I'm the original owner of this Luxman P700u headphone amp in excellent condition. This amp was purchased from a Luxman authorized dealer in the USA. It has single ended and balanced dual 3 pin XLR outputs. It has 2 pairs of balanced inputs and one pair of single ended inputs. In balanced output mode, it puts out 4.2 w/Ch. I've used this amp in balanced mode with balanced inputs to drive my Susvara and Abyss 1266TC. The amp is in perfect operating condition, very quiet and powerful. I'm only selling it to make upgrades to my speaker based system. Other headphones that I've used with this amp with excellent results include the ZMF Verite Open, Focal Utopia, ZMF Aeolus, LCD 4z, LCD X, and HiFiMan HEK SE. At the asking price, PayPal fees and shipping within the CONUSA are included. Buy with confidence, I have perfect feedback here and on Audiogon (Smatsui).
