Bel Canto C5i Integrated Amp OR McCormack HT 3 Power Amp

My question is :  I have to make a choice.

Which of the above amps is a better choice to use with my AR 9 LS Speakers?

The McCormack sounds good but it is 20 years old.

The Bel sounds good as well. It is 5 years old.

I would appreciate your opinions on which amp you would pick.

Thank you
