I can recommend Audience in Bath
Pretty much as the subject of this thread says really! After sending a few emails back and forth to Audience in Batch I went there yesterday to demo some speakers. Originally I had decided to go to Bath as they seem the closest Neat dealers to me (I am in South Wales). Didnt end up buying the Neat, but I guess thats how it goes.
Helpful and knowledgeable staff, great listening room, and good range of kit in the shop. Cant really ask for any more, I recommend a visit.
