I certainly don't want to contradict a customer praising the product - - - but, if I could phrase this differently: It doesn't take the edge off, it simply never puts an edge ON. Big difference (to me). We don't intend with a modern tube design to artificially warmup, or ease off, or take any edge of any highs. We simply try to let it BE unmolested, and not add any smear, odd harmonics, or IM distortion. I think antique tube preamps often DO take the edge off because they have barely acceptable "speed" in the line stages and thus sound soft. The JM preamps are quite fast and use the MINIMAL number of active devices in the signal chain. Less devices = more clarity.
Sure appreciate the explanation Mark......[8]
