sansui 2000a 35 wpc 8ohms and kef c80 4ohm

I have a 2000x in a smaller system.  You won’t have any issues driving the speakers, especially if the Sansui has been well maintained.  Nice preamp section on theses old Sansui receivers.  I used mine as a preamp/tuner for a while as it has preamp out.

Older Sansui solids state is about as close as you can come to the tube sound without actually having tubes.  

Enjoy.

I have a modified set of Definitive BP-10’s, which are 3 ohms. I used a 2000x (no you can’t get rock concert volume) for about six months when I was having gear cleaned and serviced.  It performed beautifully, and was completely stock and had never been serviced.  

Most listening sessions are under 15 watts per channel.  The 2000a should be fine.  The above advice is excellent, make sure the unit can breathe.  

It it is a great little receiver... just be careful with it..
