Simon, as a classical enthusiast you might want to pay more attention to the D30 as it offers DSD playback which is becoming increasingly popular in Classical circles.Simon Hickie wrote: ↑Wed Sep 11, 2019 9:49 pm Thanks chaps. This is pretty much my thinking. The Hifiberry has the benefit of 2 separate oscillators for 44.1 and 48kHz which overcomes one of the main Raspi weaknesses over USB. £35.99 delivered from the Pi Hut. I'm veering towards the Khadas Tone Board over the D30. I've read some reports that there have been some component changes on the D30, but I need to dig further.
Anyway, I've just ordered the Hifiberry Digi+ Pro and will try this in the first instance with a cheap Chinese DAC I also have for emergency TV duties (not dissimilar to the Doc's '£5 DAC').
I'm intending to swap the Topping into my office setup so that I can experiment with DSD downloads (needs a USB connection) from Channel Classics whose entire catalogue is available in that format.
Also I can't emphasise enough the importance of a good coax digital cable. My personal favourite is the Profigold Oxypure OXYA4801 which is an OCC link that avoids crystal boundaries within the copper structure - decreasing jitter effects.
Here on Amazon - can be found quite cheap on internet.

Another good budget coax is the red one from Beresford.

As I said earlier. There is an LPSU from Topping which will drive both the D30 and a Pi player. Digital sources work noticeably better with sufficient, clean power and this is another reasonably-priced device I hope to add to my installation soon.
