Improvement by adding P3 to Stellar stack with M700

Greetings. I added the P3 regenerater to my system consisting of Stellar gain Cell preamp. M 700 amps and Jade 5 speaker. At first I was puzzled because I heard little change to anything. Then after only a couple days I began to notice a clear improvement of the details within the sound stage. And maybe a bit of softening to the glare in the upper midrange that always bothered me about the Jade 5.
So this neurosis we all have is still driving to look at speakers. Has anyone heard the Gershem Monitors or the LSA 10 signature speakers?
