[CQ-Contest] 160/80 preamp

[VE5ZX]

Has anyone had experience comparing with the 
AY Technologies PRE-2 remote powered 1.8-8.0 Mhz preamp filter 
(http://www.aytechnologies.com/Products/PRE2data.htm) 
or the ICE model 135B wideband preamp 
(http://www.iceradioproducts.com/reconly.html)? 

In particular how is the cross modulation performance? 

I need a preamp to a 160/80 long wire.


tnx
