@navyachts Sure. First, I have a small, low ceiling basement room. Large, handlaid stone foundation walls. Minor treatments (rug, fiberglas batting in rafters) but except for near field listening, it's been a slog to make any of my setup(s) sound right. So I bought a used MiniDSP SHD with built-in Dirac Live room correction and use it as my preamp. Since the SHD has kinda a studio vibe, it's got tons of connections. It took me a while to set up the DIrac - pre-measurements are a pain - but once there, it's been a gas. It locks in the imaging - important to me - making my room challenges mostly disappear. I've A/B'd it with multiple speakers and except for some really quirky things that it can cause, like suddenly heavy boom from the SVSs, once you get the Dirac happy, it's rock solid. Difference between on and off is distinct.
I have to add, the SHD comes with a separate DSP app ("Device Console") that allows L/R balancing and EQing the signal. I expected the Dirac SW to do the former but it dosen't. Anyway, I have tinnitus and high frequency hearing loss, so the Device Console allows me to compensate. You can do multiple versions, store and reload at your leisure. So I have a setup just for my ears, one for my hi-fi buddies when they visit and one for watching Dune with my wife.
Hope that answer's your questions and not put you to sleep...
P.S. Current system: Hot rodded Rega Planar 2 with Elac PPA-2 pre, Bluesound Node 2i streamer, MiniDSP SHD preamp, Bryston 2,5B3 or 4B SST, Topping DX5 DAC. Speakers are all over the map: Proac Response 3.8s, KEF LS50s, Klipsch RP-600Ms and on and on. Also have an experimental set of Lii Audio F15s baffleless with a Decware SE84UFO that's going to come online eventually. I know, I need to get a life...
