Does Mcintosh MC75 drive B&W 802D well?

I have a pair vintage Mcintosh MC-75 mono amp. I have a chance to buy B&W 802D speaker. Not sure they can working well together.
B&W 802D sensitivity is 90db. Manufacturer recommended amp power range is 50-500. A 75 watt per channel tube amp will not bring out the best in that speaker.
If the speaker posses a relatively flat impedence curve and doesn't drop below 4 ohms then you should be fine. Of course it still depends on room size, type of music and how loud you play it.

I don't think it proves enough juice. The tonal propeties are probably fine...rolled off highs, but those speakers need more power
