This is the stereo version for the Dual mono MDA-400.

SDA/MDA Gain Modify

Hi,
I thought it may be useful to others.
Honestly, the SDA / MDA have the input sensitivity already in the standard range.

Attention, with a normal soldering iron there is a risk of destroying the pads.
Use two welders equal to the res smd desolder.
Make sure that during welding, the amp is totally disconnected from any connection, including gnd.
This change does not require calibration.
Change two res same value, eg. 2x15K.
partial scheme coming soon

Dimensions are referred to an MDA-400 complete.
I am waiting for a case for this amplifier, use this panel at rear.
Front 10mm thick, with very nice top / bottom cover 6 opaque pastel colors.

Rear Panel, includes wrong RCA-Input (I not use this,just on old photo), then changed with professional CN, certificate gold.

Hi,
these kits look interesting.
Is there any listening results? what are differences with IRS2092? NCore ?

Welcome aboard, I can describe technically, the impressions of listening, it is fair to say that those who have in the house.
Mature project "commercial", complete with some functions, such as the finished High Fidelity product.
Only 3 releases since 2005.
Materials / components and the engineering of the pcb, I think it is visible.

My disinterested opinion (if accepted),
Not recognizable as Class D in any condition. supreme female voice warm up to full power, richly detailed in the high spectrum..quiet as Class A-B amps. :)

Thx AP2,
Technically, the boards look quite impressive : the quality of the components looks amazing.
This is why it is so important to have user review to know excatly what is the final result.

But
I was desapointed many times with class D sound.
I really want to try your amp, but without user reviews, it is a risk.
As I am in Paris, do you know someone in Paris who already have this amp? Maybe I/we can write a user review?

I agree about the reviews,as said, but... would someone explain to me how it is possible that many amp full of good or nice review, I listened and launched out the window?
Maybe I'm not good at recognizing a good amp?
Or some companies, knows who you are buying based on reviews.:p
my advice is.. to trust only yourself.
