The Jolida JD-9A MK2 is a very good $650.00 phono stage. It has a tubed output stage and rear panel controls for cartridge adjustment. It has enough gain to run almost all moving magnet and moving coil phono stages. Our Level-1 mod takes it to the next level and allows it to compete with phono stages that sell for up to $1500. The mod was designed by Chris Johnson, the founder and former president of Sonic Frontiers. The modified unit comes with the full Jolida factory warranty.
