Thanks David, hope you’re well. 
I’m going to try and get the speakers further apart. I’m sitting 11’ away and they’re about 8.5’ apart. Then I’ll try toing in. I’ll report back as I experiment. 
@abd1  Things are slowly moving along. The downed tree is scheduled to be removed on Tuesday. After that the collapsed chimney and major debris from the side of the house will be removed. There is a section on the inside of the house that will need to be sealed for protection from dampness and mold, etc. This is just the start. 
On a very positive note, I have beautiful music. 

There is a gentleman interested in my Pass XA 30.8 amp. I powered it up yesterday and have it playing music via the Nenuphars for about 2 hours now.

Have to say it is holding its own. Very good... in fact quite good!

Scott's new 2A3 amps have 80 hours of playtime on them since being re-powered up (once the electricity was restored, post Ida).  I'll post more about how they are performing, in a day or two.
Sounds like an awful experience but glad it’s just material damage and you’re able to be in the home. 
I’ve never heard a 2a3 tube. I’m using 300b SET monoblocks right now from Sophia Electric. Beautiful mids and highs but I’m not getting the bass I like. I have an Alan Eaton 45amp and I really like the sound it produces. Not quite as refined but the bass is more alive, punchy. Thinking about trying a Primaluna Evo300 amp as I really like my old Dialogue series and love the EL34. Not sure if anyone has tried Primaluna with Nenuphars. 
Alan is building me a set of his 45 mono as well.  Which 45 tube are you using?
