I should have included some more info. I have a Classe' Four pre-amp and it's phono stage is ok. I know I can do better. It was better than average with my older cartridge a Stanton 881S. I then purchased a Linn Lp12 and as part of the deal it came with a Troika cartridge. The Classe' with 62db of gain just barely produces enough volume to be satisfying. I also have heard the Troika sound much better.
I had planned to replace the pre-amp but somewhere along the line I realised that it really wasn't the pre-amp at fault just it's phono stage.
The Troika has a very low out put(.1Mv) and it makes finding a phono stage that much more difficult. If I had an unlimited it would have been easy unfortunatly I don't.
The PS Audio GCPH offers lots of gain, selectable loading, the ability to run it directly to the amp, a fair price, and is available in Canada.
Really the biggest drawback is me. I have to research things to death.I won't be happy until I've heard from all of you, once I have considered your opinions and checked out the products that move you then I can buy in confidence.
