Little Dot MK VI Fully Balanced Headphone Amplifier - upgraded

This is a great headphone amp with a very nice warm sound. It comes with fully upgraded tubes which made a considerably sonic improvement. I also upgraded the fans to ultra-quiet ones. You cannot hear them at all. Overall this is now a much better amp than the original VI. The tubes have low hours on them and are in fact probably not even fully broken in. The output tubes are original new old stock which I hand picked from a lot from Russia. They are 6H13C (OTK 7, 30, IX 75 are samples of some more markings). The input tubes are Tung-sol 6SL7 GT. I am also including all the original tubes. This is a VERY powerful amp and hard to beat at this price. I no longer use my headphones rigs and am moving, so I am sadly parting with this amp. Shipping at asking price is included to the US. Outside US or below asking price, you pay for actual shipping.
