The All Indonesian DIY Collaboration

This time I will give my personal experience of DIY Collaboration between VD SIGNATURES, AMBITUS drivers and ANDA Amplifier.

The drivers came to me from a friend named David Karjadi which is the person who held The Indonesian Brand of Ambitus.


The specification quite good so I decided to make a DIY Loudspeaker together with Mr Fidy Purwoko of VD Signature. We have made some open baffle for midrange and tweeter in pyramid shape enclosure and for the  bass we decided to put the woofer in dual port bass reflex enclosure that tuned in 35Hz 




We made several test with various audiences the amplifier which being supported by  ANDA Amplifier (Blameless 2x100 and 2x150 watts per channel). ANDA in my opinion are clear, clean and powerful power amplifier with lots of headroom. The amplifier were made by Anistardi Sudikan and Daniel Suroyo (hence the name ANDA) and 100 percent made in Indonesia


We also use CD Player and Hires Source Player for the test using Sepanjang Jalan Kenangan CD from Sangaji recording and Lucky Sing Broery from Platinum recording. We also try Three Blind Mice Recording of Tatsuyoshi Yamashita Misty for the hires recording.

The combination of the system gave us solid staging and imaging and the proportional tonal balance and tonal accuracy. Almost every music we put on them could reproduce it beautifully with decent separation, spacious, but also neutral and musical. We were happy for the result of all Indonesian Audio Gears...

Best Regards

In my humble opinion hires is the ideal format to listen to the music. The versatility, high quality and ability to play them in car audio or home audio make the format getting more and more popular in music lover. Also thank to the large memory card or usb, as reliable storage for Hires format.

Sony as one of most company which is really serious into hires format in 2015 released their first head unit named Sony RSX G9. Now after a year waiting for my unit. Finally I can have it on my personal sound labs.

The Hires Album

1. Three Blind Mice - Tatsuyoshi Yamashita Misty 24 Bit PCM 192Khz
    This Japanese recording is one of the best in term of dynamic and ambience.

2. Beethoven Monlight Sonata DSD 1 Bit 5.6 Mhz
    An example how the good music on the good recording can make goosebumps!

3. Lucky Sing Broery WAV 16 Bit 44.1 Khz
    Indonesian singer that really has great voice and great interpretation of the music

I must tell you that in order to play the music properly you must make folder named music and put all the Hires files into it.

The Review
1. Misty feels like...ah that song with clean and detailed presentation, very dynamic and palpable imaging.
2. The Moonlight Sonata track is one of the best classical composition from Beethoven to make our soul energizing. On the Hires format this song is closer to perfection.
3. Warm and tender sound of Lucky make me want to listen to his voice more and more. Liquid, sweet and soulful. What a sound!

The Result

Pro:
1. Clean and detailed sound
2. Somehow the high is very extended 
3. Smooth tonal balance and great imaging

Cons:
1. Relatively high price tag (but worth the money)
2. Can not play DSD higher than 5.6 Mhz sampling

Now I can enjoy listening to the Hires music in my car. I'm so happy to have this as part of my audio gears. Thumbs up to Sony!
