Category talk:Multiroom Amplifier

What, pray tell, is a multi-room amplifier?

If I see it correctly, the only device registered is a combination of a multi-channel amplifier/mixer with a 6-disc CD changer and an AM/FM tuner!

However, I'm missing a suitable category for this - should we introduce a category Combination Devices' into which we could then also integrate, for example, the categories CD Player/MD Deck_Combination, CD Player/Preamplifier and Preamplifier Tuner?
