It seemed that Solentgreen had mistaken X-dac for A324.
Judging from the circuit board layouts, both units are very similar. Trivista has beefer power supplies, DSD DAC chip and, of course, the tubes though. It is unfortunate that MF did not use standard 75 ohm coaxial cable for digital signal transmission from the digital input RCA jack to the circuit borad--two loosely twisted wires were used instead. Despite its short length, using shield coaxial cable there reduces the noise floor quite a bit.
Shielding the pulse transformer makes it even better.
