Hi Lee,
Havana is truly a quality DAC(great price!!), I have no intention to sell it at all. If you are not familiar with NOS DAC's presetation, Havana gives you a very raw kind of sound. It reproduces the most organic timbre i've ever heard(I think it takes at least 2k cdp to beat Havana in this aspect). The sound become so much more alive and present and there's never any moment I heard anything harsh, silky violin sound etc. For example, the sort of drum snare sound you get from Havana is just delicious, great on vocals and accoustic stuff, though I've not yet written it off for rock and pop stuff cuz it's influenced by my CEC cdp, which gives pretty laid back presentation.
I think that's what brought me to the point where I decided to get a forward sounding cdp, hopfully one notch higher than CEC with much better bass, to give a better balance.
Anyway, highly recommend to give Havana a listen, it made me wonder if a cheap NOS dac can sound this good, imagine another NonOverSampling DAC by Audio Note, costing more than double the price, it's just pure music!! But if you are into analytical stuff, than you might find it mediocre and smooth sounding.
