国外某位测评大佬的评价,概括起来就是大耳必须高增益,即便如此还是很难推动市面上难搞的那一档高阻平板。低阻档位下声音猛,还原好动态高,高阻档位声音耐听不累,有模拟味。
原文如下:If your DAC outputs 4V or less on its XLR output, then SA-1 will be almost maxed out with headphones like Audeze LCD-4, but if your DAC provides a higher voltage like 5V (Topping D70S, Gustard X26 PRO) or 6V (Gustard A22), then that will work as a gain increase and SA-1 will offer you back more power, driving harder loads much easier.
I will tell you right away, that I don’t see the point of increasing the output impedance with 10 Ohms on its High-Z position, but you might have a different opinion or a different sound preference and that is perfectly fine. On High-Z, it smooths out the transient response, offering a softer and a more relaxed presentation, like you’re no longer listening to a solid-state amplifier, but to a hybrid tube-based amplifier.
