LFD DAC3: A delighted customer and three questions

Dear Howard. I am wondering what the light that says “DEM” indicates (beneath the mute light)? If a copy of a manual can be obtained by email that’s of interest but I understand if it’s not available.

Hi Howard I am considering a Dac5 as a wedding gift for someone. Do you have a sense of its effectiveness connected to a computer or streaming device? I would need a USB converter I know. Or is there a possibility of another Dac that might fit the bill better. I am also considering a Read More →

LFD AUDIO: DAC3 and why it’s best to check

Hi Howard. I write from the US. Just about to purchase a LE MK IV Signature and a pair of Harbeth P3ESR’s. Hoping you can recommend a DAC that would work best with this setup. All music will be coming from a computer with the files saved in JRiver. Since the DAC 5 isn’t available Read More →
