Will an Amp change improve my system ?

@carl292 Sorry for your loss. I have not heard of Judge Joe Lodge though I did once get dismissed for jury selection in SB. I think the judge was a bit amused at how that happened with my interaction with the prosecuting lawyer.

My wife may have heard about him since she worked as a nanny when she first came to the US with a prominent family involved in the legal system. She was at the Michael Jackson trial but almost got kicked out of the court because of her disapproval facial expressions during the trial.

I’m now using a Freya plus with one of these new GaN class d amps and can strongly recommend in all regards.

Was running Hypex n core prior. 

I was going to suggest a pair of Atma-Sphere Ganfet class D amps with your Freya.  You won’t believe how good they are.

Pass XA25 https://www.usaudiomart.com/details/650168182-pass-labs-xa25-class-a-amplifier/. I still believe in class A, pure class A. This low wattage machine seems having no issue driving low efficiency 84-86 dB speakers like Quad ESL and Magnepan .7 so may not have issue with your Harbeth either.  Otherwise, consider Accuphase A-48 ( https://www.usaudiomart.com/details/650119484-accuphase-a-48-pure-class-a-amp/ ) which I have auditioned before.  Stable high current down to 2 ohm.
