I use 801 s3 with tube amps. They really like high wattage, High current amps that cost big money. Getting those speakers to perform well has cost me a lot but it was worth every penny.
B & W Matrix 801 S3 and tube amplifier
I cannot find an impedance graph for B & W 801 S3.. The manufacturer states min impedance of 4 ohm and recommends amp of at least 50W. I am wondering if a 60W tube amp such as Conrad Johnson MV 60 or Premier 11A would do the job for mostly low level listening in a small-mid size room. Does anybody have experience with similar combination ? Would ss Conrad Johnson amp be a much better match ?
