I have the PM7200 new model, from them, and i strongly reco it, instead of going back in time...after owning several vintage amps, some Pioneer, Sansui, Technics, Marantz, etc...trust me that the old integrates are not any better than the good modern ones. The level of refinement that you can get nowadays on this new models from them, and from other respected brands, will never be achieved by those vintage receivers, some of them and mainly all of them are not even Class-A...that is another myth to debunk...the only thing that would be different is the price, if you can get one for a good price...
Also keep in mind that if you get one of those, by now, the filters will be dead or about to die, so you may need to upgrade and repair the PSU and mainly all internal caps, let alone some lamps, pots, switches, etc...
Even the heapdhone jack on my 7200 is completelly quiet, very good, the phono stage is decent, and integrated (no need ot go external) unfortunatelly it was discontinued last year, so if you can grab one, hurry up!!!
