A couple of additional comments that I’d like to add about ultra hifi and mid fi. Ultra hifi is music reproduction on a grand scale. It creates life size 1:1 imagery as well as clarity and realism almost beyond real life. I once heard an ultra hifi system set up in a ball room. Four large panels, maybe six all powered by separate large ARC ref amps. The orchestra was laid out before me on a life size scale in 3 dimensions. I could pick out each and every instrument in the orchestra- better almost than if I had been standing in front of a real orchestra. That was in 1989. Very impressionable on a young engineer like myself.
Mid fi is not a derogatory term. At least it should not be. It describes very musical and enjoyable systems that can be assembled on a much more reasonable budget. My HT system is mid fi and I think it sounds great. It is perfect for me for watching TV. I’m not interested in going hifi with my HT although some people are. I will even listen to music in 2 channel mode on my HT system at times. For sure my HT has benefitted from trickle down from my stereo system and I appreciate the improvement in sound. I keep my obsession focused on my 2 channel system.
I recently got an OLED TV for my HT. I have to say, that is the TV I have been waiting for all my life. But that is for a different thread…
