Hi Mikk,
If I was in Perth (I’m in Sydney) I would get in touch with Pierre at Revolution Turntable. They stock ProAc & I received excellent customer service from him when I purchased a second hand amplifier a few months ago. I called the number on the website and got a call back very quickly. Pierre couldn’t have been more helpful and we had a great conversation when the amp arrived. I also happen to have the Response D2s and they are lovely speakers.
Cheers,
Jack
