Jadis JA30 Mk2, how great???

Butler, you are welcome to visit any time.

Gwalt, I am using two preamps : CAT SL1 Legend and Jadis JP200.
Currently, I have the amps driving the 100K Marten Coltrane 3. They just came back from Michael Fremer for the upcoming Axpona. It is the only pair in the US at the moment. JA30 Mk ii control those dual 10 in woofers without any problem whatsoever!

P.S. The cables are Stealth Sakra V12 and Dream V14 with tuning rings.

Kyomi, please also let us know how it performs with rock/blues (does it do justice to guitar/drums/bass based bombast).  Also could you specify how hard the Marten's are to drive......thanks.

Gwalt, yes, my comments are are based on KT150. 

Butler, absolutely! I listened to the whole Dark Side of the Moon (great Japanese pressing) and regardless of it being one of the most difficult records to reproduce correctly, the amps did a spectacular job conveying the sheer scale of the masterpiece. 

Martens are 89db with nominal 6 ohm impedance dropping down to 3.7 ohm ( I suspect it is lower, since I had to change the taps of my old JA50 to 1 ohm setting in order for them to drive the speaker). Even though the speakers are rather sensitive, it is still not easy for the amp to control two 10 inch drivers at 3.7 ohm.
