@jim51 I have a pair, bought them used on the Gon and saved a bit of money. Something I learned from spending time on Harbeth website is a substantial amount of speakers are using the polypropylene cone material. Long story short--good for low cost for the builder but not so good for best sound reproduction. Harbeth does not use poly for cone material--at least not on these.
I've had mine now for 3 or 5 yrs or so and they remain in my main system. I sold my ML's and others as well. What I have left are speakers that are primarily for low wattage amps. The workmanship is outstanding as well as the sound. highs can be etheral depending on material played. Most life like presentation I have heard in my system to date and no need to spend more. I think I spent 2200 for mine. excellent midrange and bass adequate for my needs. I dont use a sub. Good luck, give them a try.
amps currently used. Emotiva xpa100 monos. Pass XA30.5.
