The Mola Mola Ossetra monoblocks (on loan from a friend) are exceptionally capable, with state-of-the-art invariance, linearity, neutrality, power and transparency. They are my current benchmarks for auditions and comparisons with “super” monoblock amps. The Aurender N30 server/streamer (mine) will also be used for comparisons with multiple “super” streamer/servers. ---

Good Morning, any chance you are going to compare to an N50? the Rendered sounds great but Qobuz connect lacks some features I like in Tidal or the Qobuz application so I am still contemplating a transport/streamer. Curious on the Mola Mola to M500 as well ---

I couldn’t be here without you guys and the incredible team at MSB! I’ll be sharing my thoughts and observations soon, as the Sentinel DAC goes through its break-in process. I’d like to take time to reflect more deeply on how best to present my thoughts in a coherent and organized way, as there are simply too many exciting topics to explore and discuss! ---

Actually I have a different question, given that the firmware update elevates the Cascade how much better is the Sentinel after the update. Basically is this a WOW vs OMG or a Holly Batman vs I’m in heaven moment, and again we need people who have experienced both (ie calling out @Dan or @Daniel_Francis to enlighten us) ---

Beautiful set up. In a separate thread dedicated to the Seismion Reactio 2 pictured in your room, I would love to hear your thoughts on those. But not here to risk a diversion from the more interesting listening impressions of the Sentinel. ---

The uniquely optimized acoustics of my listening room, supports the highest resolving power and jitter-extinguishing precision cadence of the Sentinel DAC to recreate a dense, highly articulated, appropriately positioned/sized, and totally credible 3D soundstage that is filled with living and breathing musicians (and their instruments) located beyond not just the sidewalls, but deeply inside/past the front wall.
