Description
El Cayin Soul 170C es un preamplificador totalmente a válvulas concebido para puristas del sonido analógico. Su arquitectura — completamente cableada punto a punto, con transformadores de alimentación toroidales hechos a mano, chasis de aluminio macizo y paneles laterales de nogal — refleja la filosofía clásica de construcción de “alta fidelidad de verdad”, donde cada detalle cuenta.
La señal recorre una cadena de ocho válvulas cuidadosamente seleccionadas (ECC83, 6SN7GTB, 6CA7 y 17AX4GT), lo que permite una amplificación limpia, dinámica y con la calidez propia del tubo, manteniendo un suelo sonoro silencioso gracias a una relación señal/ruido de 100 dB.

Delivery, as always, the very next day and everything was spot on; seeing it in person is truly impressive – the build quality is outstanding, once you plug it in and play it, it’s like rediscovering your entire discography thanks to the musical warmth and the information it provides. It’s a top-class piece of kit in every respect; from any other well-known brand in this field, it would undoubtedly command a five-figure retail price. Many thanks to the team at Lyric.
