No Tridents yet, but everyone seems to recommend them. I missed out the last time they were in stock, as they sold out quickly. I also use a Salas shunt regulator on the Legato, but opted to use the TP Placid for the Buffalo. I managed to replace the stock 1000uF cap with a 3300uF Nichicon Gold Tune after some careful surgery. Legato 3 should be very good, and I agree balanced out should be used to get the very best out of it. That said, this opamp output is quite good, and I'm glad they include it. I hope to use it in a bi-amped setup (350hz and down), and use the pristine balanced ouputs to a pair of class A power JFET Circlotron monoblocks for the top end.
