Since your goal seems to be objective fidelity, I would put more stock in measurements than subjective listening impressions. Having said that, out of all the Chord DACs I've listened to over the years (DAVE - with and without M Scaler, Hugo2, Mojo, and Qutest), my favorite is actually the Qutest. It also happens to be the DAC that measures the best. Coincidence? Perhaps.
Audio aside, it may be best to spend the money on those new bathrooms for your family as another poster mentioned. They're much more important than gadgets and gear.
