Yep, there is most definitely a problem with my C2..I know this is a C1 thread ...hope no one minds.... The volume level has to be turned up way too far for it to get as loud as it should and I bought a 40.00 tube 12V pre amp off ePay and it sounds much better that the C2...Something is wrong, very wrong. I have tried everything I know to figure it out and still no luck. I know this pre amp should run circles around a dOUK aUDIO 40.00 Pre. I wish it would be something like change two caps...I am sick of going into it so I have all but decided to just leave it alone...Lee Audio..Aurex.. Can I send it to you so you can check it out for me or can you guys at least point me in the right direction..
