Used my dad’s McIntosh MC60s (1965 or so) for a while. A combination of the local repair guy dying, Mr DeWick’s retirement, and one more shorting out, they got the boot. As we are moving to be with our daughter and youngster at the end of the year, those tubes were not going to pass WAF to exist near the child. I did like the sound.
Oldest part of my system appears to be the Oppo player.
I have the Headroom Balanced Amplifier, and original Holo Audio Spring KTE DAC in my business office, with OG Senn HD800s.
