Yup, it has its own amp, and it is very high quality, perhaps a bit too lively and dynamic.
The line out connector is 5 pin DIN, and really it isn't good enough quality, you do notice the differance when you take the line output through another amp of similar power to the 2000K own amp. This is just down to the leads and connectors.
If the connectors are cleaned and good quality leads are used, along with a good amp that has good quality input connectors then you will be impressed.
These machines at the time cost as much as a decent secondhand car.
