pre-amp processor

I know the previous McIntosh MX-160 used the Lyngdorf DSP and processing board, but used all McIntosh linear power supplies and audio stages.  The MX-170 probably uses the same architecture since it also includes RoomPerfect.  That's the way I would go if you have the budget (either used MX-160 or a new MX-170).

McIntosh gears keep their values over time 

If you want 2.1 HDMI  , DTS X Pro , and your are mostly  ´´digital ´´  Lyngdorf is the way to go instead of McIntosh.

McIntosh is always , a litlle late in the game.

Maybe McIntosh MX 180  will have these  features.

The Acurus is both hardware and software upgradeable I don’t think that the lyngdorf is and neither is McIntosh I don’t feel like having to buy new equipment every few years
