Nguyenchiro I actually owned the 450 signature previous to the 750's yes they are quite a bit better overall. The upper bass is much better much more authoritative and the resolution of detail is improved upon also the dynamics are improved too. I previously used a Audio Aero Capitol Mark 2 CD player have upgraded this with the Wadia combination, neither of these sounded what I would call too laid back. your system shows the Bybee line conditioner are your amps plugged into it? Have you tried the system without the conditioner? If amps are plugged into it try plugging them directly into the outlet. Also is your electrical circuit just on one circuit breaker? Amperage its rated for? What's your cabling currently? current preamp is? Wondering if it's the Cary? They have a reputation for being very laid back. oh are you running with the RCA input or balanced? The balanced sounds a little less laid back.
