I started out using this transport with a matching Signature DAC IV and was quite astonished at the amount of resolution the pair delivered. Frankly it’s in another league to the majority of alternatives encountered. The nearest competition I could muster in terms of digital transport was Naim’s UnitiServe via its BNC S/PDIF output; this connection is theoretically not the DAC’s strongest input because of the MSB Pro I2S option, but it delivers a none to shabby result as well. The clocked link gave an advantage in detail terms, but when it came to musicality the division was less clear-cut. When it came to emotional communication, I got the best result by combining the Signature Data CD IV with a Resolution Audio Cantata DAC. This was a killer combination; the sheer data extraction capability of the transport is phenomenal and when combined with a converter of the Cantata’s calibre via Chord Co Sarum TA coax cable, it’s in the premier league.
