I have MC501 mono's powering Vandersteen 3A signatures.I use two stereo pairs of speaker cables to bi-wire them.After trying all possible combinations.I use the 2 ohm taps for the lows,and the 4 ohm taps for the uppers.Sounds the best for me.I also utilized the same taps when I was using an internal bi-wire cable previously.As Mac states,using multiple taps is not an issue.
McIntosh MC 601 Using two taps at the same Time
Has anyone use two taps at the same time 4ohms and 8ohms taps on a Mac amp? I usually use a biwire for my Vandersteen 2CE Sig II but I would like to separate the biwire as in, tap the lows on the 8ohms tap and tap the highs on the 4ohms tap to get a little more low end (bass). According to McIntosh, since Mac uses the autoformer, you can use two taps at the same time.
