My apologies, I have used the Peerrless unit with a KEF B200 in 1975. I liked it. It was clean and I regret selling them. Compared to the Kef it was more efficient. I've got a theory about domes. I think that they often have an issue at a frequency equivalent to the wavelength that equals their diameter. That last sentence probably hasn't come out too clearly. What I mean is that 1" dome often profit from a notch filter at 13k, 19mm domes at an appropriate higher frequency and 38mm domes nearer 10k. You'll see a bit of a bump in the Peerless response. Martin Colloms in the more recent editions of his great work on speakers suggests such a notch filter. It takes out the sibilance and some of the things that people react to in the high frequency range.
