Nice system, and clearly one you had fun putting together. The journey is the reward and your journey seems to have given you much joy and satisfaction.
I have never heard Hales speakers but a good three-way can really hit the sweet spot, and they seem to be highly regarded.
I am also impressed with the folks on this thread who appreciate Steve McCormack's work, and I am sure your DNA-1 Deluxe Gold sounds great. I have been fortunate to have owned some of Steve's gear along the way like the DNA-2, DNA-500, and RLD-1 Platinum and, currently, a fully tricked out TLC-1, and a DNA-2 LAE that is in Steve's shop getting the works. The work Steve did on the TLC-1 is outstanding and puts it at the very top of about 20 very good sounding preamps I have owned, including the RLD-1 Platinum and a VTL TL 5.0. If you can swing it, I strongly recommend getting another TLC-1 and having Steve work his magic on it.
I envy your modded DAC-1, and always wanted to hear one. Steve himself told me that, when modded, DAC-1 is incredibly musical.
Enjoy your well thought-out system, and give that TLC-1 option considertion.
Best regards,
