"Disappointing" is the word I would use overall to describe the darTZeel's measurements. When I measured the first product from this Swiss company, the NHB-108 amplifier that Wes Phillips reviewed in April 2005, which had a very similar measured performance, I wrote that "The NHB-108's measured performance indicates that, with the exception of its slightly bent transfer function, designer Hervé Delétraz has avoided the problem most commonly associated with the absence of the usual overall negative-feedback loop." But like the earlier design, the CTH-8550 hasn't managed to reduce the measured aberrations to the point where I could confidently describe them as inaudible under all circumstances. Which is a shame, given the amplifier's beautiful appearance and versatile user interface.—John Atkinson
