I've had phenomenal success with the SSB preamps over the last 25 years. 
I have one for both 2 meters and 70 cm and if I had anything worth 
mentioning on 6 meters for an antenna I would have one there as well.  
Prior to that I used Landwehr.

For my EME station I am using a DB6NT receive-only, only because at the 
time the Deutschemark ( or Euro ) was cheap and I could get the DB6NT 
cheaper shipped from Germany than I could get an equivalent SSB receive 
only here. I have no regrets, the DB6NT is a thing of beauty as only 
German workmanship can make.

I see that ARR is now making an rf-switched preamp that handles some 
power now too, but I'd stick with the SSB if I were you, only because 
they will handle up to 700 watts if you sequence them; 200 RF-sensed.

It seems that with the particular preamp and xcvr I have a sequencer is needed to ensure dx is removed from the coax before rf is introduced. I think the easiest solution is to get a different preamp once I get my icom repaired. I could also swap it with the mirage I'm using at home with the 847 which I think is immune to rf or is switched. Unless you have an icom xcvr their preamps are a bad purchase.
