We would recommend looking at a t+a pa 3000 power amplifier
https://www.ta-hifi.de/en/audiosystems/hv-series/a-3000-hv-power-amplifier/
The Pa300 sounds amazing on Wilsons the Pa3000 is a powerful 300-watt powerhouse that can provide ample current for the alexias
The pa 3000 is a remarkable solid-state amplifier that offers a clean high-resolution sound that uncovers all the details in your music but is also exceedingly musical.
The HV series was developed due to research done by T+a in uncovering why tube amplification is so musical and they discovered it was due to high voltage rails driving transistors to sound more linear and warmer.
the Pa 3000 offers a warm sounding midrange yet is fast and detailed and has excellent bass and dynamics
in addition, the amplifier is built to the highest standards of much more expensive gear:
the amp is built on an aluminum frame with sealed compartments which separate the amps input and output stages
the mains transformer is a work of art it is massive 2kv and is potted and shielded
another cool fact is the amplifiers performance can be easily upgraded by adding an external ps3000 power supply this box adds an even larger 2.2 kv transformer used to power the output stages of the amplifier while the internal power supply now powers the input stage exclusively
and you can always add a second Pa3000 to make a full monoblack
when you add it up you can not find a better or more flexible amp to drive your Wilsons that offers world class sound and build quality yet is affordable.
