I also have NAT monos, but mine are PP for 125W of pure Class A 805 tube goodness although PP. Theres no other way to keep things differential through my rig than PP if the amp is using SE tubes. I did finally try Jeff Rowland SS monos which altered my experience and went with 4 model 12 monos in a biamp config. I actually tested the Kinki integrated in the top position vs the model 12 monos ive got there there and you can actually watch and listen to the comparison on my YouTube Channel under "OCD HiFi Guy" In that comparison it was probably an unfair shake as clearly the Rowland monos had more muscle, But...... do not fret, Kinki has just released to me the newest EX-B7 Monoblocks. These are a game changer, even for people already using big bad ass monos... they are twice the power per block as the integrated and twice the power supply heft as well, and a ridiculous $3300 per pair. I have negotiated a full month of exclusive GLOBAL distribution for the next 30 days, so that means I'm excluding the rest of the world in order to make ship times faster for my USA + Canada buyers. Look for the 6 moons review as Srajan has started it and he will be receiving the newest monos tomorrow or the day after. I'm glad to see that Kinki stepped up their game Integrateds are cool, but Monoblocks dominate.
