Integrated amp with 2 pair binding posts

Arcam Alpha 10 has two pairs of binding posts. Sounds great, and can be upgraded with HT signal processing if needed in the future. For more power an Alpha 10P stereo power amp can be added: Quad wiring anyone?

I believe both sets of speakers must be 8 ohm min. Of course, you could connect both sets and only have one set playing at any time(they are switched).

DO you want to play both sets at the same time?

I believe how that works if the posts are simply for biwiring is they are wired in parallel. This would mean the amp would see half of your speakers impedences . For example if you had 2 pairs of 8 ohm speakers the amp would see one 4 ohm speaker. If you had 2 pair of 4 ohm speakers the amp would only see one two ohm speaker. The 8 ohms speakers shouldn't be a problem, but 2 sets of 4 ohm speakers would probably give your amp great difficulty. Make sure you know the wiring of the amp and the speakers impedences before you try this. If the amp has one 8 ohm output and a 4 ohm output, I wouldn't try it at all, unless you can determine that they were wired in series and not parallel.

Thanks for all the info. I probably will not play both speakers at the same time. However, I would like to have the option of being able to play them at the same time ( one set of speakers are on the porch). I would look into amps that would allow the speakers to be switched. The other option would be to buy a speaker switch box (Adcom/Jamo/Niles) and hook one of the pairs of binding post to it. My speakers are 8 ohms and since the speaker switch boxes are wired in series it should not be a problem. I presume that the speakers may require more power to get them to play louder.

My Audiolab 8000A has two sets of posts and I would assume (but don't know for sure) that the 8000S probably has as well. Discontinued because Tag McLaren acquired Audiolab, but there still may be some new units available (at half price!) from Artech Electronics, the distributor. More in line with the price range of the Puccini. Info on the amps is posted on Artech's web site.
