Zu Essence upgrade kit - worthwhile?


I'm looking for a little feedback on the upgrade kit offered by Zu for their Essence speakers. Has anyone performed the $750 upgrade?
What differences did you notice in the sound? At the end of the day was it worth doing?

I'm trying to get an idea whether the upgrade is worth the money.

Thanks.

I have EL 34s in my amp and see that Tone1313 is happy with a Cayin A50T with Genelex KT-77 tubes. That interests me. I have been wondering if my Sonic Frontier SFC-1 integrated will be better with KT-77s.

I think am going to go for a 2a3/6b4g or a 300b and I am tending to the 6b4g....tubes are more affordable than either of the other two. A DIY Project later next year? Maybe. I upgraded my curent amp with Alexander caps and it sounds like a different animal. Nearly as good as a SET amp but SETs have a transparence end catch a load of lovely details. Do you favor SETs or PP with the Zu Audio Speakers?

I am a Little worried that a 2ae will be too limiting in terms of the type and volume of Music once can choose. What do you think?
