Well 7 weeks since my last post and I still am completely enamored with this amp. The LP is excellent+ with my M1060 and M1070 planar's. The LP sounds very, very good with my modded Sennheiser HD599 using the single ended headphone output. Speaking of single ended, after much listening I find I like the single ended outputs of my DAC's to the LP's single ended inputs best. But all my balanced digital sources have D/S chips and my single ended DAC's are RTR/ NOS designs. I thought the reason was probably that I much prefer RTR designs. But, with more listening I determined I like the single ended outputs from the D/S DAC's better too. Single ended is richer sounding and I like the treble presentation better. Balanced out to the headphone is the best by far with my planar's no question. The Sennheiser HD58x sounds like ass balanced on the LP. I like this amp so much I just bought a used Liquid Gold from Adam/ Ilikebananafudge for a great price. Can't wait to try the Gold!
