带T的据厂家说还是要好一些的,看这一段:
Users might expect slightly improved sonics with the Sony transport, which is said to have lower levels of digital distortion called jitter. So look for the "T" in the serial number for the latest and best from Arcam. The CD62T arrived belatedly as the entry-level DiVA, pushing the CD72T to mid-DiVA behind the top-of-the-line CD92T. The new CD62T and CD72T ($899) share the Sony transport and a 24-bit Delta/Sigma digital-to-analog converter.
