@jnehma1 thanks for the follow up. It may not be apples to apples, but seems close enough for general discussion purposes. And, to be clear, I was focusing on the 3400 vs Manhattan II, not the 1120 (which I agree would not be fair).
The Manhattan II can include a network card to make it a preamp/DAC/streamer. I’ve been offered a great deal on one that I think I’m going to take. Replaces my DAC, preamp, and streamer in one box. Later, if I want to warm it up further, I can go separate tube amp. Seems to make the most sense to me. If I do pull the trigger I will report back.
