I was in a similar situation a fews years ago and found great success with a used pair (minty actually) of Proac Tablette 50 signature. detailed, revealing, weighty, natural. Nice. I understand the later Tablette 8 signatures are slightly better for similar money. Nice heavy monitors in a lovely veneer are a nice thing to own.
I partnered them with a Musical Fidelity X-150. Grunty, open and a nice match (Proac are used in the MF factory) so not surprising it was a nice match.Mind you a good Cyrus integrated would be another good option. I reckon on the used market, you'd easily get what you want for £800.
