Audio Research HD220

Hello to all. My name is Flavio, I live in Italy and I'm a fan of High Fidelity.
Sorry if my English is not perfect.
I wish to ask for advice.
I have a pair of Thiel 1.6 and a preamp Audio Research SP 17.
I want to buy a Final Audio Research HD 220.
Do you know this the end? How does it sound with Thiel?
thanks
