HI dawsOn
I did try one and nearly bought one about 13 years ago ,at the time it was the only dac that in my system then bettered my Marantz Cd 94 mk 2. I have tried a Cambridge awhile ago and frankly the Marantz on its own was a lot better. I sold the Cambridge dac on ,i thought it was a bit over rated IMHO. If the Pulsar is cheap enough and in mint full working order its worth a punt and if you don't like it you can always sell it on . If you don't pay a lot you should loose very little,bear in mind e-bay fees(if thats how you sell it on).
The Dac had a nice big open and detailed sound with good dynamics and nice fine detail (compared to my Marantz),but it was not a massive improvement on it. Loss of my job at the time stopped me making this purchase. The Pulasr was a step forward compared to the sound of single bit/bitstream dacs at the time IMHO. I much prefered it to Deltec,Micromega etc.
