Hi Tan,Burson replied me that they are out of stock now. I was told by other that this Opamp was not actually made by Burson, it was orginally made by a China company but has stop the production now. Burson has bought all the remaining stocks at that time.Not sure if it is true or not but in case there is no more Burson Opamp. Would BB627 the best alternative. What will you recommend?RgdsAndis
Hi Nic,How do you compare the Burson Opamp with your stock 5534?In case I want the Burson Opamp, can you test for me which value of the bypass cap give the best performance and solder it for me. (Will send you an email when confirm)Tks & RgdsAndis
I check out the burson buffer posting of yours and would like to comment that our DAC allows up to +14.5Volts to -14.5 Volts. You would need to turn the potentiometer clockwise to turn up the voltage Also the maximum voltage may not be fully regulated if your wall drops below 118Volts. To measure place the probe of the multimeter at pin 4 and pin7Pin4 is the minus voltagepin7 is the positive voltage
I liked the dac when it was working.After numerous emails to Nicholas in six weeks and being told there was a new dac board on the way,nothing yet.Very frustrating.
Nick,I got it. But somehow I could not adjust equally pin7 between two channels of Burson Opamps. However, I like the sound in between 11.30V to 12.5VDC. Thanks for your help.Tan
Hi everyone,I just received my DAC from Nic a few days ago, its the latest version, silver pulse, silver RCA. Out of box, it sounded wonderful especially the bass but treble a bit coarse/hard - need time to burn in more. My only complaint so far is in the LEDs (looks only) - too big/bright and colour choice. It was RED and GREEN. I changed them to smaller ORANGE and BLUE and added resistors to dim them.Now for my question : how and where to place the feet/footings under the DAC to bring out its best?Since the DAC comes without any feet whatsoever, can anyone share their experience/experiment on the subject? Cones, which is better wood or metal? Hard, soft or heavy/light wood? Orientation - pointed tip up or down? Location of cones? Placing them directly under the 3 trans? Thank you
