I don't think going to 10.5 will add the much of an improvement. I'll expalin. I have an Aries I, with a 10.5 arm, clearaudio Victory H. Early this year I purchased another Aries with 12.0 arm, Benz MC 2. I fed the 12 into the same parts of my system. The 10.5 still sounded better. If you want to get real improvement best to go to the HRX, 12.7 arm, super platter. SDS is always a must.
