I said $500.

Any recommendations on what to mod?

Seems like a good value to me.

I'd give it a good while to burn in before modding it. When things are this well-engineered, it usually takes a while for the caps to burn in.

This looks like a really great modding platform, because it has so many outputs. You could do a couple different mods and easily switch between them. Not sure what to recommend in particular; you can try all the classic mods (swap op-amps, bias to class A, upgrade caps, bypass output stage, etc.).

Yeah I'm going to leave it stock for right now.

You have just described my fantasy. Imagine those 4 outputs with a distinct sound each... and I have 4 preamp inputs as destinations for those to go. 2 preamp out to go to two amps. That would be the ULTIMATE! Now I'm excited and cannot go to sleep.

Now that makes is a better bargain than going with multiple soundcards with different mods. Looks like plenty of room for Brown Dog adapters there, Lan.

Heheh, one of my RME PAD's is going under the Iron for an analog bypass and balanced output mod.

Ed, do you have some XLR cables to run to the Grace for the balanced RME?

lan, great pics, I guess I will just have to keep waiting to see what the 1212M sounds like, especially modded

Irons too bad you can't keep the 1212M long to see how it is stock after breakin. It would be good to know it's stock performance for those who can't mod.

Edwood, I can't imagine having 3 PADs in one computer haha.

Well I will give it a good comparison. I think Sdiubek should have given it a decent amount of burnin time, and I will give it at least a day as well.

Three RME's in one box is so old hat, we've done it on numerous occations now

really? where? I see only one 5V reg per ADC and this might even be shared for digital and analog supply.. or digital supply is fed to all converters from one place.. anyway, I can't see any regulators for opamps too, they will most likely share one supply too..

btw. how many volts is it powered with? 24V?


to be honest this is really a sweet baby - five CS4398 with five AK5394 - what more can you ask for?

I believe parts D24, D30, D26, D32, D25, and D31 beside the ADCs are regulators.

probably not, regulators are in five-leaded SOT package, Dxx are regular transistors.. I can't follow the traces, there are lots of vias, not a single continuous trace I still thing they are not power-related..

Why would you expect a single voltage regulator be in a 5-lead package?

12V comes in from outside the box. I don't know where and if that is converted to something else inside.

I've upgraded to using external power. Clarity is increased by quite a bit from using the computer's power supply.

Well... considering Justin's (Headamp.com) reputation for taking a long time to deliver amps, Iron will probably be keeping my EMU for quite a while, hehe.

So I think he'll have plenty of time to RMAA, compare, test, and listen to his heart's content.

Oh yeah, and then he should go out and buy this card (1212M)


***What I REALLY wanna see now is the 1212M versus the 1820M.. I mean i'm quite happy with this card... but a BETTER version of the same card? Kick@$$

Although, as most things I dunno if the increase in quality would justify the extra 300$. Hmm...

I mean part of what makes the 1212M so friggin great is it's good for WDM and Audiophile-grade audio, all for only 200$, and it competes with more expensive cards that ONLY do Pro Audio (i.e. RME PAD)... if you raise the pricetage to 500 it's like raising the Perreaux's price to 500/600... the amp is still the same, but now it has more contenders, yknow?

In any case, i'd like to hear your thoughts on this Lan, because if the potential for modding is as wide as you say, maybe the 1820M really is worth a shot
