Yes, I have modified mine. Change the output cap 2.2u to some real good caps like Jensen. Change the Digital Output Cap ( C4) 0.1U to good quality cap. Change the High tension electric cap to a good quality one. Mine is much better the than the CEC origianl D/A.

thx for sharing

There is some brown color 100U 400V, you can replace it with other caps like blackgate or jensen , it will improve significantly, Also change "C4" lablel on pcb ( 0.1U) this is the digital input caps, the effect is very hugh if modified.

yesyes accphoto
i already change the 0.1uF to wima , and those high voltage cap

thanks for ur advice

have u tried to change the resistor next to the high voltage cap to choke???
i heard someone said it will create smoother DC....

alfcat,

I saw a LITE DAC50 at 2nd hand review 33.com. owner asking $980 only.
the sound quite sweet and muscial .
it can produce great sound after some modifcation.

thanks

Viewer 兄,

如用了 DAC, 咁改咗的 Analog 部份就用不著了, 對嗎?

hi alfcat.
ans is yes.
but you can have fun and compare with cd 33 Analogsound stage.

thanks.

I have not change the resistor to choke yet as it will cost quite alot unless you buy local choke..... There is no place in my DAC too as I chnage the high voltage cap to a large Elna 100u 500V x 2 cap.

accphoto,
i have recently change to a choke(lite), but the effect is not very dramatic.....not as dramatic as chanage cap.....

The original Lite tube IV did not sound appealling to me and I have done this Jfet IV modification on Lite 50.It sound much better now.The Jfet IV is based on Nelson Pass D1 IV design with change of mosfet to Jfet.

Add balance output by using Lundahl audio transforner.
