IF you have a great deal on the ATI6005, you may want to check it out! But you also have the choice of going QUAD XPA-1 gen 2! I would select that choice (if you have tons of cash).
Transport: Sony UBP-X700 UHD-Blu ray player spdif PC using Musiland Digital Times WASAPI via BNC connection - DAC: DC-1->XLR XPA-1 , RCA->Basx A-100 CD: Denon DCD 600 PCM 61 DAC. RCA Amp: XPA-1 gen 2 using XLR connections. Speakers: Axiom Audio m80 V3, Sennheisser HD700 headphones. two pairs 12 guage each bi-wire speaker cables per monoblock Headphone amp: Basx A-100 (INCREDIBLE VALUE!!)
That ATI amp is very heavy haha, two of the new XPA DR1 amps may be a nice way to go, the new reference monoblock, my Sherbourn PA 7-350 weighs 99lbs and it wasn't fun putting it in my rack by myself lol.
