@charles1dad   Charles, I have not brought the T+A PA 3100 HV Integrated Amp back in system since the changes to the power supply / conditioner, power cables, etc. 

I need to do so, especially since the T+A SDV 3100 HV is well on it's way to be 'broken in' (over 200 hours of playtime on it) AND the other changes are settled (for the most).

I'll make a point to do so and report back. 
David 10 I’m going to be listening to the Nenuphar 8s in a couple weeks when we get back home from sunny Florida , really look forward to that listening event , I’ve been really stumped what I want speaker wise.

We recently down sized our home and gone is my listening room above the garage along with my Magnapan speakers and Rolland amps , I now have a much smaller room where such a speaker like Cube Audio Nenuphar could possibly perform well in .
David I just noticed you’ve done some radical changes to your system I’d like to ask about your Synergistic conditioner and power cords replacing the P.I. Audio Uber and Triode wires , you can pm me if you like , thanks .

Just to confirm that you can add a sub at a later date to either 8 or 10 inch Nenuphar’s if you so wish.

I have experienced the same phenomime you have eluded to in your very informative posts. Four months ago, I never heard of a 2A3 or 45 DHT until an EE friend/designer mentioned that it is the most refined tube one can acquire and that started the ball rolling since he mentioned that 2 Watts would drive my 98 Db+ speakers...

Two months later, Triode Lab 2A3 Monos 4.5 Watts with Hashimoto Output Transformers arrives and the clarity and dimensionality is unmistakable especially if you have efficient speakers of 98 Db+.

None of the KT88 Amps or SET 805 with 300B as drivers I have owned has the refinement, separation, depth, sound staging, transparency or the flow of sound that those DHT provides, it’s just magical and I believe the sound quality is related to its simplistic design.

I also have many friend owning 2A3 Amps and have a collection of NOS Tubes and the verdict is the JJ 2A3-40 and that’s what I’m using with some Shuguang 2A3C as back-ups which are quite good as well.
