LampizatOr- BEST300B  DAC Manual

3. Why R2R conversion? 

From 2014 we observe that the top 5 DAC companies in the world use R2R discrete 
ladders as their top solutions. These solutions go up to 100 000 Dollars for a DAC or even 
more. Therefore we co- developed our own R2R solution and we offered it in our Golden 
Gate DAC. BEST300B project is about bringing this superb and superior converter type 
DOWN IN PRICE POINT to be accessible by the majority of audiophiles.  

4. Why Copper capacitors? 

Since there are only 3 components in total in our signal path - it is important to use these 3 
parts from the highest quality group. the output capacitor is one of the three so we wanted 
to use the best available at any price. So here it is - our Lampizator house branded copper 
cap which matches the 4 known copper brands in quality of sound.  

5. Why do you claim this to be one of the best DACs ever? 

Well, the above explanations sum up to the statement - that the BEST300B is the only 
known DAC that combines R2R discrete ladder conversion, Directly Heated triode tube 
output, copper capacitors (with real Cu foil versus the metal vaporised plastic) and last but 
not least 10 years of Lampizator’s expertise in DAC design and technology. Add to it the 
DSD capability and excellent test / purchase / warranty /policy and you get as a package 
one of the best DAC in the world.
