In the curiously paired room sponsored by Pass Labs, it was possible to get a good sense of the superior cleanness and neutrality of the new XA 60.8 monoblock amplifiers ($12,800/pair). This was due, in no small part, to the Pass Labs XP 25 phono stage ($10,600) and top-of-the-line Pass Labs XS preamp ($38,000), together with a modified Technics SP-10 Mk.2 direct-drive turntable equipped with a My Sonic Lab Hyper Eminent cartridge, an Oppo BDP-105, homemade speaker cables, and Silent Source interconnects. But there was no getting around the fact that the weak link in the chain was the loudspeakers.
As Pass Labs' Desmond Harrington explained, the speakers, built many years ago by twin interns, are a home-built design that incorporates Tannoy dual-concentric drivers into a Jensen Imperial folded horn cabinet. "We use them because they're 98dB efficient, and are a full-range point source. They're purely a tool to listen to amplifiers, because they let you hear everything, good and bad." That may be true for folks accustomed to the sound of these homemade loudspeakers, but to this listener, they overloaded the room with bass, and delivered a bass-dominant presentation that marred the unique beauty of Pass Labs electronics.
As someone who loves the sound of Pass Labs products, and has long-lamented the absence of a Bay Area dealer, I wanted to not only hear far more of their gifts, but also experience once again the .8 series' superior bass control. I'm sorry others couldn't as well, because their sound is very, very special. In my opinion, someone who loves the smoothness and beauty of tube electronics but wishes to explore the sound of solid-state equipment would do very well to try Pass Labs electronics. As a former tube user, I've found the Pass Labs class-A lines an ideal mating of grace, beauty and power.

Посмотрел на чертёж корпусов выше и задался вопросом -Стоит ли заморачиваться с точным повторением всех деталей и размеров? Что такого произойдёт без камер или в иных пропорциях? Ну будут чуток по другому бухтеть. А применительно к разному усилению разница в звуке ещё больше и по бОльшему количеству параметров.. Всё больше похоже не столько на улучшающие решения, сколько на решение проблем статусных кабинетов.

Полностью согласен, а если ламповый усилитель еще и не дорогой, тогда вдвойне приятно https://youtu.be/Mqk7Rc240ew
