Vintage SS Versus Modern


I’ve been researching 1970s integrated SS amps lately with the goal of finding a softer, more easy going presentation. I would only buy a fully restored unit. I’m aware the early 70s amps with capacitor-coupled outputs will probably provide this but I have some questions:
1. in general, how do the better *fully restored* 1970s amps sound versus modern ones?
2. what is the "house sound" (if there is one) for each major company (Sansui, Accuphase, Marantz, Kenwood, etc.)
3. is there a significant difference sonically between the cap coupled and direct coupled 1970s amps?
4. for what I’m looking for, which models or brands do you recommend?

I can't think of any solid state amps from that era that I would describe as easy-going.
@greg7,
Look for a Luxman L-10 integrated amp. It drove my JBL L-300’s perfectly back in 1978. It had Sanken output power transistors. It did sound nice.

Consider a SONY TA series V-FET...lovely smooth presentation with the caviat that replacement NOS or used V_FETS are scarce and expensive
