Hi all,
To summarise these 3 products :-
1. The Sony HAP-Z1ES has a built-in dsd DAC but no digital output to an external DAC.
2. The Marantz NA11s1 has a dsd dac with digital outputs
3. The Bryston BDP-2 has no dac and does not do dsd
So, for the price, the Marantz seems to be a good value with its own dsd dac.
If you need dsd, the Bryston is out. If you already have a very good pcm only dac, the Marantz lets you have dsd and also allows you to output hi-rez pcm to your hi-rez dac.
So, the Sony is good if you need both a hi-rez pcm and dsd dac.
For me, i am looking for a dsd capable media player to connect via usb from my pc to coax into my hi-rez pcm only dac and use the analogue outputs of the player for dsd duty. The Marantz seems to fit the bill for me.
Hope this helps.
