I have said it before and I'll say it once again. I have done a lot of research with guys who actually owned or used many phono stages including the Whest Audio phono stages. They all said nothing came close to the Whest in performance. Then I spent a lot of time reading the customer reviews on the Whest site (hundreds of them); if you read these from guys using all types of phono stages, they all explain how much better the Whest units are against a wide range of competitive units.
From there I studied the internal boards of the Whest and the construction used along with components and I concluded that the Whest was the best option available. I have owned two now and I can say that they are spectacular, especially against some of the 'standard' recommendations spoken of in many of the threads.
I'd skip over most of the ones spoken of and go straight to Whest Audio in London, you will not look back at that decision.
