My hunch is you can go all in and still beat the price of most audiophool stuff and make it sound better.

It is hard to go into the mosh pit of DAC production. Your prices were really low calculated regarding what you try to achieve, designing a state-of-the-art uncompromised converter unit. Differences on ADC quality are greater by far than they are with DAC quality. But it's exactly these small differences in quality that make huge price differences and are harder to achieve. Getting something that sticks out of the crowd is the niche to fit with a product like this. "Eleven", so to speak. The (good) arguments to buy your product: - better opamp on the ADC input than any product on the market - the best ADC chip on the market - best DAC chip available today - best DAC topology possible - best DAC output opamp on the market - professional looking frontend with LCD parameter UI - professional PCB layout due to your dayjob experience and electrical engineering education - fast development, time-to-market - good availability and shorter estimated delivery times than comparable products - fast response to the customers, good communication skills
From my perspective, Tony is right. Your best marketing argument overall is the uncompromised design at a fair price. There will always be customers for this. Those, who don't care about PCB colour but are looking for the best conversion fidelity technically possible now.
Best regards, Martin

The problem is that after reading countless audiophool websites about DACs and who likes what, it's pretty much a crapshoot to guess what people will complain about. As was brought up before, even if I make it to the best the IC will allow, someone will complain that I didn't use a specific color PCB or something. To that end, I'm going all in. Dual PCM1794As, etc. It's gone way beyond the price/performance balance now, so nobody complain that the DAC upgrade board costs more than the whole ADC/chassis does.. The second you said your all in or are going all out, it made me realize this is the epitome of all converters.

All-in is what I was hoping for. Otherwise, why bother? You want to be known as a producer of "very-best quality stuff for a reasonable price", as opposed to "good quality considering the price". At least I think so, given that you said you were anal about the design in the other thread. By the way, I sure as hell hope you're going with a purple PCB with pink polka dots, it makes all the difference! A built-in Radio Shack digital clock and a $3,000 power cord would also make a world of difference.

Well, I'm thrilled to hear this C, I told 3 audio engineer pals about this project(2 of them very commercially successful)and all three want more details. When I tell them the latest here, they will more than likely jump on board! I'll let u know ASAP 8)

It's possible there might be a SPDIF to ADAT converter, which could take 4 of the stereo converters and bring them into an adat interface. That's the best that I'll be able to do. Multiplexing datastreams is no trivial matter, especially if it'd need some kind of way into a computer. You can do this with a cheap used Alesis AI-4 or even a Lynx Aurora. Are you planning both ADC and DAC in a single rack space? I promise I'm in for both, BTW.

1 box right ? I missed this in the DAC description :
"Single card upgrade to the ADC chassis with ability to be used standalone"
So, one can use AD and DA independently like the 2192!

The ADC and DAC cards will communicate internally really only for the LCD display. The ADC and DAC clocks will be separate as the DAC will generally be used as a slave to the signal coming into it. Using a system clock and retiming data streams is a real nightmare and doesn't serve much of a purpose for most situations. The standalone comment means that the DAC will also have a microcontroller and the LCD display code, so in the future it might be used simply as a DAC only box. Right now the plan is still to offer the ADC first, since that was originally what people wanted. I thought offering a DAC would be a nice addition but it seems folks are clamoring for that now too.

I typed this really long reply to this thread and the damn site logged me out again.
I swear..
Anyway, the long and short of it is that as of this point I will not be adding any more features to the ADC, DAC or chassis designs. They are locked and I'll move ahead with what is already planned.
I regret not being able to make this everything to everybody but it's gotta keep moving along! I'll try to revisit some of the outlying wish list stuff in the future hopefully.

I guess I'm with most others here. Give me the best ADC and DAC available. For me, I need both, so I'll wait until you have both available.

I have a feeling I'll have boards before the chassis is finalized, so having both during the first pilot runs isn't out of the question yet. I thought for sure it'd be kinda slow selling these things, but I might sell the first batch out quickly, which might be a good thing because I'll have some capital to get a larger batch going for the next run, and maybe start getting automated stuffing of the boards kicked off. I'm going to be putting around 6K$ into the build of the first batch, which in the short term is a lot of money to my wallet, but it's not a lot for a pilot run of products. I had hoped that the profit from the first batch would pay to buy the majority of the parts for the second batch, etc, but with the cost increases due to the design complexity increase, that's not likely to happen. I figure it'll be a couple batches of 15-20 before I break even on my own investment and can really increase production, if warranted.
Nothing on the BOM so far has more than a couple weeks of lead time. The chassis might be the long lead time item though. It's still not out of the question that I make them by hand. It's just a few holes and a couple cutouts, and a few standoffs. I could make some jigs that guide a router so it's as simple as buying blank chassis and just running a router through the paces. Aluminum makes that easy to do. My cousin does some silk screen work with clothing, I might see if he can do me some screens for epoxy paint and maybe we could silk the chassis ourselves.
There is a lot of possibility here.

So can u give us the final rundown on what is? Also, I usually select/copy long posts before I enter them for the log out reason u mentioned, then if it happens, just rt click paste 8)

It's pretty much just what we've discussed, the SPDIF-to-ADC/DAC options without wordclock or ADAT out, etc.

I'll take a DAC if you use the ADA4898 opamps and direct couple them. I'd pay extra for those chips. looks like there is 15 peeps on this page if you're doing ^ this(which i hope is the case), i also have my brother interested in a dac, and a few non members interested in both as well.

Silk screening is cool but etching or engraving would be not much more and would be both beautiful and precise.

Don't sell these to cheap. $375 for a high end rackmount AD is very very cheap. Make sure there is enough in it so you can be relaxed about the odd returned/faulty one. Do not under sell yourself. I don't care what it looks like... As long as the board is yellow

I don't care what it looks like... As long as the board is yellow Understood, however customers are fickle. I've dealt with it for a long time. People say they want the best quality, but when it comes time to choose, they'll almost always talk themselves out of absolute quality if something cheaper but relatively high performance comes around. Thus, that's why the DIY road is so enticing to people, as people want top quality, but don't want to pay for it. Also, RM might have issues with production now, but who's to say they will forever? They might ramp up next month and be cheaper than I can produce.. And I can expect most of my would-be customers to jump on the RM bandwagon once again. There are tons of reasons to go all out on a design, but there are only a few reasons to keep prices competitive, and those are the most critical reasons of all. Those reasons are that people will always weight cost vs. performance and the average buyer will always find the middle ground. I'm hearing from folks who are very concerned about quality, which I understand completely, but it's the other folks that I'm concerned about, the folks that haven't spoken up, the folks that have yet to know this will exist and don't care about absolute quality. Those are the folks that care about quality, as long as it's within their price range.

No disagreement on your design. Just make sure you have enough fat/profit on each item. $375 is very cheap there is nothing I can find that comes close.. I can see a big market for a transparent convertor to go behind Slates virtual microphone they are no longer doing the DA just the preamp. Alot of home studios do not have the ability to isolate their pres from their convertors your AD would be the perfect solution (probably doesn’t have to be rackmounted).
What ever you choose to do I will buy one..
