I have a PS Audio Perfect Wave Memory Player, which I was able to acquire for a very reasonable cost as a used sale item.
I was quite new to Digital as Source when this Transport was purchased, and can't say how it performs in comparison to other Transports of the reputation discussed in this Thread.
A HiFi Dealership is based approx' 20 miles from my home, who as part of their product line, offers Jay's Audio Transports. I have been tempted on a few occasions to pursue the experience of Jay's Transports but do not see myself as a buyer, so did not want to Tyre Kick. Maybe I should be more open minded and present myself as potential future customer, the impression made from the experience might just create such a mindset.
As for the PW Transport, there is plenty of guidance that is discoverable, that directs an individual to successfully exchange the Transports CD Drive as a DIY Task. Spare CD Drives can be bought for back up for reasonable monies.
