Don’t buy used McCormack DNA 1990s amps
Because their input board is at the end of its useful life, and when it fails your amp is dead and not repairable by anyone — not even SMcAudio.  Can you tell us, in specific, what particular part or component is the source of this?  
Best digital format (non streaming)
Sure there are higher resolution formats available but most recordings come only in 1 or 2.  If you want that music, the format is not in question.  Besides, you have to convince yourself that you can hear any difference with the higher resolution... 
I've been selling heavier gear for lighter gear
Earlier this year sold 110lb speakers and bought kef blade 2 (80 lbs & easy to maneuver).  ........................................................................... Anyhoots, who else factors in the tonnage of the gear they buy? Any other... 
For Room Correction DSP/Software- How often do you use it?

Seeing some old friends.  
Unusual Old School Way of Wiring Speakers
It generally requires having a special added driver in each speaker.  It was developed by Bob Carver and marketed, to this day, by Polk.  See https://www.polkaudio.com/en-us/product/floor-standing-towers/l800/ .  
HDMI cables for I2S
All the standard HDMI cables are compatible.  That is why the users of I2S chose it.  The issue of compatibility comes into consideration in terms of the devices at either end of the cable.  There are several standards for those and one must insur... 
Topping Pre90 Switching op amps?
If you want the sound of the pre90 without the hassle, then the Benchmark LA4 is the best bet. True but the price differential was unacceptable.  (I needed 3, now 4.) Nota bene:  The OP was asking about swapping op-amps in the Pre90, not amps ...
