$3000 stand mounted speakers?

Legacy Studio HD

Harbeth P3ESR (with or without adding a REL sub) will be the only speaker you ever need to buy again

The Dynaudio Special 40 is a fun speaker at this price point. Not the most neutral and I found the mid bass to be under damped (cello wolf tones were a problem), but dynamic and engaging with a nice full sound. Maybe not the best match for an SET amp though. I’d also check out the Silverline Minuet Supreme ($2k) - not a looker, but remarkably refined and musical, and should be very tube friendly. I have comments for both on my blog (TAWW.co)

Another +1 for Fritz Carrera 7 BE. I think they run around $3.5k now. My favorite so far in my 15.5 x 10.1 ft room. Here's a binaural recording of them which may give you a 10% sense of how they sound in real life.

I have always had EL34 amps and stand mounted monitors, since 1978 when I had the original Rogers LS3/5a and a Marantz 8. Have been through many combinations through the decades and some years ago settled in on the ProAc Tablette Anniversary driven by a Primaluna HP Amp. 
About three years ago, I entered a similar quest thinking that I could take a step up from the ProAc.  I listened to the Harbeth P3ESR and liked them at the dealer, but side by side at home, I thought the ProAcs were better, primarily in soundstage, imaging and tonal quality of female vocals.
I then decided that I would have to go beyond the $3k price point to get a step up.  I listened to the Joseph Audio Pulsars, and was really impressed, then they came out with the graphene version, which I heard, but not side by side to the original. I knew I could live with the original version, so I went on a quest to find a used pair of pulsars. Joseph audio does not have a big dealer network, but I was impressed enough with them that I was willing to buy without a home demo. Over the period of ~3 months, I found two pairs in the 4K-5k range, but missed out on them to other buyers.

So how does the story end? I listened Maggies and bought them.   But, you know the audiophile story:  talk to me again in 2-3 years and I might be looking for a good stand mounted monitor in the $5k range.  What did Harry Chapin say? “All my life’s a circle....”
