02 x bat vk55 monoblocks an overkill for Harbeth?

I could hv a vk75 on loan but not the monoblocks hence can't really tell how they would sound. By itself, I realize tat vk75 & vk55 are really quite different sonically. Cannot really put athumb to it.

I could also trade in my vandersteen 2ceSig2 + M30 with reasonable cash topup for a pair of dealer's demo vandersteen quatro.

I suspect that a single vk55 wld hence be insufficient...

Any more comments appreciated ;)

2 x VK55 would not be overkill for the M30s.
The M30s do like power & more seems better up to about 150w/speaker.
Good luck.

thank u nolitan!!!!
