I like the LAP150 linestage for its warmish tonality without sounding murky or slow. I also have heard and liked very much their OTL amps. These too are on the warm side, particularly for OTL amps, which still manage to retain much of the genre's advantages in terms of liveliness and dynamics.
The big issue with their gear is longevity and reliability. Both the linestage and the various OTL amps had some issues with build quality and reliability. I happen to be listening to one of their OTL amps at a dealership when the amp delivered a HUGE pop. It turned out that the tube sockets were going bad on the amp and had to be replaced. I found out later that this was somewhat of a common problem with this particular model. While socket replacement in most amps would be time consuming but not extremely so, in an OTL amp such as this particular model, it was not easy to do because it had MANY tube sockets and a whole lot of point to point wiring.
