+ Amp – That's Mytek's Brooklyn Amp with the new 'plus' suffix. "New faster transistors cut so-called switching dead time to low nanoseconds and there is a faster and higher 650kHz carrier clock. Both contribute to greatly improved low level detail and lower distortion. In addition the output filter frequency is now two times higher." Original Brooklyn Amp owners can have their unit upgraded for $500. 1% THD specs for power delivery are 250wpc into 8Ω and 400wpc into 2Ω. Though the new transistors aren't openly identified, they read like gallium nitride parts which are gaining in popularity with class D circuits from AGD Production to Java Hifi to Merrill. We recently even saw them in Gold Note's small class AB amplifier.
