Opinions about upgrade

Thanks for your replies. My budget is about 4k pound and My room 22x12 feet square. Yes, I like my hegel h160, it is really a good amp. I have no special concern about d18, Indeed i want to better speaker in every aspect. But better soundstage, neutral frequency response are my priorities.

Hello again,

It was not on my list but I see some ATC suggestions, could my hegel h160 drive these 85 db speakers? 

My hegel h160 line outputs have only rca connections, but atc scm 40a has xlr connections. How can i connect these, An adapter is a must? If so, is it a bad type connection? 

Hello again, I auditioned some speakers yesterday. Atc scm 40 passives, atc scm 19 mk2 passives and spendor d7. All of them was being driven by magnum dybalab md 208, 100 wpc into 8 ohms.

Firstly, Atc scm 40 passives, with that power, it was not being driven properly, dealer said that too. But one thing about Atc's is absolutely true, its midrange very good, very real, very lifelike. With spendor d7, i liked their wide soundstages and bass responses especially, it is very detailed speakers. But its midrange was not that good, like atc's. Atc scm 19's bass response is very good although it is small. Its midrange was perfect too. But upper and lower frequencies was not detailed as spendor D7.

I have to admit i have fallen in love with atc mid frequencies.
