I concur that those 50's/60's McIntosh lower power amps were phenomenal.
The MC30s drove my Legacy Focuses which have low impedances. Stock, they are rather limited in bass and highs but the best mids ever.
The 1990s SS McIntosh amps were unable to drive my former ML Monolith IIIs at all (neither could Levinsons). Terrible mismatches. However, those powerful SS McIntosh amps of today can easily and beautifully power Maggies of all sizes.
