Connecting 6 ohm and 8 ohm speakers to the same receiver (speakers A, B and/or A+B)
I have vintage ADS L-710's that operate at 6 ohms and recently purchased a pair of BIC DV62si that operate at 8 ohms.
I would like to utilize both sets of speakers in a stereo set up on a single receiver.
I have a Luxman R-1040 purchased in 1978 which, other than a cranky right channel, is still going strong. It will drive A or B discretely and has an A+B option for driving four speakers
I also have recently purchased an NAD 7220 which has the option of either 4 or 8 ohm delivery, and a switch for A discretely or A+B.
Any suggestions or warnings concerning either of these receivers and these speakers in the desired scenario?
