Has PS Audio ever specified which Marantz transport they use in their PST ($6500USD)?
The Maramtz SACD 30N ($2999 USD) uses the SACD-M3L transport. The Marantz SA-10 ($7499USD) uses the SACD-M3 transporrt. Maratz makes more than one model reference transport.
The whole cost of the transport analogy seems unusefull though. There is a lot more technology in a player and/or standalone transport the just the transport drive unit. It would be like saying a $10,000 tower speaker is over priced because it uses the same tweeter, and in most cases mid-range driver, as a $2000 bookshelf speaker in the same series of speakers made by the same speaker manufacturer. Speaker companies regularly do this!
