Audio Note Neiro PSE schematic with 45 tube versus Wavac ES-300 IITC schematic


I am thinking to get a custom built amplifier, and considering the following:

Audio Note Neiro Parallel Single Ended with 45 tube (instead of 2A3)
Wavac ES-300B IITC 

I am wondering if anyone have some input on either one of schematic, or can predict what are the differences between the two.  I searched on the internet, but can't get much reviews or opinions for both of them.  It seems the Neiro would be fun.  It has 2 x 45 tube in parallel to give more power, and I hope it doesn't lose the characteristics of 45 tubes.  And if I don't need that much power, I can just use one pair instead of two, it seems.

For the Wavac, it seems the IITC circuit is special, maybe that's why it got mixed reviews.  Some likes it and some don't.

@roberjerman Thanks for the reply. Actually, I am using a (in my opinion) very good 2A3 by Triode Lab from Canada.  Since the 45 PSE also output ~4W, do you think it will sound too similar to my current 2A3, or it really depends on the schematic?
@zipost Please educate me, what is (in theory) the effect of having two tubes in parallel?  I know that it will give more power so I can play the music louder to fill a bigger room.  But I don’t need louder.  For my current 2A3, the volume knob is at about 9 o’clock.  So, I predict even for a single 45 tube at 2 W, maybe my volume knob will be at 12 o’clock?  But with two tubes in parallel, will it make any tonal difference such as having more “weight” or bass?
