Roughly speaking, a 100W/ch amp will play 5dB louder than a 30W amp, unless the smaller amp has extraordinary peak capabilities. It's also.likely the larger amp.will be more comfortable with complex low impedance speakers. As far as upgrades go, the new KEF Q7 Meta is a lot of value for $2k a pair. The Monitor Audio Silver 300 7G are a bit more, $26-2800, but are a step up in overall quality, especially the cabinets. These are two clear leaders in this price range, but you may find others from Revel or the Polk Reserve line to your liking. These are are middle/middle speakers: middle speaker from the middle tier of these very high quality and well known brands.
Need help matching speakers with amplifer
I have a pair of Boston Acoustic Vr-20 floorstanding speakers. Im not sure what the RMS continous power rating of these speakers are in order to make the best match with an amplifier. In Hi-Fi Engine the spec’s just say recommended Amplifier 15-200 watts at 8ohms. is this saying the continous is 15 and the peak is 200. I would think the continous would have to be more than 15 watts being these are larger floor standing speakers. Thanks for help from the community!!
