Certainly not in those 69cent rotary switches....
Dont want to bash this but as a customer who actually bought these...at least i am really enjoying the sound - need to switch off the tech in me.
The iron...but mostely you pay for the brain and knowledge behind the design ;-). A most forgotten thing these days of DYI where people dont have to think much themselv..but just copy and build.

there is something to it but i roughly calculated the cost of these things, if i hire the most expensive custom transformer guy in germany and get the cases done by a professional shop and all im still WELL under 1k each...USING QUALITY PARTS!!

sure you gotta design something like this but honestly there is close to nothing you cant learn about tube circuits thats not been written before 1940.

you cannot reinvent the wheel.

Audient Centro Master Section Monitor Controller

Just recently put this in my mastering studio. There are so many mixed reviews on this monitor controller I thought I would crack it open and take a peek.

But there ARE examples of successful "hobby builders in their own house". There are people who make well-known and well-regarded microphone preamp products in their house, and even microphones. The internet and direct sales are what permit this kind of business model to be viable today where it wasn't even in our parents' era. I am thinking of examples in North America as well as in Europe. And ordering parts directly from suppliers in Asia is no big deal anymore. I have frequently seen better delivery times from Hong Kong to Portland, OR USA than from California.

Here's a custom XLR Patchbay I built for myself out of Mogami Quad cable.
It's a first time thing for me. Fun, but DAMN it required a lot of wire stripping.

Nice job on the EZ. One of the prettiest boards I have seen. Even the WIMAs are ordered from smaller to larger. Put a clear top on that one!

collin indeed made one the the best looking boards I have ever seen, all caps, transistors, regulators, face the same way, the gain stages and inverting sections, well everything clearly labeled on the silkscreen, the greyhill switches on resistors on the board, not all that work on the switch, the way the input transformers mount on headers....pretty cool stuff.

suppose my only wish on this pcb would be a few wider cap holes, i followed neves cap choices and could not in a few areas, also the unterminated or 600 holm termination area to have a few holes to run to a switch would be nice, i hacked it in, red and black twisted wires heading aft..
pretty minor stuff ...still the best pcb work I have ever seen..


they sound killer and look great in the rack too....

Hi,
I like mine, but had to open it also, because i'm having troubles with my PSU (i assume) - the audiofire does usually boot up only on 2-5th attempt of turning it on.

You write that it's "off the shelf PB2515" - on which shelf can i found it?
Writing PB2515 power supply into google didn't give me any reasonable results.
I would need to find the PSU replacement. Probably the same would be just fine for now (later i'll perhaps try replacing with linear psu outside the rack unit)

opps my mistake it is a "Mean Well PD-2515" http://ca.mouser.com/ProductDetail/M...wj6pKOH0Z1PQ==

Looks to be a cheap switching dual channel +15 -15v DC supply. Should be pretty easy to replace or change with a nice linear one. It draws as much power as a fart, which is evidenced by the tiny amount of passives and one SoC. Not much to it.

Yea mine did that too, a couple of power ons and it would be okay. Just I ignored it for so long that now it simply does not start anymore. I probed its outputs and it seems to still be providing +15-15 but no current draw. I assume it's because the output is too noisy for the digital stuff to start so it doesn't.

lain2097: thanks a lot!! ordered a new psu. you probably just saved my audiofire.
Yes, I also noticed that it gives +-15v even when it doesn't boot up correctly. Perhaps it's because the PSU doesn't start up fast enough or does something weird during the start up... (measured only using multimeter / don't have an osciloscope to monitor what exactly is going on...).

When it will again work as it should , then i'll try compare (measure) how it sounds sound with PWM psu versus linear psu. I am not sure if it's such a big deal in practice.

How is it that we Slutz think we are smarter than EchoAudio who can sell likely thousands of products like the AudioFire 12 to presumably sophisticated and discriminating audiophile customers with switching power supplies which are so widely condemned in these forums?

Yes, I packed that all into one sentence!

@Richard Crowley

Don't know if you're being sarcastic or not but I never said there's anything wrong with well designed switching supplies, even Apogee and probably many others do as well. Every piece of high end highly reliable (100k+) networking I've seen uses switching supplies.

Other than that supply it seems well made especially considering the price for 12x12. Hasn't stopped Echo from moving product; I enjoyed using it and the results.

If something is built to a price and is 1/2 or less than a competitor well something has to be compromised.

In a weird way it was time to upgrade anyway.
