CSE stepdown transformer ?

[Raymond Wan]

I have 3 nos. old version CSE Regulator / Transformer.

However, the E-series does not have step down function while the TX-series do have step down function.

(1) CSE E-500 Isolation Regulator




(2) CSE TX-1000 Isolation Balanceformer with Stepdown to 117V and 4% Correction (i.e. ~121V for N. American Equipment)




(3) CSE TX-2500 Isolation Balanceformer with Stepdown to 100V and 4% Correction (i.e. ~104V for Japanese Equipment)

Very detailed pictures. Thanks Raymond

Cam hing, you are welcome.

Please note old version TX-series will have step down function.

Besides, the step down voltage can either be 100V or 117V, both with 4% correction to adjust the potential lower input voltage of 220V.

However, for latest CSE models such as TW-series. They do not have the step down functions.

If you need it, you need to place a special order to CSE for extra cost.

You can call up the HK Distributor - Audio Extreme for the details.

How's difference in performance between regulator one, and transformer only one?

CSE E-Series, RK-Series or RX-Series are Isolation Regulator 電源處理器

http://www.audioextreme.hk/new/cseRegulator_chi1.php

CSE電源處理器是將市電以AC轉換成DC後再轉換回AC之完全組合型式處理, 即是將整個交流電弦波重組, 供電原理有如一仲但甲類後級放大器。
因此,CSE電源處理器除能過濾電源外,亦帶有完全隱壓之功能。較高型號更有不同數值之交流頻率調較以改善音色上之表現。
電源處理器製作成本和體積相對隔離牛會較昂貴和巨大。
聲音取向會以高頻幼細,分析力高為主,適合音源及前置等之精密機種使用。

CSE TX-Series, TW-Series or T-Series are Isolation Balanceformer 隔離牛

相反,CSE之隔離牛是以一種特別製作之W.B.Tram變壓器作為交流電上之過濾模式。
但因為是變壓器關係,故能給予不同標準電壓輪出要求,而且更有平衡電相供電和備有升壓功能。
音色表現以大動態為主,所以適合耗電量較大之器材使用。

I use E-500 for HiFi Source and Signal Handling Equipment such as Mark Levinson No.31.5 CDT and No.380S Preamp.

I use TX-1000 for AV Power Amp Related Stuff such as M&K MPS 2510P Active Powered Front Monitor Speakers.

I use TX-2500 for all other AV Gears such as:
(220V) Lexicon MC-12B, Marantz DV9500, HTPC, Mitsubishi HC2000, Parasound A23
(100V) Victor HM-DHX2, Yamaha AX-2500

I tried to compare the performance of E-500 (Regulator) and TX-1000 (Balanceformer).

Although TX-1000 is already quite good, I consider E-500 is even better.

Using E-500 for the HiFi Signal Equipment can provide you very quiet background and hence more details as well.



However, the cost of a E-500 (500W) is double the price of a TX-1000 (1000W).
Similarly, TX-2500 (2500W) is bigger and heavier than TX-1000 (1000W) as well as the cost of TX-2500 is twice of TX-1000.


Hence, CSE Regulator is trying to make good the AC Sine Wave so as to provide perfect noise free current.

Incoming Current --> Regulated Current

While CSE Balanceformer is just to filter the incoming noise without the function to improve the AC Sine Wave.

Hence CSE Regulator is a Power Plant while Balanceformer is a Active Filter.

In fact, CSE Balanceformer is better than most of the Passive Filters available in the market.

Oh, I see. Very detail explanation.

What would you recommend for average Hifi gears of around HK$40,000 to HK$50,000 (CD, DAC, Int' amp)? Choose regulator or isolation transformer. Don't tell me both.

As I mentioned above, the Regulator is very effective for CDP & DAC & Preamp (low power demand).

Therefore, you may consider an entry product, a low power output regulator such as RK-100 (100W) at around HK$7.xK for CDP & DAC.

If you have a more demanding (i.e. higher power) equipment, then you may consider to get a TW-1000 (~HK$1xK) for all your HiFi gears.

However, for Integrated Amp, I do not recommend to use the Balanceformer unless you use very high power output one such as with at least >2000W.

Using lower power output Balanceformer will limit the current and will have negative effect on power performance.



In conclusion, you may just get a RK-100 initially to appreciate the immediate improvement of your HiFi source.

Later, if you find you need to do more on current treatment, then you can consider other equipment.

Hence, invest an amount of HK$7.xK or less (for a second hand) RK-100 is worthwhile to be considered.
