" My only real question is my current receiver is rated at 105w per channel and I'm pretty sure the rega is 50w. Will I notice a significant power drop in my playback?"
I doubt that you will notice much difference due to the specified comparative maximum power output of the amps per se. It only amounts to roughly 3dB. The speaker is rated as suitable for amps rated at 25 - 125 watts. The Brio is rated at 50 watts RMS into 8 Ohms but the Dali is nominaly 6 ohms so the amp may deliver a little more. The Yamaha seems not to be specified in terms of either RMS or impedence so I suspect it actually delivers less than 105W into a 6 or 8 ohm impedence and I suspect that it probably actually delivers less than the Brio, otherwise there would be no need for them to be so shy about it.
So in real life the Brio is possibly the more muscular amp.
Thanks! I had a feeling something like this would have come up, but didn't know where to reference it.
A speaker spec worth finding is the sensitivity. That is usually expressed in Db at 1KHz per 1watt of power at 1 meter of distance. If it is lowish at perhaps 85Db you may want a more powerful amp if it is 88-98+ Db you are fine.
Another critical factor though is how much current they draw as measured by how low the speaker's resistance in Ohms get while playing. Some manufacturers will tell you the min ohm, like my Focals it is 3.8 Ohms.
