Music Hall 25.3 DAC & headphone jack with PcX upgrades - clock, power supply, balanced output and more
Bought new from Parts Connexxion in Canada recently. They also carried out the upgrades - they know what they are doing as this is a standard service for them as well as being the founders of the original Anthem and Sonic Frontiers brands.
I bought this unit to use the balanced outputs. As such, output upgrades are on the solid state balanced section of the dac and not the single ended tube output.
However the power supply, clock and input upgrades benefit either the tube, solid state or headphone jack output options.
Volume pot only controls the headphone jack.

Upgrades:
Input IEC now a Furutech Gold type
Key electrolytic capacitors upgraded to Nichicon KA, FG types
Voltage regulators upgraded to Dexa UWB Series types
Dexa Special Edition opamp upgrades
Bespoke built bridge rectifiers (see photos)
Key resistor upgrades to Takman REX and Vishay Z-Foil naked types
Big clock upgrade to a Dexa D-Clock Neutrino 2 (these are the new latest types)
RCA digital input now a WBT true 75 ohm compliant type with a 75ohm Illuminati wire kit to the dac board (to maintain true 75 ohm)
This was an expensive dac as the result.
Selling as a house move 3 weeks ago means I’m rejigging my hifi set up to smaller footprint components.
This is a sad sell as I never got to use it much, no more than 50 hours use so still burning in.
£600 including UK post.
