Which is the best amplifier or the best choise?

I have this equipment. Cd Oppo BDP 95 with Benchmark 1 Dac; Preamp with Pass X1; Keff 205 reference speakers 200 w at 8 homs and Theta Digital Dreadnaught II amp; All wired with Cardas gold reference interconected and electrical. I love Rock and Clasic Music. My room is not so big. I want to change the amp for some better. I want to buy some A class used and I have this options:
A) xa.5 Pass 60 wats monoblocks
B) Halcro Dm38 class AB , 180 wats
C) Mcintosh 501, 500 wats clas A

Which would be the best choice for you and why?

Thank you un advance for your coments.

No, I want to chage the amplifier, I am bored. I think an Halcro is cleaner and more acurated. Maybe I will go for that amp.
