Comments on Blue Circle Tube Preamps

I've gone right up the line from the BC21 to the AG8000. Literally, I have either owned or test driven everything in between. These preamps cannot be bested by anything at their given price point. BC preamps are just slightly to the warm side of neutral (some are more this way than others - depends on the model). Very good with timbral accuracy, image, bass extension, punch, dynamics, you name it. The Mark II models are a nice refinement of the original products, which were excellent in their own right. If you have a specific model in mind e-mail me, I can provide lots more info.
