In their July, 2025 issue, Hi-Fi+ magazine published a glowing review of Doshi Audio’s Evolution Line Preamplifier. Deep Dive audio is proud to be Florida’s authorized Doshi Audio dealer, and we congratulate Nick Doshi and his team on this well-deserved accolade. We couldn’t agree more with Hi-Fi+ on this truly spectacular preamplifier! And we hope that you will make an appointment with us to hear Doshi Audio’s line of tube amplifiers and preamplifiers for yourself!
“Preamplifiers possess the peculiar tendency to be slightly more than the sum of their engineering. Two designs with appreciably similar engineering can yield radically different performances, and some specific models may prove to be considerably more than their theoretical components. Doshi Audio has established a strong reputation in this field since its founding nineteen years ago. The Evolution Line Preamplifi er is part of a small range of components produced by the company. At first glance, the recipe for the Evolution Line Preamplifier appears straightforward. However, like those deceptively simple dishes encountered in high-end restaurants, it is both more complex than it initially seems and composed of exceptionally high-quality ingredients.”
“This is one of those rare preamplifiers that possesses a degree of magic in its operation, going beyond the unquestionably excellent engineering it features. What has captivated me about the Doshi is that this magic isn’t a constant, attention-grabbing aspect of its function. It’s transparent, utterly tractable, and built like a lorry. Still, when your equipment might typically struggle to resolve everything as logically as you would hope, it steps in quietly and unobtrusively to enhance the experience. This is a truly magnificent preamplifier that will deliver outstanding results across a wide variety of systems.”
