"When I first listened to the tape I thought, this is so good that if I do anything else in my life, I have to make sure the world hears this," David Prinz says with obvious intensity. "That's how I really feel. It makes me happy that all these Gram fans are finally going to get to hear what he was really like live."

The love of music can drive human beings to astonishing lengths. For Prinz, cofounder/owner of California's Amoeba Music chain, that fervor revolves around the work of country-rock pioneer Gram Parsons. Despite the often-outlandish mythology that's grown up around this shooting star since his tragic 1973 overdose at age 26, Prinz has made it his quixotic mission to find, restore, and release unreleased Gram Parsons live shows.

I can roll out of bed and install a $10,000 phono cartridge while finishing my coffee, but I postpone DAC installations until I am in the exact right mood to handle the potential stress—especially DACs with a touch screen and a complex menu. To my delight, Ferrum Audio's new Wandla digital converter was completely stress-free to install. It took only minutes to connect the USB-C cable, the Cardas Audio Clear Beyond interconnects, and 24V DC power adapter.

Connecting the power adapter caused a power-switch symbol to appear on the front panel touch screen. The moment I touched it, I smiled like the Cheshire Cat, because I saw a USB-C symbol, a loudspeaker symbol, three dots in a box, and a volume control bargraph. That told me the Wandla recognized my chosen input and was waiting for a signal. All that remained was for my Roon Nucleus+ server to recognize and enable the new DAC, which it did without prodding or reprimand. For me, that was a wow moment, a good start to what promised to be an interesting review.
