addition of 2nd pair of speakers

I had a Niles box that I had 4 sets of speakers hooked up to. It degraded the sound. I'm not trying to knock you, but maybe get bigger speakers, or a second system. I use Linn for all of my sources and really like their equipment, but there has to be a better way than a selector box. Happy listening.

Bryston speaker selector boxes. Can get them in two or three or four pair speakers. The two and three pair type also has the feature of a headphone output. Little to no loss in my use. Only gripe would be the speaker ternminals are very close together, best to use banana plugs.

The Bryston selector did not degrade my sound at all. Completely agree about the speaker terminal observation above. Use bananas if possible.

Doesn't the answer lie in the capability of the amplifier as it relates to the specs of all the speakers being driven?

I know Linn products are well received and for good reason, nevertheless, I would recommend reading the manuals for your amp and speakers to determine if the amp has the capability of driving both speaker pairs simultaneously.

Glenfihi and Jax2, did you use the Bryston selector box to run multiple sets of speakers simultaneously or to switch between sets running only one set at a time?

In my case I used the Bryston 2 way selector box to at times run one pair of speakers, at others to run both at same time. As many amps/pre have no headphone output, I used it for headphone use as well. For more info if not found on the Bryston web site, one might check the audio advisor site. The Bryston works well, and seems built to last, with excellent sound quality. As with all such type, they present your amp with the proper load to protect the amp, and drive the speakers properly. Some units have a hi/low power switch, as is the case of the Russound speaker selector box with headphone output I also have. This older unit would seem dated as it uses a barrier strip for the speaker connections. I also believe Parasound makes a speaker selector box.
