I have a oppo 205 and it ES9038PRO DAC chip is not too hot. So may be there are something wrong with the LKS 004 ?

For the last few days i tried the Dexa New ClassD opamps and found out it sound very accurate. The Burson V5D have sweeter sound but i like the Dexa more.

I am staying with my MH-DA003. And i dont believe the new DA004 can have better sound than my "modded" DA003. Unless the new 9038pro DAC that fix the heat isssue in the DA004 orthewise there are no chance i choice the DA004

Thank you boob. I will do it :)

About using Burson V5D opamps in LKS DAC. Here are the answer from Burson : So i am safe to use the V5D now. Thank you Burson.

Did you do that to your DAC ? if you do, please take a picture so i can do it easier ! :p Great thanks !

In the last few weeks i heared alot of good things about R2R DAC, especial a Holo Spring DAC. I was very intersting in Holo Level2 DAC and thought gonna buy one to replace my LKS Dual ES9018 DAC and i am very lucky that my friend have one Holo Level2 and yesterday he bring it to my house to let...

I am using the V5i, okay, i will email bruson :P

 My left RCA is 0.4mV , right RCA is 1.5mV. So is it safe to put the V5D in ? I already burned the V5D  one time so i don't want to burn it again :D  It may not get warranty this time !

Thank you. I check those volt when music player it all around 1mV . But i tried all the way and could not trim the volt between pin 2-3  in left channel to 1mV, it is now 2.5mV . is it ok ? I also check the pin 4- GRD and 8-GRD, it all around 14.9V .    BTW, did you put your V5D to the DAC...

   So did you manage to use the V5D ? Please let me know if it safe to use now. My XLR pin 1-2, 1-3, 2-3 now are arround 1mV only. 

Thank you!  So which company (or person) that made this DAC ? 

  Thank you !  BTW, those Holo DAC made from China , right ?

i am intersting in this Holo Audio Spring R2R, i wonder where we can get best price for the basic version ? And how much it cost for upgrade the Silver O-Type transformer ?

  Thank you Bobb, It 30volt now. I trim up the 2 pot near heatsink, each pot up 2.5V to add up from 25v to 30v. Is it right?   The volt between XLR 1-2 , 1-3, 2-3 now arround 1mv, is it ok ?   I'v bouht a new dexa opamps and it will delivery in arround 2weeks, how do you compare the dexa...

Do you mean that the volt between pin 4-8 of the Ticha should be 15V ? But i trim all the bluepot near the heatsink it still show 25v :(

So how many volt should be good for the Ticha? 

      Thank you Tomus4 and mr Great b0bb ,   With your help, i managed to trim down the XLR 1-2, 1-3, 2-3 to 0.9mV  About the volt between pin 4-8 of opamps, i turn all the way of 2 trimpot near the heatsink untill i hear "click" in the trimpot but it only can turn the volt to 25volt...

  Thank you. 8+ and 4- of mine show 31 volt. i XLR 1-2 1-3 and 2-3  show arround 225-226mv (left and right same)   Do you think there are normal?

Hi,   I  take out the opa and measure between the pin 4(-)  and pin 7 (+) in the board opa socket ,it show 16.8volt. is it right ?   Thank you!

  Hi Tomus4,   why you can have 14.9 volt in the board supply volt ? Mine is 16.8 or 17volt :(  Yes my V5D has damge 1 time in the left channel too. I am using V5i now and it work well. But the V5D better than the V5i alot so i do really want to use V5D.

Dear Boob, I guess the main reason that we could not use V5D in this LKS DAC because the board have 17 near 18volt input the opamps, but the V5D only work at 15volt max. So are there anyway to fix this? Can we mod the board so it will supply only 13volt to the opamps?

  You are alway very helpfull :p Thank you !

Hi friend ! I tried 2 trimpots near the Ticha opamps.

Hi B0bb,  Are there anyway to reduce the supply voltage for the opamps in the output stage ? I tried 2 blue trimpot but it doesn't work.
