It has been quite a while since I got it. It definitely wasn’t expensive. I gave it to the electrician who pulled 2 dedicated power lines (living room hifi and room hifi) to install.

How much is this hifi grade power socket?


I have a similar one which i bought in 2014 from ISSE for my main system. Less than $150 iirc.
When I moved house I bought 2 sets of Oyaide R1 for my main system and shifted the Sine for my HT setup.

Guys, just wondering if 20A per line is enough.
I read my amp's manual (Bryston 4BSST2), and it says at max power driving a 4 Ohm load, power consumption is 15A. Will I ever hit that during normal usage situation, given I play mainly vocals, jazz and no classical music or loud rock?
What if I add another 4B SST2 and bridge them to become mono?
Lastly, what disadvantages are there if it is a 30A or 40A line (dunno if that is even feasible/allowed, lol)?

u gonna install US or UK wall socket?

Also, since u are using power amp, please inform the electrician to install type C MCB instead of the standard type B.  Else u might find the MCB tripping when u turn on your amp.

15A for amplifier,

Bro, I went to look up 4BSST2, max is 2.1kW.
At 240V, it’s about 9A.




My guess is most folks listen in the 90-100dB loudness range. Assuming a low sensitivity speaker of 86dB/W, that means the amplifier would be running in the 3W-30W per channel range only.

Factoring inefficiencies, lets say 200W constant average power draw for stereo, thats less than 1A. With 9A peak draw, I think 20A cable is more than enuf.

The Bryston can pump 15 Amp into your 4 ohms speaker.  That is only 900W.  This is because there is a step down transformer in your amp which lower the voltage but increase the current capacity.

A 20 Amp line could theoretically provide 220VAC RMS X 20 Amp which gives approximately 4.4KW.

Plus all electronic devices sold in SG will not require more than 13A, else cannot fit a 13A UK plug. Only certain devices like aircon, heater, oven will need upto 20A.

Get one of these Watt meter to be sure
My guess the amp will draw less than 300W (less than 2A) during normal playing.

Dont need to waste money on using audiophile power cable from MCB to your wall, afterall, every audiophile cable will have a character and it will make you hard to tune your sound later when you still need to distribute with another highend audiophile power cord. Stick with standard wires but ask the electrician to run 4sq mm at least and if you can convince him to run 6sq mm, it will be even better.

Ask the electrician to make you another set of ELCB and MCB parallels to your incoming power line to the house with the whole house circuit breaker. If possible, use some audiophile elcb and MCB, they make huge difference. Finally terminated your point with some high quality wall socket like Wattgate, Furutech (do your research as each socket have their character). they come with Gold, Silver, iridium and each have their own tone and you cannot have one stroke for everything.

PM me if you need more detail and consultation. Dont worry, it is free of charge for consultation. Just that i dont want to put all detail here to accidentally offend anyone.

ordered one reel 95m of this 6mm2 shielded OFC wire , Arrive 1 month later $5 per meter, MOQ 6 meters $30, I will use about 45 meters, left over will sell away.

self collect at Pasir Ris , those who interested to use this as in their Dedicated  power line can PM me

Used 2 runs of Belden 19364.

Because of the long run through the ceiling with LED transformers, noise rejection and draining of the wiring is considered, just to be safe.
