Hello again

Researching in the forum i only can read one opnion about this question
I don´t remember who but one person say that the ESP 14 is not a really bridged amp, is how a slave amp but in the page of Linkwitz -Pluto section - the bridge schematic is the same, the only difference is the OPA2134 or the TL072

I´m interested in opinions about this, if there are reasons for one or other way

Hi,
ESP 14 creates a pair of outputs that when connected to a pair of amplifiers produces a bridged amplifier.

Be aware each amplifier, whether chip amp or discrete must be designed to drive a reactive load of half the value of your intended speakers. That equals a lot of real estate in PSU as well as amplifier.
