2008多項課程召集 - (6) UCD 後級製作班 (仍可享舊價優惠) 已完結

Cyrus,

You can listen to the UCD400AD on the coming Sat when you completed your preamp.

請問幾時可以試聽UCD180ST 兩聲道，最好係星期六？
如果試聽完唔合心水，可否取消課程？
回覆可否用中文？

Is this demo in coming Sat (1-Mar-08) opened to public or just for the students of pre-amp class?
How is about Vincent's (ref: 11:27 am dated 14-2-08) suggested demo in 8-Mar-08?

Hi HiFiFever,

UcD180HG-HXR 模組            x2pcs
UcD Supply HG Mono 電源組件   x2pcs
Transformer 變壓器             x2pcs
Mono Block 機箱                x2pcs
RCA connector, Output Connector, cable, Switch and all basic 配件.

William san,

hpq,

UcD180HG-HXR 模組 x2pcs
UCD compatible Power Supply 電源組件 x2pcs
Transformer 變壓器 x2pcs
機箱 (for Dual Mono) x 1pcs
RCA connector, Output Connector, cable, Switch and all basic 配件.


Dual mono means 2 channels put in a chassis with totally seperated power supply, input & output.

It is a mathematical course. Please note the following equation:

Total cost (HK$): X1 + X2 + X3 + X4 + X5 + X6 = HK$ 5700

Remark:
X1 = UcD180HG-HXR 模組 x2pcs
X2 = UcD Supply HG Mono 電源組件 x2pcs
X3 = Transformer 變壓器 x2pcs
X4 = 機箱 x1 pc
X5 = All accessories: RCA connector, Output Connector, cable, Switch, etc..
X6 = Training overhead cost

Data:
X1 = HK$ 2100x2 = HK$ 4200 (Ref: HiFifever website)
X2 = HK$ 1200x2 = HK$ 2400 (100 Euro /each, Ref: Hypex website 1 Euro = HK$12)

Subsitute the data into the equation, we have:

4200 + 2400 + X3 + X4 + X5 + X6 = 5700
=> 6600 + X3 + X4 + X5 + X6 = 5700

The equation is valid if only if X3, X4, X5, X6 are negative number. It is self-explained that the UcD180HG-HXR module will be purchased from Hypex, other components will be sourced from other.
I have listened the demo. The sound quality of this machine is good. Since I have personal business to resolve recently, otherwise, I have already made the deposit. Hence, my comment is that the price is reasonable.

B. regards,
alant

alant, thanks for the explaination.

We have the option to use UCD HG supply / HG supply mono, just to pay the product value and you can build that with your UCD.

It is a judgement between cost and patent technology. The Class D technology of UcD 180/400 HG-HXR is a patent module. Hence, requires to buy from Hypex although expensive. For other components such PSU, transformer, softstart unit, etc..., local customer-made components are good alternative if there is no significant difference in sound quality between local and Hypex material. In fact, both cases will be considered if I confirm to start. Thank you for information.

William san,

pls contact me at 8202-3367.

Thanks

William,

I would like to know if UCD 180HG HXR can use the think black colour case as we use in the pre-amp class?

By default we will use the DAC case for the UCD amp.

If you want to use the Full black case, just to add the difference of the case price (should be less than $100) but you need to open up all holes if you use the "full" black case without any pre-drilled holes.

William,

I will be out of town on 19 April. Is it possible to arrange another date or finish on 12 April ?

Raphael, we can have supplementary day to finish it after 19th Apr.

Hi William,

I have paid the deposit by Paypal for 180HGHXR. Also, I would like to use the black colour case.

Raphael, thx!

Very happy with my new 180 UCD amp.
Sound is excellent with lots of details.
Bass is not as that authoritative as expected from an 180-W amp.

A bit regreted for not upgrading the capacitors to Jensen in the power supply.

  

I am very interested about this! Please reserve a seat for me if there is a same course in future. Thank you very much!
