I own a stock Jolida with the exception that I replaced the original tubes with new production Mullards. In talking to Jolida, they recommend mods based on the owner knowing the nature of sonic change he/she is seeking I suggest that one own the stock version prior to having it altered. One would then know the what they are looking to gain, and if the desired result was achieved. Tube rolling may achieve the desired result.
Jolida Fusion Preamp
Does anyone have a Jolida Fusion Preamp, or experience with one? The level 1 modification preamp, which is about $2000 I believe, does it perform above its weight? I am just wondering how good this preamp is in it's price point
