正在考虑Jolida朱丽达的300B
Model JD 300B
An offering of a Single Ended Triode (SET) integrated amplifier for your listening pleasure. Cosmetically the unit is finished in white metal (oxidized/sandblasted aluminum). The unit has four inputs and two fixed outputs with 4 and 8 ohm five way speaker taps. One feature not found on many SETs is a remote control. We have found with the volume variability in different CD discs, the remote comes in handy with an 9 watt amp. The unit has high speed soft recovery diodes with german capacitors. Matched with an efficient speaker the clarity of the highs and midrange are matched with the weight in the bottom end. If music is art for your ears, the JD 300B may be your sound painter.
