purchasing any of the recommended transports above will only give you a different flavor. Funny thing is that we repair and upgrade components as well as manufacturer our own components. I upgraded the Cary you own for a customer (100 power supply caps, etc.) and we were amazed how awesome the player became. It came close to sounding like the DHT DAC we made. I was so impressed, I bought one and modified one for my personal use.
The upgrade was not for the transport but I would imagine that we could upgrade that to make that unit sound better also.
Keep what you have until you can directly compare something ese.
Happy Listening.
