我不是Naim 用家. 只是如果不用Naim Nap 250的話.. 我印象中Nait XS2 的 Power amp In 和 Pre-amp out 之間應有個大圓插應是有個東西?
看看英文說明書的P. E12:
Note: The link plug should be removed only if a power supply upgrade is to be used, an alternative preamplifier is to use the Nait XS 2 power amplifier section, or an alternative power amplifier is to use the Nait XS 2 preamplifier section. It should remain fitted in all other circumstances.
