@mdalton All the ’phone’ conversations we’ve exchanged, including those with Op, are not an attempt to substitute the cell phone as the main streamer. Instead, it’s an open discussion on the ’possibility.’ I have Ifi ZS myself, two of them, with one fed by Ifi iPower X and the other on a 25 VA LPS by Lhy. Both serve me well, but I find my iPhone 13 is no slouch either. Whether it is used as a backup is strictly up to you, but I want to emphasize that it should be a personal choice rather than a prejudice. I want to give the iPhone a fair trial and do it justice.
How you like your D70 Pro Octo? I have tried couple of sub. $500 Topping dac and return / sell all of them due to basically flat SS (lack of depth). Curious about Octo given all the rave reviews.
