I used to have a set of KEF Q1s powered by a Denon 3803 reciever, sounded fantastic.
Those KEF Q1's are great monitors in my opinion, they reach pretty low too, subwoofer might still be needed, depends on how much bass you want.
I Origionally bought them as "GET BY" speakers, then once they broke in, speaker replacement became less and less of an issue to me.
The Q1s are great. If you can find a place that you can audition them, you really oughtta do it. The Q1s do a good job of reminding you that you dont have to pay ALOT of money to get good sound.
