Wound up purchasing an Ayon Spirit 2 , couldn't work the finances for a DA60. The Spirit 2 is very well built, and although I only have about 15 hours on it, very musical, good separation and decay, etc. most of all it is very enjoyable listening to music driven by this amp -looking forward to it breaking in. Came with new production Gold Lion KT88s and I passed on installing the new stock EH 12au7s - amp takes 4 - instead I am trying NOS Sylvania's - 5814s and ECC82s - one of each on each side - so far so good. Will try some RFTs after awhile. Outstanding customer service from the folks at USA Tube Audio.
