This seems like a great “critical use case” scenario… and I’d guess the M1 plus large size Liquid Retina screen options would be determining factors. Not my thing, so cannot give any insight… I don’t even use the pen, never mind do free hand drawing! Envious of your skills. That said, successive upgrades might not be your best bet: jumping in at the (expensive) end will give the most representative experience and, should worst come to worst, I bet you’d recover more from your investment if you downgraded than from moving on an older, lower spec (especially non-M1) model. Worth checking used price history if you can.
Agree that “any old iPad” provides a great user experience as a music controller, whether via Naim app, Roon, or whatever else. To be totally transparent, though, I almost always use my iPhone for this and have never really had complaints or wanted (much) more.
It is fantastic, and again an extravagance that is under used chez moi. I enjoyed it as a night table headphone amp, fed by a Raspberry Pi running RoPieee as a Roon endpoint, but I don’t do that very much any more. I use it as a DAC driving powered Dynaudio monitors on my (NUC + Windows, soon hoping to be Mac mini) desktop but also have the MOTU M2 for that, which sounds equally great and is also an input audio interface. I am going to use it in place of my Topping D30 (first inexpensive standalone DAC I purchased to explore Roon streaming via RPi into an old analog NAD receiver) in my bedroom system (overkill, and temporary while our Atom is at a second home during my wife’s posting abroad).
My goal today is to put it into the main system Nova and compare vs native Nova performance. I’m not bothered by the ADC-DAC cycle, as that’s an obviously well-solved problem in DSP for systems that own both halves of the conversion: the Nova is a great digital preamplifier, no doubt. The Topping D30 was noticeably more grainy and less satisfying when I tried that out a couple / few years ago… whew, glad it was obvious at the price difference! The RME is higher priced (about $1500Cdn vs less than $150 for D30) and comparable to some fraction of a Nova - say 20%? - putting the cost of a Nova DAC at about $1200 - $1500… but it reviews and in my experience it performs extremely well … so I’m interested in this more apples-to-apples comparison. I have no serious intention to upgrade from my Nova to, say, an SN3 plus NDX2… but this experiment might point out what might or might not be on offer with a change. The loss of family useability is a non-negligible consideration of course, so even though I’m not convinced that Naim streaming DACs are necessarily the best price/performance here in Canada, the integration and reliability are also value-for-money factors to me. For today, though, just a bit of streamer+DAC fun (including a chance to compare Apple Music vs Roon+Tidal, and iPad vs RoPieee).
Long winded yet again! Thanks for reading this far. Very interested in your own thoughts and priorities for next steps both with your iPad and streaming music in general.
