Aesthetix Rhea and Calypso Tube rolling-what did you do?


Hey all!  been having a blast with the Calypso and Rhea here, both in signature versions.  Have a Stradivari v2 cart fronting that and looking to start rolling some new NOS tubes in both units.  Price really isn't 'too' much of a consideration.  I am happy to experiment and play around some here.  That being said, the list out there goes far and wide, and deep.  Looking to add a bit of warmth but keep the top end as airy as i can here.  The units are a bit dark and seem to roll off the top octaves just so slightly.  Bass isn't bad, not last word of slam and could be improved on probably as well, but far more concerned with midrange and top end dynamics

Would love to hear what the community has done with their units and how you got to your 'sweet spot'.  Thanks!

Thanks for the response.  I have spent a good deal of this weekend crawling the web and it seems the Amperex Bugle Boys may be right up the alley for the 12ax 7 positions.  Now to figure out the 6922, maybe Amperex 7308s?  Maybe telefunken?  Not too expensive, especially when you take into account these can last from 6-10k hours, price 'per hour' is negligible. Been looking at vintage tube services and upscale audio.  There's some other people out there on the 'fringe' or in other countries, and would have little recourse if it's total BS.  These two seem pretty trusty from reviews.  
There's a ton of great info and feedback on those Amperex 12ax7s.  Seemed like a 'safe bet' to start there.  I can see how this becomes an addiction real quick.  I thought I had a problem with Pinot Noirs, betchya that takes a back seat to tube rolling.
Gave Andy a call.  I already have Amperex 7308 green globes in the 6922 position in the Calypso, but pulling the stock Sovteks and going with a pair of 60's Amperex bugle boys.  Looking forward to the see what the change will be.  I'm certain for the better.  Once that's put to bed, might go same way with the Rhea signature as well, Amperex all the way through.  
I went with Andy B over at VTS.  Super stellar guy.  Takes the time, wants to ensure you know what you are getting.  In this current age of commerce Andy is a breath of fresh air.  I cannot recommend him highly enough!  He's got my business for life, and should probably stock up on every tube I can right now and get a lifetime supply in the 'audio drawer'. I ended up with Amperex 60s vintage 12ax7 and 6dj6 tubes and wow, just wow.  Super quiet, wonderful transparency.  I was able to drop the gain on the Rhea one click, after many years, finally aware of what this unit can do.  I am most likely going to send it out for an Eclipse upgrade here at some point.  I think this is finally the sweet spot in regards to the hifi here.  You can't necessarily do better, you can only do different, and that's a great place to be in....
