I have not tried the A324 but I own the Trivista, and the X10v3 with power supply, and have borrowed an X DAC v3 off a friend to compare the X bundle with the Trivista. No, the bundle is not the equivalent of the Trivista; and the higher resolution system you have, the more the difference will be apparent. Dynamics, soundstage and liquidity are all better on the Trivista. It can be argued that the X bundle resolution is better but to my ears, it just sound sharper, not better.
Interestingly and unexpectedly, the X10v3 with power supply does bring something to the party when the Trivista output is wired through it in my system. I suspect this may not be the case in all systems though.
Trust this helps.
