You can try the DCB1 or the K Buffer with a passive volume control after the DAC. May be borrow from a local FM and try out in your system and you may like it.

Preamplifiers with unity gain are known as buffers. Passive attenuators are just a volume pot or an resistor array however there may be problems with impedance matching however buffers usually don't have such problems.
