Forgiving, musical speaker....

Indeed...sorry for the typo

This question is right up my alley as I have been listening to the Kestrels as my go to speakers for about ten years now. Actually decided on them when I owned a pair of Vandy 1Cs and had to sell one or the other. In my experience, the Kestrels are one of the most natural sounding speakers bar none. Liked them so much I once owned three pairs.
Because internet buying has been so easy I have tried many different speakers searching to better the Kestrels. The speaker I like as much as the Kestrel is the Soliloquy 5.0 monitor. Surprising as the main thing they have in common is they are both from companies no longer in business.
Meadowlark Kestel IIs, Shearwater Hot Rods, Magnepan 12Qr, Thiel 1.6, Dynaudio 1.3SE, Dynaudio Focus 110, Proac Response 1.5, PSB Platinum ?? and a few others have been on and out. The speaker I am using now, that I think is here to stay is the Audio Physic Tempo IV. These speakers have a wonderful soundstage with depth and width, great bass and the most detailed, yet forgiving treble I have experienced. I suffer from mild tinnitus which makes harsh treble hard to listen to. With the Tempo IVs I seem to be able to listen at higher than usual volume with no discomfort. It's something common to both the Kestrels and Soliloquy, and I lobe that.
You didn't mention price but a pair of Tempo IVs was recently listed here for $1250. Seemed like a real bargain for a speaker that listed for $4k+ just a few years ago. Good luck.

Most any Harbeth is quite forgiving. Even the baby P3ESR that I recently sold.

The Harbeth Compact 7 is what I have and its as forgiving as you could ever imagine. Simple to set up with the right stands. Doesn't matter what cables you use for the most part. Almost any amplification mates well. If you just want to listen to your music without constantly being critical then you will like them.

Mirage OMD-15. Originally $2500/pair, they are now available through vanns.com for $800-1000/pair with free shipping, return privileges and full factory warranty. They have a 9" x 11" footprint and are slightly forward-throwing omnidirectional. They *can* rock out because they have good dynamics and clarity, but really excel on vocals and acoustic instruments. I love mine for jazz, acoustic pop, Sinatra/Krall/Bennett, James Taylor, Miles Davis, etc.

They are placement-friendly and throw a realistic and very stable soundstage. Excellent speakers for parties or for puttering around the house as they fill the listening space very evenly regardless of where you sit or stand. Very natural sounding and engaging.

If you later crave more resolution, all you have to do is upgrade the electronics and cabling, and the OMD-15s will rise to the occasion. I use mine both for casual *and* critical listening. They give up lots of music without beating you over the head with edgy detail.
