"Give me the seduction, give me the pleasure," Ron Sutherland was nearly shouting into the phone. "I want to turn off the analytical mind and just enjoy myself!"

Sutherland speaks in the chipper Midwestern cadences of a comic character actor from the 1940s, sort of like a grown-up Eddie Bracken from The Miracle of Morgan's Creek, and I'd never heard him sound so excited. He was talking about his new phono stage, the Dos Locos, the first product he's designed collaboratively, having enlisted a group of audiophile friends who listened to and critiqued each iteration. "These friends are excellent listeners," Sutherland related, "whereas I'm a gearhead, and don't have the patience or discernment for that kind of listening. Sometimes I'd change something and they'd say, 'You made it worse!'" It sounded like he preferred the group dynamic. "There was something very intimate about this back-and-forth process," he told me. "And compared to working alone, it was a lot more fun!"

Myriad distribution factors drive and affect the hi-fi marketplace. Ultimately, these can impact end customer purchasing choices. Recently I've written—including in the December 2024 issue—about evolving new distribution models and how the term's meaning has shifted somewhat: Some companies have been expanding (or in some cases reducing) the kinds of services traditionally provided to exporting international manufacturers.

That made me curious about how business is going for "traditional" distribution companies. That is, companies whose services typically include handling importation, warehousing, shipping, and working with retailer partners and dealers in other capacities. They support retail dealers with the inventory they need.

Back in 2016, I documented the rise of class-D amps using the early TriPath technology. Used in the Bel Canto eVo 200.2, TriPath cracked open the door to the High End but was never admitted due to a dim and opaque treble. The second wave was based on B&O's ICEpower technology, again via a Bel Canto amplifier, the Ref1000M monoblock. ICEpower had more credibility and was accepted by many but, often, only with, ahem, due consideration for size and efficiency. There was an explosion of new class-D amps in 2016 when Stereophile featured glowing reviews of Bel Canto's e.One Ref600M monoblock, Theta's Prometheus monoblock, and NAD's Masters Series M22 stereo amp, all based on Bruno Putzeys's Hypex NCore technology modules. Finally, it seemed that class-D was "in the room," though, even to this day, there remain critics and quibblers who continue to deny them as true high-fidelity products.

Well, time does not stand still and neither did Bruno Putzeys. He, along with Lars Risbo and Peter Lyngdorf, had founded Purifi in 2015, and in 2019 he unveiled the Purifi Eigentakt power amplifier modules.
