Default ZCA 5 watt mosfet amp

Good day,

anybody out there tried this single mosfet amp? If so, how do you compare this with the HIRAGA or JLH? It just caught my curiosity.

Many thanks in advance.

Default ZCA 5w class A mosfet amp

I just had a glimpse of the project at Mark Houston's site, its a single mosfet amp, a lot of DIYers already built this, some posted their pics, power aside, can it be comparable to a HIRAGA or a JLH?

I'm planning to build one

regards,

efren

Default well ....

it is a very nice amplifier .... but power is so low ....that is actually doesnt worth to bulit it ....

it can makeeven cr**py speakers sound amazing
with extra super sensistive and efficient speakers you might be able to have a bearly listening system for every day casual listening

be advised ....the zca is the ultimate energy killer ....it will produce a hell of a lot of heat and consume serious ammounts of energy just to produce a few watts ]

Default This one?


I do not think goes to 5 watts...will be distorting a lot.

There are a growing number of situations where 5W is sufficient... my main amps are 3.8W.
