Glad to see you have finally got your Hugo. Now on warm up, I agree things sound better the more times you listen to Hugo. I have been listening to one since September, and I swear it sounds better now than then - it very much has the ability to surprise even 8 months on - I was listening to some castanets today, and the click was extraordinary - very sharp, and precisely focused. So is it Hugo breaking in, or my brain breaking in to Hugo, or is it that Hugo has the power to surprise like live music? I do not know - but I know that getting used to Hugo sound is not something that happens quickly, and it is something that you will find sounds better and better - but doing careful listening tests with old units and new units does not reveal a big difference in sound.
Another point in a posting earlier - it does not matter which source is selected, DoP will be decoded to DSD on all inputs.
Oh my.. Mr Rob, you have finally arrived here. Welcome to headfi..your presence and contribution will be greatly appreciated.
