New to Music Fidelity A308 A couple of questions


Hi,

I just bought a second hand Music Fidelity A308 to pair with B&W 7CDM SE speakers. Love the sound so far but I have a couple of questions.

1.  The A308 is dual mono with two sets of binding posts per channel. Can I bi-wire and use all 4 posts (2 red 2 black) for each channel or should I just combine?

2. When I plugged the DAC into the CD input I got a low level hum straight away. I noticed this with different set of speakers. However when I plug the DAC into Aux 1 I get no hum it works perfectly. Any ideas?

Thanks

Yes, you can. 

"...I plugged the DAC into the CD input I got a low level hum straight away..."

No idea on this one, they should be the same. 
As far as I can tell, the connection should be CD output into DAC input ... then DAC output into preamp input. 
My two cents: congratulations on on acquiring one of the best values in an older amp.
I’ve got one and I love its synergy with ATC speakers.
I agree with the last poster in reference to your questions.
