In standard mode the dac1 was trounced by a behringer src slighly modded better psu caps and schottky diodes. When you consider this unit is 8x cheaper than the dac1 ...make you think !

Dear Sir,excuse me but your following words " In standard mode the dac1 was trounced by a behringer src slighly modded better psu caps and schottky diodes " interest me a lot.
I have a Behringer SRC 2496 plain stock.
Could you give me please some more details about these mods ?
I would like to try them myself even if working on a smd PCB is not the easiest task.Thnak you very much indeed.
Kind regards,
Be warned the pcb is very fragile.......replace all electrolytic caps of 10uf with 10uf 35v elna stargets.
swap the four large psu caps with pannasonic fc caps with a slightly higher capacitance don't add more than 50%.
replace the rectifier diodes with 11DQ10's or better.
find the two 10uf caps that are dc blockers after the dac and opamp in the output before the pair of opamps doing balanced duties.
swap these for you fav dc blocker cap ....this cap plays a big roll in he final sound. I used big paper in oils 2uf 400v.
damp the case and crystals
be warned its very difficult to remove components without lifting tiny tracks ...I had to do several bits of rewiring.
sound changes ...the first and most obvious is that you get bass !but along with that you get better dynamics and a clearer sound.
Thank you very much indeed Sir for your extremely kind and valuable reply.
I have a friend who owns a nice desoldering station and can help me in the task.
I am very sad that with the coming of smd devices all these operations are much more difficult to carry out for unexperienced DIYers like me.
I already knew that this unit had some potential.
Your words confirm.
Moreover it is very interesting to get your recommendation of Panasonic FC series and Elna Starget.
I can purchase them through a RS Components shop in my town.Thank you very much again.
Kind regards,beppe
email me if you need any pics of the internals .....
