Thoress gear is built all part to part wired like a work of art. I repaired a Thoress preamp/phono and was impressed with the build (shipping damage). Old school in the very best sort of way.
I also heard the Horning Aristotle with the Tron 300b Signature and that is a special combo. Tron has unmatched resolution and tonal purity in my opinion. The sheer amount of inner detail and realism is arresting. I have never heard another 300b amp sound quite this way. You hear deeply into the performance like a great 2a3 based amp coupled with Tron’s uncanny purity.
