preamp and amp to integrated

1991 system, luxman tp 117 preamp, luxman dc 117 multi disc cd player, adcom 535 II amp, powering kef bookshelf speakers in small family room, and 3 rooms with small luxman inwall speakers. Rarely play more than 2 sets of speakers. Preamp has died.  Found a very good deal on a pristine Arcam fmj a18, to replace preamp and amp. The old adcom is 60 watt/channel.  The arcam is 50 watt perchannel.  Will this be enough for this little system?  Thanks.

" Two pair of 8 ohm speakers equals 4 ohms. Adding yet another pair to the same amplifier outputs would lower the impedance ever further and that is typically not advisable."

That's not always correct. The speakers can be wired in series, in which case the exact opposite is true. Not only that, not all "8 ohm" speakers are the same. Some can be harder to drive than others.

mb1audio,

Yes, you "Could" wire them in series, but almost no one would know how to do that. They are going to connect them to the amp/receiver speaker A+B output connectors which will put them in parallel. In my example, I"m just talking about connecting the speaker wires into the amp.
