The JA15 is a newer 40 watt, push-pull, ultralinear, class AB mono-block amplifier that offers outstanding sonic performance and terrific value.
Thanks to the oversized Jadis custom transformers, this amp delivers plenty of speed, control and slam. Bass is fast, tuneful and accurate. The JA15s throw a deep wide soundstage and can handle most loudspeakers even those with only moderate efficiency. There is no question these amps sound great. Manual bias, available in unbalanced configuration only. Weight 55 lbs.
