I think Mc amps sensitivity can lower than some other amps. For example my mc402 can take 4v balanced input. Some DACs and preamps will have an output in the 2~3v range. I assume the Mc preamps have a 4 watt output. I'd be interested to hear more on this as I have a dac (Transporter) with max balanced output of 3 w and it's run straight into the 402.
