If you are in the market for a tube based phono preamp where you can tube roll, then you should consider this JD9 MKII from Jolida. This is the improved MK II version which the previous owner was so enamored by it that he went for the full boat upgrade on it – Level 1 to 4 which cost $1,750 (See Jolida’s website on what each level of upgrade entails). It still uses two 12AX7 tubes inside which are offered by every tube manufacturer and are so affordable, you are going to have a field day tube rolling the Jolida. The JD9 MKII also has eight impedance levels on the back where you can select to match your cartridge and three gain switches to select MM low gain output, MC high medium output and MC low high output. Manufacturer suggests using the MC high medium output and that was what we used as it was the more balance among the three. There are two preouts on the back where the LO out is a 200 millivolt output and the HI out is a 1.8 volt output which you can choose depending on the preamp or integrated amp you are using. Some additional specs as follows;
With all these features and flexibility, the JD9 MKII is miles ahead the competition in terms of fine matching your turntable to the rest of your system. Cartridge selection plays a big part in its final sound too so the end result can vary greatly when you add in the tube factor and what brand of tube is installed inside.
Cosmetically, the unit is in very nice shape. Very minor marks from use, nothing major. We don’t have the original box but will securely pack this for safe shipping. Copy of JD9 manual included to help determine the setting value for your respective cartridge. Current pair of tubes installed are Genalex 12AX7. An extra pair of Mullard 12AX7 tubes will be included
