Since you liked the Harbeths I would try the 30.1 or 30.2. I preferred them to the SHL5. The suggestion above of the P3 could also work if you added a sub seeing as the low end was the problem. I don't notice any issues with the low end in my 30.1's. They're in a bedroom that is 14' x 23' with 11 foot ceilings on the long wall. Imaging is unreal while bass is tight and surprisingly full.

Hoping to get input of fellow members to help with speakers. The most challenging part of my search for audio bliss has been speakers. I've had Thiel 1.2, Monitor Audio Gold, Cary Silver Oak, Zu Essence, Ref 3A MM deCapo BE, Magnepan SMG, and Harbeth SHL5, to name a few. Most have shortcomings but the Harbeths and Magnepans gave me the fondest listening sessions because of their liveliness and imaging. I'm basically looking for something that will just put out what its fed, play well, and basically disappear. I listen primarily to vocal and acoustic music and enjoy 60s and 70s rock and R&B recordings. System consist of LP12/Origin Live/Lyra MC, Esoteric SA-50, David Berning ZOTL Pre One, VAC Renaissance 70-70/Lamm ML2.1/JA Burgess SE45 with Chord and Siltech cables. Hoping to keep the cost below $5K. Any input is appreciated.
