The problem with the 150wpc VAC 300.1 and the 90dB sensitive Aerial 9 speakers becomes running out of power during dynamic peaks *if* you listen at levels that approach live.
For example, the VAC 300.1 will run out of steam at about 111dB peaks (measured 1 meter from the drivers).
So, if you listen at around 84dB measured from your listen seat, then you will have enough power for 105dB peaks.
Use this as a guide and determine if it will be sufficient based on your room and listening preferences.
I have a small to medium sized room and I listen at about 8 feet from the drivers. I often listen at nominal levels above 90dB, so the VAC 300.1 with Aerial 9 speakers may not quite get the job done to suit me.
