 402au solved that problem. I don't know how. I don't suspect the heat is a problem in the 401hr. The heat is generated by the mosfets that are mounted directly on the heat sinks outside the other components.
Circuit layout-Always a judgement call. I like the fact that my amp sits neatly in my cabinet. See speedfreak on virtual systems. The trend is to minimize the footprint
My speaker is the ML CLS. A much more challenging load than your speaker. No problems.
Like TVAD I can't ell you which way to go. Obviously you know what my choice would be. If you like solid state PASS is one of the best. A little too smooth for my taste. The Moscode just sounds more like music to me.
