Power Amp advice

My existing amps are Rowland concerto pre & 201 power amp. A few years ago, I also bought Mark Levinson 326s pre amp which now, I use this Mark 326s preamp with 201 power amp. Now, I want to upgrade my power amp. Could anyone give me some advice? Current options include, Ayre VXR, Rowland 625, Mark Levinson 532H. I have not tried all these, but, personally, from market comment, Ayre or Rowland are preferred, while, mark 532h's comment is not so good, but it has the advantage that, it comes from the same brand as my current 326s. Thanks
