Considering Harbeth C 7ES-3

I have the 40.1's and think they produce as accurate a sound as one can achieve in this hobby. I always compare them to the original Quads that I had for 30 years....so natural but without the limitations of the Quads. But they do benefit from powerful amplification. You may be able to find a used pair on the internet that would save you some bucks. As a caveat, I've only heard the 7's several times in short listening sessions but they should sound reasonably similar to the 40's

I owned C7's for about two years after my Quad ESLs quit
They are exceptionally good speakers with a very sweet treble
I was so impressed I decided to step up a notch to Harbeths SHL5+
but I could have lived very happily with the C7's

I have two Graham Slee Golds and they are very uncolored and natural sounding but they are not SUT's....they are to be used after an 
SUT or directly with a MM cartridge. They're at their optimum with the optional power supply

oooops!!!!! sorry about my last post. It was supposed to be in response to a fellow stereophile who is looking for a quality phono preamp

@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.
