Harbeth SHL5 compared to Merlin VSM ?

I have owned both speakers but in two totally different systems. I think for the money the Harbeth's are hard to beat.

OK, thanks for the ideas; someone else mentioned
ATC.

Hey Underdog, you have a nice system--
I heard those Temptations about 10 years ago at (the late) Soundex in Willow Grove PA, and still remember it as maybe
the best sound ever (on a female vocal). And the Dartzeel
electronics made for another of the best of the best
driving Von Schweikert VR9s an the NY HE show a few years ago.
So you sure have good taste.

Having heard both only at CES/THE Show, my preference for vocals was the Harbeth HL5 as I heard them with Resolution Audio digital and amplfication. The Merlin VSMs with Joule Electra monos were a clear choice in terms of piano music, liquidity, purity of movement through the upper midrange to treble. However, Harbeths sounded better for vocal music. Both excellent speakers, of course. YMMV.

between the 2, harbeth. add atc, spendor, ohm and a few other (now gone)classics such as dunlavy, hales to the short list

What surprises me is that all the comments so far don't mention anything about what gear you will be using it with. This stuff needs to be paired with appropriate electronics, and without knowing what you've got, and if you plan to making other changes to suit your chosen speaker or not, makes a big difference.

FWIW, IME The Merlins can provide a level of transparency in the mids and treble that will let you hear more of what's in your recordings, and prove more satisfying over the long run.
I've always found the Harbeths pleasant but lacking. Yeah that will make some crappy recordings more tolerable, but in general that kind of thinking is not how you want to build your system.

Disclaimer: Merlin owner. That's because I think they are one of the best values in all of audio and can be the centerpiece of your rig up through very high levels of performance. Cheers,
