Hi Alex,

I'm still here. After six months of nearly working every night and weekend I needed a break. But I was back at it last weekend adding some new features to the firmware and testing the new DAC power supply based on the LT1963/1764. I also started assembling the new I/V-Amp2 board, and worked on some new designs.

As far as making my project available, I'm still all for it but after the lackluster response to pricing I obviously have some work to do. I've received some great advice from some forum members so I'm currently working on it. In the meantime if anybody has any questions or advice please feel free to jump in.

Best regards,

Al

I do appreciate your commitment, but after all that time spent it is difficult not to see things through rose tinted glasses.

If you are intent on thinking about the project just commercially then you need to ask yourself some tough questions like-

1/ Who is my target market?
2/ What is my competition?
3/ What extra does my product bring to the table?
4/ Why is my product more expensive and what are the REAL benefits to an audiophile?
5/ What is the lifespan of the design?

I belong to an audio club in Auckland, and it seems like there are 2 types of Hifi nuts, 1st the ones that only buy commercial products and sneer at DIY stuff, and 2nd the DIYers who build as much gear as they can and would rather spend time as opposed to money to get the sound right (I am one of these).

You have not attracted the 1st type of person because
a/ very few people know about your product
b/ it is essentially an unfinished product so is viewed as DIY
c/ it is an unbranded product so has no perceived value for resale.
d/ there is not enough hype (and marketing BS ?) being dished out to make it attractive.

I think you might have turned away the 2nd type because
a/ your prices are very high for DIY.
b/ you have provided very little information showing circuits and design benefits.
c/ you have not offered the product in kit form.
d/ you have more or less said this product is not for DIYers!

For me, your product does seem attractive, but price is a big issue, and availability of seperate items is unclear. For my active 3 way project I need to implement a 6 channel DAC with 3 I2S or SPDIF inputs.
Cost for your setup is DAC/Controller $675, 3x I/V boards $800, SPDIF board $125 = $1575.
Cost for Buffalo DAC is $397 (incl 3 regs), 3x IVY I/V boards $267, 4ch SPDIF board $46.00, input selector kit $16.00 = $726 total.
That is a BIG difference and does not include differences in cost for the main power supplies.

I am not sure how this project came about for you, but it seems that (like many other DIYers) you like doing this design stuff for the 'Fun' of it. I know I have spent dozens of hours of my own time building one off products, just because I like DIY. So why don't you make the boards available at a more reasonable price, treating it as a subsidy for your 'Fun', and at the same time let others enjoy your design. Just my 2c worth.

So I am hopeful you will come up with some more cost effective DIY combos and have boards (complete or otherwise) available seperately at revised prices. Personally I wouldn't leave it too long to figure it out as the ES9018 is only the 'latest and greatest' until the next chip comes along, and that new chip might not be a Sabre.

Regards
Jeremy


PS. If you'd like to send a set of boards down to NZ then I would be happy to evaluate and review them for you.

Hi Jeremy,

Thanks so much for the post. You bring up some really good points. I've been working on some of them including pricing. I'll respond in more detail to some of your points in the coming days since I'm a bit pressed for time this morning. Thanks again.

Best regards,

Al

Hi Everybody,

I know it's been a while but I'm back. I finally got around to purchasing a E-MU 0404 and took some measurements last night off my ES9018 DAC with two DAC boards stacked (8 DACs/Channel) and my I/V-Amp1 board. I did the test using a stock non-modified E-MU.

I've attached a couple THD plots. Each measurement is from the single ended unbalanced outputs of the I/V-Amp1 board. I'll have to buy some cables to check the balanced outputs. The first plot shows THD+N using a 1Khz tone at 0dB (1.0Vrms). The second shows a 1Khz spectrum down to -120dB showing the DACs ability to resolve the tinniest details. I plan on modifying my E-MU to see if I can lower the numbers even more but I can't argue with THD+N at 0.000359.

I'll be provide an update on what else is going on this weekend.

Best regards,

Al

Is that using the USB or the PCIe version of the E-MU 0404?

Great measurements. Lower THD+N than the Benchmark DAC1. I actually wasn't aware that the EM-U 0404 could measure that low.
