Joule LA150MK2 upgrade to LA150SE- Any comments?

They are quite similar, unlike the differences between MKI and MKII, I think the bulk of the differences is considerably upgraded capacitors. They are cut from the same cloth so I don't think you will feel you have lost anything. The most noticeable improvement is in improved performance in the bass. Is it it better? I think so, but the MKII is no chopped liver either.

Thanks!!!! "They are cut from the same cloth"....."The most noticeable improvement is in improved performance in the bass" both pretty much what I was concerned about!!! Thanks for taking the time!!

Sam, it is a further refinement, not a wholesale change, so you should be ok if you choose to get the upgrade, both are great preamps either way:)

I'm hoping the upgrade to the SE will give me more air and treble. The Mk2 provides more than enough bass note for my ears. I was hoping the Z-caps will provide a bit more sparkle in the high end.

The Joule site describes the sound of the LA150SE as "The bass performance of the preamp is very strong and solid and the treble is open and airy with great extension."
