At the moment have the Stradivari with LAMM 1,2 and the match is really good.
The Stradivari speakers are just magic, and like Michael Fremer said in the Stereophile review : to fall in love with.
There may be speakers with ´more´ but the moment you listen to Strad´s and enjoy music you are beyond need for ´more´.
The Strad´s need a dominant amplifier with speed and authority. since 93 Db there should be no need for mega watt amplifiers.
About the LAMM hybrid.
I have listened to different LAMM on different speakers, and ik like the tubes better then the hybrids.
the hybrids are just a bit tame in top.
there is a wonderfull involvement with the hybrids, but compared to he very best tube amps they lack transparancy and brilliance in the upper register.
If we compare the hybrid with the bigger Atmasphere it´s like the Atmasphere has another 5 Khz on top brought in.
(i would not choose any OTL on the Strad´s though) they have 2,4 ohm somewhere as lowest impedance.
So the synergy LAMM Stradivari is a very nice one, but i would not actually BUY the LAMM having Strad´s.
the 1,1 would be very interesting.
But think about the BAT VK-150SE as a partner too.
Best amplifier i ever heard was the WAVAC 833 SE with 150 watt´s out of one single tube.
i might as well give one of my kidneys for these amps.
The Stradivari is here to stay.
