That's why he's using a huge cooling system as bottomplate, to dissapate the heat of the transistors/mosfets. I am baffled as to why he is using active cooling in that particular place, since the transistors are not even close to the cooling system. Ah, i see, the fan sits there to actively cool the massive bottom heatsink. it was much betetr to put 2 cooling fans above the 2 x2 parallel transistors/mosfets. Direct, active cooling has huge impact on sound.
I would change the white caps for oils or teflon caps, they are in parallel. It will considderably improve sound quality.
powersection looks very decent though, i see elna cerafine's and black gates? Overall very decent.
If the amp is biased in class a, you would have at least 8-10 watts of pure class a power; with high efficiency speakers say above 90db, you could have a nice rig.

SXT2 is in Class-A, the heatsink is become warm(not hot) last night.
The caps are Silmic and LPO.

How can we go about making this thing available to the HeadFi crowd without jumping through a ton of hoops?
edit : too everyone that is concerned about the noise of the fan, if it is loud, I'm sure it could be replaced with a top of then line unit relatively easy.

Sorry, it's brand new one.
I will write a short review later, but English is a pain to me.

Under the fan did not hide anything. You may see the PCB.

according to this thread by the creator of this amp on :
http://www.erji.net/read.php?tid=126...toread=&page=1
it seem like it's a one man company. to order people have to line up in
the queue, and even their order are accepted, the waiting period is 2 months.
i just pm the designer, asking if he can ship oversea to australia

Oversea order isn't the problem, but you need patience to waiting for.
The designer甩袖湯 will finish every SXT-2 by himself.
