My largish listening room treatment consists of things I own, including a smallish spinet style piano, furniture, books, an oriental carpet, collections of vinyl, CDs, and wax cylinders (actually no cylinders but I tossed them in anyway) and a tall sloping ceiling with side walls far enough away to obviate the dreaded "early reflections" (a great title for a book or music album, or a clothing line made from sheet metal). Also the addition of the remarkably technically advanced Chicken Head knobs on my REL subs to make them easier to turn up or down a little if needed. Chicken Head knobs are far less expensive that DSP gizmos, and add somewhat less pollution to the signal. You do need a small screwdriver for some of them.
I can not live without "Room Correction"
Accuphase DG-28
I had been using Accuphase Digital Equalizer since 2001.
It is still working fine.
With room correction, the overall balance is much better with tighter base and flat high frequency.
I can not live without it.

Recently Lyngdorf got very popular with good room correction capability.
But I am a tube guy enjoying good timber out of it.
I will not go for Lyngdorf as amplifier.
But I recommend other people to try room correction.
