I didnt realize these are 88 sn sensitivity . I have an amp made with the ICE a1200as2 module which is good for 600 rms x2 but curious what kind of class A/B amp will run good on this amp as I might try another amp.

ive had the Crown XLS amps and my current amp is basicallto ,one them. im thinking a nice high current amp would do the trick

    Those 1200as’s are hard to beat. This might sound crazy but I’m running 2 of them as monoblocks which means they’ll put out 1200 into that 4 ohm load.

    Listening to it now as I type and I did not expect this much improvement.

    Just a thought as those 707’s love power too

    Long story short I’ll keep some AB amps around but with the 1200 monos I am DONE


    You can go a DIY route for the second one and save some cheddar too.

    Rotel RB-1590. 350 W/Ch (8 Ω) 648 W/Ch (4 Ω) has no issues driving them. I read a review in Europe published tests of the amp with the power cord melting current limiting circuit disabled and got insane numbers.

    Since Rotel doesn't list the peak to peak current rating on their site do you know what it is?
