Ronnie, your gears are really great.
Will you have time on this Sat to review the UCD180? We can also discuss how we proceed with your UCD700 like the case selection and whether to make it mono block or 2 channels in a box

My very first module was 0024. I think my module (UVD400) was indeed number 24 on this world!
The sound of UCD is very powerful but a bit dry. To me, it is good in dynamic and details, spacial separation. I am using my DIY GG as a preamp to give it just a touch of coloration.
I think i will try UCD700 soon!
BTW, there is a UCD modification thread on www.diyaudio! May be we can start our own thread in HK soon!作者: admin 時間: 2006-5-8 19:26
Hi ackcheng, Yes, we are going to make UCD more famous in HK
After the initial test, all people feel UCD's bass is very good and the sound is really clear.
Also there are a lots of potential in UCD modifications, please share yours if you have done.
Will you be available tomorrow night or on the coming Sat to share your UCD experience with us as well?作者: Kelvin1728 時間: 2006-5-8 21:11
大家好! 小弟初哥一名, 想請問UCD180/400可用在AV方面嗎?效果ok? Thanks a lot in advance.作者: ackcheng 時間: 2006-5-8 21:56
Thanks! I am afraid i cannot come tomorrow! I haven't done modification on my UCD, However, I have tried different caps. Initially I used RIFA 10,000uF. But the bass is not good enough, BHC is better. I may try Sikorel later, but they are very expensive!
One thing is that I think we need to use oversize transformer. I have 400VA transformer for UCD400 which is supposed to output 200W at 8 ohms. However, I could only get 150W before clipping occurs.....作者: ackcheng 時間: 2006-5-8 21:57
Actually, i am planning to build a home theatre system using UCD 180. For AV, i think it is a very very good choice.作者: Kelvin1728 時間: 2006-5-8 23:17

hi ackcheng hing,
I've just set up my very first home theatre system but found that sound field is too soft and details not clear enough with my AV amp. I want to add a post-amp for the 3 front channels and would like to ask for your advice on the following regarding UCD180 module:
1) Since I'm using 8-ohms speakers, do you think UCD180 is powerful enough to drive them as output would actually drop to 90W on 8 ohms.作者: admin 時間: 2006-5-9 00:57
Kelvin1728, ackcheng,
We'll also setup the DVD and AV amp to test the power of UCD (for front channel) tomorrow, welcome to join if you have time

Thanks for your kind invitation!
I have been using UCD400 and there is plenty of power! I think UCD180 is OK as well. One things is that it has very low output impedance so the damping factor should be quite high!作者: sunsvc 時間: 2006-5-10 21:10
Great, you guys are making a difference.作者: Kelvin1728 時間: 2006-5-13 22:46
Would those big brothers who attended the latest demostration share their opinions on the use of UCD180 for AV purpose. Thx a lot 作者: louisla 時間: 2006-5-13 23:46

UCD180,400,700是已砌好的, 只是電源部份PCB是散件.
