I wish subtitles I have a vintage McIntosh 2275 Integrated Tube Amp mated to Bowers And Wilkins 805D Speakers vote a Audioquest Cables Auris Bluetooth and PLX 1000!Pioneer Turntable with Nagadoka MP 150!cart amazing sweet airy transparency audio The 901 has a lot of controls. I was wonder do you think McIntosh in the future for say the Tubes any provision for low to moderate volume levels a way to switch off autoformers for more straight line audio path and thus more exacting tube sound????
