anyone has experience in modifing LITE DAC60???
i wanna improve 'depth os sound' of it............作者: accphoto 時間: 2007-8-29 12:24
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.作者: classicyip 時間: 2007-9-6 07:17
thx a lot ,accphoto
I 've changed the output cap to Mcap
sounds already improve a lot
which high tension caps do u mean ??
coz there are a number of them.....which one is more important??
thx for sharing作者: accphoto 時間: 2007-9-10 14:55
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.作者: classicyip 時間: 2007-9-10 21:45
yesyes accphoto
i already change the 0.1uF to wima , and those high voltage cap
great feel
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....作者: alfcat 時間: 2007-9-10 22:22
How much is the LITE DAC60 now?作者: viewer 時間: 2007-9-11 00:08
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作者: alfcat 時間: 2007-9-11 12:43
Viewer 兄,
如用了 DAC, 咁改咗的 Analog 部份就用不著了, 對嗎?作者: viewer 時間: 2007-9-11 13:57
hi alfcat.
ans is yes.
but you can have fun and compare with cd 33 Analog sound stage.
thanks.作者: accphoto 時間: 2007-9-27 13:46
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.作者: classicyip 時間: 2007-9-27 17:13
accphoto,
i have recently change to a choke(lite), but the effect is not very dramatic.....not as dramatic as chanage cap.....作者: spencerhk 時間: 2007-9-28 21:11
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.

嘩！高手，連輸出級都改埋..........作者: spencerhk 時間: 2007-9-29 11:45
Add balance output by using Lundahl audio transforner.
great feel
