We auditioned a Mac (MA 352) this morning (we are looking for a new amp). The tone controles were quite useful in a few cases (to my own surprise, we haven't owned an amp with tone controles for decades).
Hyperion releases a free sampler every month. I think they are fun. Backside: you will end up buying more music than you intended (nothing wrong with that, though; I do not use Qobuz or something similar).
