Hi Simon:
If I remember your system correctly, you were using NAD amplification and listening to a lot of orchestral music. In my main system, I just upgraded from a 85 wpc Musical Fidelity (A3 integrated amp) to a 250 wpc Musical Fidelity (A300 power amp). I still do not play my system very loud (the joys of coop living with many elderly neighbors), but what I like about having more power is that even at lower listening levels, the more powerful amp does not sound strained at all ... very easy sounding. In your case, upgrading from 160 to 250 wpc will fall a bit short of doubling the volume of your system, but depending on your listening levels, the sound may be perceived as less strained and that may be more enjoyable to you.
Regards, Rich
