R&D in process!

It's time where our sound systems reach another new height of SQ(Sound quality)... I remember back in year one, we talked about boomyness, and loud music with lots of midrange in the music that produce vocals. Therefore, unknowingly, we think it's good music. Having played the Burmester CD (Audiophile test disc) that time and now, yield completely different results. The sounds we are getting now is mind blowing!! The music can reach a level so real, he though I was talking to him! Yes! Vic! It's all his fault. Went to Koba(a place selling electronic parts) and saw some high grade capacitors for a relatively cheap price and decided to give it a try. FYI, capacitors are charged storage devices that can be music cross-overs(a electronic component that determine which frequency range to drive individual speakers), differen capacitors produced different sound signatures and will give different amount of sound detailed when used.

The 2 types midbass electrolytic caps I got, Elna Silmics and Rubycon. The Silmics has been highly rated due to it's fine construction and muscality. You can do a search on google on silmics and they will thrash you loads of info about this fine capacitor.
Lousy electrolytic capacitors that was originally installed

Elna Silmics on board!

Next part, will be the myths on bypassing capacitors. It was said online and by many people. If a capacitor is bypassed by another of a smaller value, it's able to extend higher treble to recreate an instrument sound better. Intially, I bypass the Silmics with Cheap wima 0.01uFs from koba. and the tweeter capacitor, Solens, with wimas 0.001uF.

Cute transparent Wimas bypassing the Solens

Wimas 1nF capacitor! Cute rite!

The day after, Vic went to get Mundorf supreme capacitors, they are huge grenades and is suppose to replaces the black solens u see above. Best of all, they cost 40 dollars each! In a stereo sound system, thats 80 dollars for just capacitors. He has his doubts. I have mine, it's just amazing this famous and highly recommmended capacitor can really make a difference in ANY sound system. Here is how they look like.

Look the yellow capacitors on the left, the flat pack one is a size of a man's thumb. Can you imagine how big are these babies?





Now, compare it's shear size of it with the other of the components.


And of course! it sounded better than my crossover set I have. We tried playing cai qing, the cricket track. It sounded less rounded and full body on my set compared to his. With his, I can hear the low rough ruffles of her deep voice and shes like singing live infront of you. I am pretty impressed with it but do not have funds to purchase it yet.
:( Mundorf rocks!

However, the modification process doesn't stop here! Vic went to buy some vishays 0.01uF tolerance of 1% capacitor for both of us. I removed the wima bypass and filled in with this, and he bypassed his mundorf. Bother of our cross overs are burning in now. With hours of listening to it, we are quite happy with the results! It's a big difference the sound system now compared to 2 years ago! How NOOBS we are =P

ANyway! some interesting pictures to show "off". I made crepes, it's very nice and sweet! My mum made the batter, but i made it! It's much tastier than a pancake and goes with with tea! Very nice for an afternoon snack...









Also, I got pretty donuts from donut factory suntec, just 30 mins of queueing. Damn fast. Those people who has more timee and are sooo free, queue @ raffles please!

One nice place I went today is Muchy donuts @ katong. It taste different all together. I cannot say which is nicer. But i like the oreo flavour of muchy donut!!! :)




Also, went to fei fei won ton me, the new outlet and found bad english. Can you spot it? =P

heh!!








What's recommanded?

:P

Schools reopening. I like! Missing all those studying period! Call me sick but i hate doing nothing!
For now take care peeps! Enjoy the hols!

Extra Curricular Activities

Has been rather lazy to log on blogger and write something. Well, just 2 sundays ago, WJ, JR and I went of a trip up to the casinos. A place where grandma love to hangout. SOmetimes u can see grand dad placing their life earnings in that place of hopes and dreams. To kids, that place is just a theme park, to us adults, it's more than that~... Poor people play TAI SAI OR ROULETTE, however the rich people will be able to play card games like carribean stud, etc...

Temperature constantly at 20 deg celscius, it's just like constant air condition, with occasional sputter and gust of wind to provide the extra wind chill shoikness. I love the cold and I have been sleeping in the aircon room since 4 years old. I NEED IT! 113 sgd for full package with buffet breakfast. it's so cheap I feel like going back every weekend, not for the casino, but the weather =)

We went on an off peak package, constituting sunday monday and a tuesday. Having reach that on a sunday afternoon on a super duper slow coach, about 6-7 hrs of journey, we decided to take it slow and go for the theme park the next day.

Monday morning, themepark day. The breakfast isn't all that impressive, what i like best is only the laksa chilli, which gives me spicy tingling sensation with spike of aroma bursting out of the ikan billis... BaGUS!

the day was so cloudy we didn't actually do the out door theme park. Worse still, many of the nice rides were down. Therefore we bought a 21 rm indoor theme park ticket and played our asses off at the bumper cars. In total we queued for the bumper cars 6 times, 3 mins / play and it was great fun! We had our enemies, little uncourteous rascals in the queue we identified, and we bump them~...

Moments before our 1st ride @ the bumper cars, we took the indoor "roller coaster". A minutes ride took us about 15 mins to queue. JR and I wanted to take front seat and we waited for the next coaster to come. Just when we were about to board the coaster, this middle eastern toddler ran from the rear of the queue line and jump into the front seat. Only then we felt owned by the kid. We can't possibly tell the kid to move to the rear. Blame it on our complacency. :(

That most of the excitement in Genting.

Today, Vic was free! so nice of him to offer his help to install another amp in the car. I was in dire need of a dedicated amp for the sub woofer. Although I had the amp with me for almost 6 months, I don't know how to remove those hindering car seats. Vic, with his professional experience with zhnging car and this big collection of proper tools made everything easy. I was just amazed on how car seats can be taken out so easily!!

Especially the rear seat, no screws, just brute force, pulling the entire seat from the clips.
We even found 1dollar ten cents in the rear seat. I am sure thats from one of my passenger. Thanks for the TIPS =)
The amp i threw in is a 300 watter, My diamond D6 sub is able to tahan 600Watts.
The last time, running from just a single amp. I threw in only 182 Watts, that barely 1/3 of the rated power of the sub.
Even now it's just 1/2 of it!
With this relieve off my old amplifier, the fronts are getting 3X more juice and the rear 2X more juice. And the music is turning more lively now!
With a little more tuning, I am sure ill like the sound so much ill just live in the car next time.
Feel free to approach me for auditions! I AM SO HAPPY WITH THE SOUND NOW!

Anyway, installing the amp 1/2 day of work for 2 people.
Here are some pictures from the Genting trip and today!

Once again thanks vic for helping me!! You are so nice =)


300 Watter lying @ home
Talking to terry yesterday, he told me to take out my old DSLR camera to snap.
Pictures today are of fascinating quality, it's from my old canon 300D, trying out nice snaps.
Now my ICE setup,
1X Alpine 9855
1X REVO DAB
1X ADS 236 IM components BI-WIRE (Modified Solen capacitors passive crossovers)
1X stock Toyota speakers made by fujitsu ten
1X Diamond D6 Amp 2 ohms series DVC (4 ohmage configuration)
1X Diamond 3400.4 Amp running on 2 channel (182 watts/ channel @ 13.8 V)
1X Schneider Amp running on 1 channel (300 watts)
Planning to buy a new 600 wattage amp for the sub, and improving the components speakers.
Brands in mind
- DB Drive
- Focal
- Danish Acoustics
- Hope to try Home audio quality paper cone speakers (Scanspeak, Focal)
Now i need is just some nice CD's and songs!
Enjoy the music peeps =)
