usually what kind of wire you guys use in the amp for signal path?
PCB to RCA in/out and speaker in/out?

solid core but vary AWG.

how about Canare L2T2S or solid core is better for RCA?
I see there are a lot of comparison and review around the net but without a good conclusion. They said Canare is 1 of the best interconnect while solid core is the best too as it has lower capacitance.

for speaker input/output also use thicker solid core AWG?

any good performance to price ratio solid core to recommend?
like pure copper or...

use OCC based wire lah.. hmm if copper then PCOCC if not then OCC.
OCC is still better than OFC.

Different people different taste, I like fine stranded copper cable more than solid core, it is more flexible to install. IMHO that short distance inside amp wouldn't affect that much unless you have a golden ear, there are some expansive CDP used computer ribbon cable in signal path. You go figure is it worth the money or not.

If you want cheap solid cable, can try CAT5. If you want thicker can combine a few together. Great sounding cheap cable. Only thing I don't like is: very inflexible and the sleeving easily tone and puncher by heat.

As for me, I will change the internal signal wiring (RCA@SPEAKER) after the system have been tested for sound. The wiring for internal is quite critical but mostly I choose a thin solid core wire (copper or silver) because my designed amplifier is slightly sound smooth. The internal amplifier speaker wiring, I regularly goes for ticker one (High grade Copper) and make shortest possible to the terminal. Sometimes I choose a very thick single solid core for it (or multiple solid core). Try to experiment with difference type of wire. Yes it still get some good result. The wiring for RCA path must be aware from the power section unit, in my experience in building and design amp, the sound that RCA path near to power supply (AC or Transformer part) will get blur sound. But I did not go for further analysis on this. But most of all is depend on your own taste. This suggestion is from my own taste.

stranded is somewhat better than solid core in technical aspects.

For instance, skin effect, where the frequencies only travel on the surface of the conductor. Stranded somewhat increases the surface area of conduction.

I use solid core all the time for internal wiring for electronics. Much better and cleaner work. It's really just your preference.

Do not however, use solid cores for high power cables or long external cables because they don't bend flexibly.


Protip: Mechanical considerations.

@vir___killer: where can I get the OCC and PCOCC cable locally?

@kww: stranded really easier for installation. I broke solid core cable before, just slightly bend it only.

@nanhifi: I also plan to replace the crossover pcb with wiring only.

@LittleGhost: currently I'm using Mitti High Resolution Silver Coated Copper cable but don't know how is the quality of material. RM5/meter only.

where to get the silver coated copper cable? can PM me? thanks

It is tinned la for that price. Silver coated easily 20x more.

oh. then the boss cheated me, simply told me it is silver.
nevermind lar, rm5 only.

vir_killer- Placing the pcb crossover traces with cable. I have not do that, and does not know the result iether. Have a try maybe you will learn and get something. I only change internal wiring for the loudspeaker and it does effect the sound stage.

oh ok.. i knew that.. but i not my current speaker lah.. i am not gonna invest on my old speaker. perhaps new 1.

quoted from " http://www.clearcables.com/about.php "

L-4E6S uses four 24 gauge annealed copper conductors, that when combined and soldered into the Canare F-09 RCA connectors, result in a pair of 21 Gauge balanced conductors. We ground the 95% braided copper shield to the "transmitting" end of the cable, for superior noise rejection. Other manufacturers mistakenly ground the shield to both connectors, resulting in two ground paths for the cable, and therefore a "ground loop" which causes noise. Excellent frequency response is maintained due to the use of a special irradiated polyethylene insulation which provides a low capacitance dielectric.

I'd appreciate it if you guys can explain the bolded part

pakai speaker apa?

changing wiring not necessarily improving it. Character might change....but depends to you liking.... The simplest might be P2P wiring with new sets of caps.....

AE eagis One (Murah je beli masa study dulu). There are many debate on how wire will change the sound. But after a long time of experimenting on this, I finally stick on what I have change it. My speaker now have a better soundstage and layer it well then original. But it also limit cause by the driver, crossover part, crossover design, heat diavation, amplifier, source,room acoustic and etc. So much to be fine tune and tuning process will never be end.. So far from my taste yet. Keep on doing so and it will show you that there are so much to be learned and new finding you get...

kalau nak mod speaker banyak yang kene buat.....paling kritikal masa nak tune...banyak sangat parameter nak kene consider...paling senang ko tukar kapasitor aje lah...same value but different quality. Kalau pandai-pandai tukar value nanti frequency response dah lari. Kalau pandai-pandai sangat solder & desolder sebab nak eksperimen diferent type of caps nanti pcb pulak rosak.......tepuk dada tanya selera....

senang lagi kalau mod amp atau digital devices....IMHO

Aku teringin sangat nak dengar ko punya Bee amp sebab aku dah follow ko punya development sejak bertahun-tahun lagi....bila nak ajak rumah nie???

bro nanhifi, kita gi raya rumah bro leh?

Here is my latest headache..........aihhh!





Not sure when I can finish this amp.........

seriously welcome any idea or comment!
