I'm putting the majority of my backup/standby components back into service, for a summer place streaming stereo! The signal path includes a Bluetooth receiver, separate dac, integrated amplifier as preamplifier, power amplifier, and stand-mounted two-way sealed enclosure monitors. The integrated amp in the early 1970s was for my first college dorm room. I had to have the power amp refreshed, bad solder joints kept it from starting up after about 10 years of sleep.
It's going to be a hoot! I already think I'll order replacement mid-woofers and tweeters when the timing is appropriate, and maybe updated crossovers if necessary. The speakers are mid/late 1970s vintage.
