The Havana is not a bad DAC for the price. It is more detailed than the TDA but on Marco's Tannoy the Sony R1 had a much bigger sound-stage and presence. Bear in mind the Havana costs 800 usd were-as the Sony R1 original cost + 1.5K of Audiocomm mods ?

I personally would not buy one but rather go for the Satch DAC kit or a 2nd hand Copland 289 288 CDP. Anyone heard the latest Satch with tube O/P stage ?
