If this Nakamichi amp is still available I would buy it... Its 100% a ZED amp and very under rated. This amp is in the same class as the best ZED amps he has ever made such as ESX. It uses top grade materials for resistors caps and transistor op-amps , torode. Its a serious quality amp with great power. Its 100 x 2 at 4 ohms with 0.09 THD so what that really means is double at 1%thd which is how amps are set up gain wise in cars. It can easily do 200 x 2 at 2ohm stereo and 400 4 ohm mono... thats just rated with 12v
Its a regulated power supply so it will do rated at 10.5v but will not increase watts at 14.4. It stays steady as voltage swings...
Zed stated once that these are one of the most technologically advanced amps similar to his holy grail ESX.
There is some confusion about rated power as NAK produced a china version a few years after zed stopped building NAK amps that had the same model number PA1002 BUT this amp was actually 50x2 and 200x1 mono flat out. This silver amp and the black pa1002 are in no way related.
I own NAK PA1002 silver and a PA504 multi channel and these are pure SQ but made great clean power that can stand up to anything you put them through...
Zed HAS been quoted saying the silver PA1002 that he built will do 525 x1 at 4 ohms with the right volts/current...
Also its important to know that there is lots of thermo and short circuit protection, dc speaker out, high and low volt protect , clip protect among other fail safes. This am has lots of good tech. Crossover boards are also very well built as is the preamp section with very high S/N and low cross talk and separation.
These amps were the choice of many IASCA SQ cars and builders as they were the best sounding and power houses and very under rated to get into the IASCA classes with ease. Its not an amp that will do min wattage at 12v then quadruple at 14.4 volts. So ZED made the amp super THD FREE to get low wattage output at 12v.
***be advised there is not fuse on the amp so fuse close to the amp.
just cause its a SQL doesn’t mean it can push serious knock the trunk of your Neon BUBBLE with 28” dayton wire wheels..
