Could be the plug or the female jack problem? Coz I faced some cases that didn't fully contact can happen to be no bass instead of no sound at all.
Mind to check it out?

Have you try out with other earphone or headphone on your HCS2330 amp?

Added on October 20, 2011, 11:53 pmIf you can put your budget to C3, go for it. There are quite a gap between M3300 and C3 in performance.
Not to worry if you're not into strong bass, there is bass volume control in C3 or M3300.

I prefer S530D because of wooden enclosure and class AB amplifier sound smooth and relax to my ear.
T3 uses class D amplifier, it sound harsh to me.

T3 lack of bass?

It already shake my pants liao....

S730 is for ppl who needs more bass from S530 that is how it came out....

Overall performer S530, need more bass and louder volume from S530 = S730.

He is a good cable maker, you can try his cables with reasonable price and great performance.
By the way it has different feel than you changing to a good speaker set.

Remember that try to position as precision as possible with measurement tools, it really affects a lot on your listening experience.

Consider relocate the main switch to a convenient place?

Mind to try widen the space between both satellites to create some wide space effect?

Wah I didn't know that...

Anyway, speaker position is really critical as I found Edifier speakers are quite sensitive to position changes. Suggest using ruler to mark the position and then you'll get excellent stereo image like vocal comes out from your monitor.

Depends on the speaker design, some not sensitive some sensitive.
So need to test out yourself, manual no write about it

Just to share you all how I position my speaker using 15cm ruler, using table and monitor as reference.
What requires are the length a = d, b = c, e = f.

M1360, coz it has good performance under such a budget.
You can go for X220 if volume control stuck at the back is not a problem to you.

Better you go audit it before made your final decision.

Ops...I should say it is on the woofer lol

1. Get a sound card, internal or external also can.
2. Replace interconnect and speaker cables, replace yourself with network cable(Cat5e) will do great performance or you can get from ssyycc or some other people.
3. Mains power filter, prefer Belkin Mastercube because easier to find or try out something like TACIMA CS929.

All upgrade depends on how much you can put on.


chchyong89 wolfson wm8501 is a good dac, you can try it out.

Of course Xonar D2X

That can be your dumbbell..

DC to AC you need a frequency generator to generate 50hz frequency and step it up with a transformer. You can refer to switch mode power supply.


M3300 requires dual power supply like most amplifier design, which means +12 0 -12. You need to check the amplifier is single supply or not before you can hook it up directly with battery supply. If I didn't not remember wrongly, old Altec Lansing speaker is using 12V single supply, I did hook it up with RC car 9.6V battery pack before and it works nicely.

It is an illustration of how it works, not the real circuit yet. The real one will be a lot complex even me also donno lol.
Switching power supplies are efficient than the other type, but also depends on the design too because there are many factors degrade the efficiencies.

You can refer to car audio amplifier power supply design for better understanding.

12V transformer, and transformer always AC one isn't it? The rectifier circuit is the one that converts it to DC voltage and capacitor is use to smooth out the ripples.
