Amplifiers in use with big Harbeths (Mon 40 series) that work very well

thanks for the input so far - i am aware of the usual suspects, but wanted to check to see if there are any ’out of the ordinary’ synergistic matches out there

and yes, well aware of the amp discussions (as sad as they are) at h u g...

appreciate the inputs and discussion so far

the mon 40’s represent an interesting challenge for amplification... highly resolving, not super hard to drive, but hard enough that really low power amps need not apply -- moderately efficient, so doesn’t need a ton of power, but really likes more power if it is uber pure

responds well to tube beauty but with the big woofers you will certainly give up something on the low end in the trade

like many great speakers, it may have some of its own personality but it let’s you hear pretty plainly what you are driving it with, good or bad

my intent in this thread is to garner responses from users of mon 40’s only

i have super 5s and compact 7s they are rather different kettles of fish

@atmasphere

yes, fair points ralph, with which i agree

i guess in my own experience, there is a fairly decent correlation between large woofers such as the single 12 inchers in big harbeths and spendors with the need for amplifier damping factor and control of the driver and its significant motor structure

no argument that other configurations such as speakers using multiple smaller woofers like those in focals magicos wilson/wilson benesch etc etc with lower total impedance in the bass region as seen by the driving power amp are in fact often more challenging loads for the amp to handle
