I was wondering if anyone could provide any help or advice in choosing a receiver to power 6ohm speakers. The speakers in question are: Monitor Audio B4 Front L/R nominal 6ohm 91db Monitor Audio Bronze Center nominal 8ohm 91db Monitor Audio B2 Surrounds nominal 6ohm 90db The speakers have pretty good sensitivity ratings but the 6ohm thing is throwing me off. I currently have a HK AVR 225 but it only mentions 8 ohm speakers on the back and in the manual. I am finding it hard to determine what receiver would be a good match due to most brands rating their receivers at 8 ohms. It's also hard to tell a receivers true power output due to deceptive marketing. If the HK is insufficient, a couple of receivers I am looking at are the NAD T742 or the Denon 1804. Any help would be greatly appreciated. Thanks.
