Looking for best speakers to pair with my Aesthetix, Mimas integrated amp...

I have an interest  in the Harbeth/Tannoy/Fyne sound. No real way to audition them:(

Don't take my word for it.

I'd suggest two Velodyne GmbH DD-10 Plus subwoofers positioned using the subwoofer crawl prior to Auto EQ which can then be manually adjusted to your personal taste to any future system changes.  

The Pulsars are pretty darn good speakers.  What specific improvements are you looking for, what’s your budget, and are you looking for new or used?

Tekton has a speaker for anything you need from small to big ulf brich no matter whaT you price range. I have some very expensive reference speakers from known major brands and these are 95% of those reference.look at thier website call the owner,Eric tell him what you want he will guide you many European major brands are coping his design. Biggest bang for buck this should get the party going  enjoy the education and the hunt.

A great speaker for the wonderful Mimas integrated is the Vivid Audio Kaya K45.  You'll have a wonderfully musical high end system.
