Since the speakers arrived, I have set them up with my 300B amp; the first impression is the sound stage is wide, deep, and high, which was exceeded my expectations. After some minor placement adjustments, I am settling down for now and just play the music to let the speakers having some time to break-in before I make any further adjustments.
To make a quick first impression, I would say this new speaker has been a lot of enjoyment to listen, they are very smooth and creamy sounding, and the detail retrieval abilities are great. With these combinations, they image and focus great. Once I am done with the project in the next two months, I will spend some quality time to do some more tuning with the amp to further improve the speaker matching. Now I can only imaging what would the speaker sound like once they are fully broke-in.
