Nice, glad to hear consistent reports for Alan's amp.  I did asked Alan to remove the volume control in my copy, hoping to gain a little resolution there.  Sorry didn't mean to dis the RCA 45, all my impressions were with Woo WA5 and headphones.  Looks like in Alan circuit they sound great, a good sign for a great designed amp.
no worries on the RCA, they are a little more bland, but in a good way. 
Definitely shoot us your impressions. I adore my little amp!
The fallen tree has been removed (mostly). The stump and root ball remain. They should be ground down sometime this week. The 23 ton crane / boom truck was unable to reach and remove it.

The significant debris from the chimney / side collapse has also been removed and taken to the dump. The Parish contracted service has picked up the debris that was by the curb (us as well as the neighbors). The immediate area is looking more ’normal’ except for the impacted ornamental trees along our property boundary. Slow progress, but progress nonetheless.
Scott’s Found Music 2A3 amps now have 210 hours of play time on them. This is since power was restored, post Ida.

On Scott’s recommendation, I installed a pair of Furutech GTX-D NCF(R) Duplexes; GTX Wall Frames; and 106-D NCF Outlet Covers. The Furutech duplexes replaced my Synergistic Research Blue Duplexes. The SR duplexes remain for ancillary use. All duplexes are on a common ground.

I have 121 hours of draw-through time on the duplexes.
I have also re-introduced the T+A PA 3100 HV integrated amplifier into the system. I am bypassing it’s pre...and using the T+A SDV’s pre.

More on this amp driving the Nenuphars at a later date.
