I am enjoying my Onkyo with Tannoy Fi customs and some RS 2.5 copper shielded cable. It all works very well but I cannot pretend that the sound is 'Hi-Fidelity' - at least as I remember it from my 30 years with a NAD set-up. Nowadays, I mostly listen to radio, but do find listening to my CDs [which are all of classical music] a touch disppointing, especially in 'difficult pieces' with full orchestra which sounds to me to be slightly 'muddied' in the mid-range, and particularly sharp when brass in involved. I know that very few will have listened to the Denon 37DAB in direct comparison to the Onkyo, but I wondered whether What HiFi staffers could let me know if the Denon would provide a definite improvement or 'upgrade' over the Onkyo, or whether I should opt for the Arcam Mini to hear a very definite improvement in sonic performance. I very much like and need the small form factor, so require an 'all-in-one' solution.
