I just had a customer do a side-by-side between the Weiss 501 DAC and a Denafrips Terminator+ and he said it wasn’t even close. The Weiss is far better. He does place a premium on detail and imaging vs warmth.
In addition to the Weiss 501 which is an awesome DAC, I would look at the Rockna Wavedream Edition, the Audiobyte Hydra Stack (VOX, ZAP & HUB) though the hub is delayed and even the Chord TT2 and MScaler which could be in range with a trade of the Qutest. I think all would be a step up from the Terminator+.
