[steveB]

Hi Guys ,
I need some advice as to what is best .
I want to add another amp to my RSX1065 to run some B&W604S3's

Do I :
1.get RB 1080 and biwire the 604's(200w per speaker)
2.get RMB1075 and biamp the 604's (2x120w per speaker and leaves one channel spare for future 6.1)
3. save the $$$ coz i wont notice the difference

Thanks

SteveB.

I know that the RB1080 sounds quite different than the RB1070, however I never compared the RB1080 with the RMB1075. I suspect the RB1080 is better suited for stereo performance.

I am using a RB1070 for my B&W 604s3 fronts and the RMB1075 for the centre and surrounds. I plan to ever upgrade to the RB1090 for my fronts and upgrade the fronts to Nautilus series. Then the 604's become rears and will be bi-amped (since I will also go back to 5.1 iso my curreny 7.1).

If I where you I would take the 1080, if you really want sound improvement. Bi-amping with a 1075 wont give you much. Also getting two 1070's and putting them on bridged mono to power the two 604 is not recommended usually. Its usually better to go for the higher model right away.
