Fair...the K&K Vinyl One was not built quite to the same standard as the UK built Vinyl Reference.
The circuit is better on the Vinyl One but was made using less expensive parts to hit a more appealing price point.
The parts on the Vinyl Reference are going to be better as there was less of a focus on keeping costs down. Even the face plate on UK based models are better quality made by Sheffield Steel which was known for extremely high quality steel production.
Ultimately, when all production went back to the UK, Tom scrapped the Vinyl Reference and used the superior circuit with superior parts. This is a big part of the reason the price has gone up.
I have the Vinyl One Copper Reference and it is built like a tank.
