Empirical Off-Ramp I2S/Freeway I2S products now available

This is our first custom-design circuit-board product. It converts USB to I2S, the native DAC chip interface. The I2S outperforms the Off-Ramp Turbo, and it is no slouch. You must have either a Perpetual Tech P-3A DAC or a Northstar 192 to use it. The I2S interface eliminates all of the jitter created by S/PDIF. Lowest jitter solution that we have heard.

Please see the website for more details.

Also, we have plans and are actively designing an I2S solution for the Benchmark DAC-1. This should be available in about 2 months. We have a new DAC-1 to model the change already and many of the parts. The Off-Ramp I2S/DAC-1 combo should safely outperform practically everything on the market.

I'm enjoying the heck out of my I2s/P3a combo. How much better do you anticipate the Dac1 to be over the modded P3a?

They are both wonderful. I think the newer DAC chip in the DAC-1 may give it the edge in 3-dimensionality based upon comparisons with the Off-Ramp Turbo. I would give it 10-15%, but I will not know until I build one. The advantage of the P-3A is that it uses fewer op-amps, and an external power supply. Gets the magnetic field away from the circuits.
