Joule Electra LA-150 MK3 vs MK2?

I recently upgraded from the LA-150 MkII to the LA-150ME. The LA-150ME was only briefly available, and has since been replaced by the LA-300. Regardless, the LA-150ME is a clear improvement over the LA-150 MkII, which was already one of the most natural sounding preamps I've ever heard. The sound of the LA-150ME just sounds truer to the ideal of real music. Textural details of acoustic instruments are more detailed and realistic. I'm planning to upgrade my unit to the LA-300, as soon as Jud has the time.

iSanchez, Its interesting how this preamp can enhance what we call "slam", something I previously attributed mainly to the amplification stage. Fortunately this preamp is able to balance it with natural yet detailed sound. No doubt the internal Elrod wiring is important in balancing these qualities.
