I’m curious what you find to be the weakness & strengths of the Holo May DAC KTE? This might give you some direction as to what preamps you want to look at. I’m using a McIntosh MA12000 integrated. The May is fed via an Aurender streamer and I’m using Wilson Sabrina X/REL s812 subs. I’ve been happy with the May, but Juan recently listened and thought there was a high frequency hash courtesy of the KTE. My hearing falls off pretty sharply at 8K.
