Another vote for K&K and the support Kevin gives to his customers. My phono stage is about 7 years aold and has given no maintenance problems, ever. I have upgraded twice, the last time to near the current Maxxed out stage. I believe older models can not be made into maxxed out ones, the construction is not compatible, but to near the maxxed out one. Not a very scientific description. The latest upgrade was a very big improvement.
I have compared mine to a number of stages, including an attempted blind testing in my house, they are'nt easy to do. The only one to better it, was a Tron phono stage in an all Tron system and that was'nt by much.
