or

2) A modern (2023ish) 150 WPC (into 8 ohm) Higher End Class D (dual hypex modules I think) power amp?

I have read comments elsewhere that Class D excels with bass control and is better with less efficient speakers, so it might yield tighter and cleaner low end with these low efficiency speakers. I have also read there is no substitute for power, and that Class D is trash (so many people hate on class D!) so a good A/B power amp with more WPC will give the best performance.

Looking for peoples input and experiences that might help me get the most out of these beautiful speakers.
Has the vintage amplifier had the power supply caps changed? If not, easy answer - avoid it.
