Same watts at 8 and 4 ohms?

I'm in the market for an integrated amp and trying to sort through tech specs. My understanding of the tech aspects of hi-fi gear is limited. Looking for some clarity in regard to watts-per-channel specs.

It is my understanding that wpc at 4 ohms is typically 1.5x -2x the wpc at 8 ohms.

But I'm seeing a number of respectable mid-fi integrateds with the same wpc for both 8 and 4 ohms. The NAD 388 is one and I think this is true for several of the Cambridge Audio units at a similar price point ($1500-$2000).

The NAD features make a point of saying " 4-ohm stable for use with a wide range of speakers". 

Would appreciate any insight to what these specs mean and what 4 ohm stable really means to me. My speakers are 4 ohm speakers.

Thanks,

George

Thanks and happy birthday. So far these speakers have sounded wonderful with several less than ideal component combinations and with my far-from-golden ears I think the Sonos will be fine.

Keep keep in mind that while most of the time amps can cruise by with minimal power demands, but when demands arise, they can be surprisingly exponential. If those demands are not met; it can lead to clipping and potential driver damage.

Respecting your need for a small, attractive integrated that will do the job:

The Parasound you just mentioned, or

60 into 8, 120 into 4.  Respectable, within spec of recommended power for your speakers, esp. if you tend to play at half volume.

I had no idea you could get into ayre at this price point, what a great recommendation.
