Aries Cerat Helena or Mola Mola Tambaqui?

I've compared both in the same all Aries-Cerat system (I owned the Tambaqui previously).  They are both fantastic- the AC Helene is more open on top with wonderful organic tonality.  The Tambaqui counters with incredible purity; S/N ratio off the charts, and detail without stridency- both have wonderful staging, but the Helen puts you in the studio even more.  I wouldn't hesitate to own the Tambaqui again, but that being said, Aries-Cerat is the next level, but we are talking completely different price points here...  The end-game goal is the AC Kassandra II- 'one ring to rule them all'...  

At the end I have bought Tambaqui, but if i get some more money laying around I will purchase Kassandra as well :) 

Hahaha totally agreed! My end game dac is a Kassandra II (when I have alot more $$ :p) Just watching youtube vids already enough to send me drooling to the moon :p Sometimes we end up wondering what good hifi should sound like, and I think something the Kassandra produces is what I would aspire to :)

The thing is, I am going from Tambaqui to tube single ended 80w monoblocks SE-833 and I think it had a great synergy this way..... going with great cables Kimber KS 1036 and KS 3038 bring so much resolution and natural and precise sound with so much air and 3d that I can not imagine to get more of that with tube dac.... but who knows
