@spacebird42 , The CS 1.2’s with their moderate sensitivity and perhaps more importantly above 4 Ohm impedance they are amongst the easier Thiels to power. They can not go very low in bass , play very loud l, aren’t meant for large rooms. So used as intended they aren’t that power hungry. Due to their lack of low bass they can sound a bit tipped up. Avoid amplification that’s on the bright side, has mid-range suck out or is loose in bass. If you can find an old ss conrad-Johnson MF-80 that has been recently re-capped; I think you will be very happy. BTW, used alpha-core MI 2 speaker cables are a relatively inexpensive choice that will work beautifully in such a system.
