I had been using the Opticis with a battery power supply for my PC given that it was 65 feet from the USB Dac.Today I connected the Opticis to my MacBook Pro with a short Kimber USB cable. I used the Wavelength Crimson DAC.
There is a definite improvement using the Opticis. Without it, I could not get the total power of a big drum on several symphonic recordings. The soundstage increased slightly. A purer midrange and highs resulted with better definition.
The sound of the Crimson is amazing, but I could not understand why it would not deliver the power at the bottom octave. Insert the Opticis, and I'm home again.
