Drubin, I agree that there would be very little deviation in the Harbeth house sound with different amps. However, there would still be perceptible and appreciable differences. The latest NVA integrated amp I have now has proven this with a more tonally accurate midrange up to the high frequencies compared to the Plinius/ARC. Where the NVA lost to the Plinius is in the bass department with the lack of punch and slam. I can perceive a different sound in both vocals and instruments between both amps. Sound of percussion such as cymbals are quite different between the NVA and Plinius/ARC, and the degree of changes are pretty apparent. On the other hand, voices sound more natural and organic wtih the NVA. All these differences are not really day and night but are easily noticeable to my ears. With all these findings, I am now seeking an alternative amp with all the traits of the NVA but with better control in the bass region and possibly a little bit more here and there.
