I was cautioned by more than one person about software glitches and lock ups with the D100 while researching. An interesting question is which company did the primary development work on the D100 and its twin, McIntosh or Wadia?
It's still an attractive product in many ways and has the right feature set for the most part, not very many products are really getting the digital pre amp thing right. I feel like more companies are taking a stab at the whole pre-amp capability for DACs more as an excuse to add another bullet to their marketing sheet rather than have the product be capable of actually fulfilling that role without compromise. The D100 feels like it was designed to be a pre-amp from the beginning rather than just a DAC, and it shows.
I'm particularly amazed that so few of today's DAC/pres have 12V trigger out ability, this should be a given on anything calling itself a pre-amp but I find this feature missing in most of the products I have looked at.
I fully agree. Most DAC/preamps seem to be half baked. I heard the D100 drive a couple 1.2kW McIntosh mono blocks with B&W 802 Di speakers and I had to say it was the best I've heard those speakers sounding so far. Whether that is down due to the mono blocks or the preamp I can't say, but the D100 certainly didn't seem to detract anything from the performance. My Hi-fi dealer suggested I save up for the D100 as I told them I was looking for a dedicated DAC and that I listened to headphones.
I also believe I read somewhere that Centrance was involved, but I'm not sure whether it was only for their USB implementation?
Honestly for a digital only based audio system, the D100 is an ideal starting for a very capable setup. Its a pity the headphone amplifier is not really in the same league.
