New I2S Off Ramp questions

Steve, why do you think your soon to be released Off Ramp with I2S connection sounds better with the P3a DAC than the S/P DIF connection?

Thanks

There are some technical reasons that explain why it sounds better:

1) The I2S to S/PDIF and S/PDIF to I2S conversions add jitter to the signals because of the added digital stages. These are eliminated with the I2S Off-Ramp.

2) The fact that the clocks are separate with I2S and do not have to be derived from the data reduces jitter.

3) The transformers and coupling capacitors required for S/PDIF are eliminated with I2S. It is direct-coupled.

can you give an indication of what the price is going to be for the 12S off ramp turbo?

First cut, it looks like $850.00, but the labor cost is not firm.

I will also offer a non-Superclock3 version will wil be quite excellent I think for $500. I have a really good oscillator designed onto the board.

PC board going out for fab this week, but long lead-time on parts makes the debut around the first of the new year.
