THE ORRONOCO AUDIO DIY

It is been awhile that I am using the Gainclone car amplifier  here  and the result is suprisingly good. My previous post  here  about the US Amps, makes me wonder how is the sound signature from the American amplifier compare to the the DIY Gainclone. For the music, I prefer dynamic sound with nice presentation on mid-range. Lets read on what my finding with this US Amps.

Most famous car amplifier in 90's era them are all made in USA. Just like Rockford, Orion, Linear Power, MTX, Petras and so many more. They are the American style car audio amplifier that feature true RMS power output. The sound is clean and loud. Today I got this US Amps in the mint condition. The model is USA-100 and I believe it is only 2 x 50 watt. Although at this moment I don't need any amplifier anymore, but by looking this amplifier condition, I could not resist to have another one.

I have a long holiday last week and I invited my friend to install the Soundstream Monoblock amplifier to his new car. It is a Suzuki Swift 2015. You can read my preview for the Soundstream amplifier  here . My friend is a bass lover. He love to hear electronic music, hip-hop, R&B, pop and worship songs. (worship songs in the middle of that said genres?) He is not to much concerning about sound quality, his goal is having an audio system that deliver deep, tight and powerful bass.

I am counting on how many years that I am not touching any bass oriented in car audio anymore. I guess it should be around 7 years ago that I selling all of them and then more focus to the sound quality. But today is different, I am looking for a mono-block amplifier that usually designed for driving a sub-woofer or more. It is requested by my friend. He ask me to find a powerful mono-block amplifier to drive his his 12 inch sub-woofer and will install to his new car.

Lately it is quite rare for me have a spare time during weekends. I mostly spend it with my family. But today is a different story. A week before, one of my friends ask my suggestion to install a 3 way system on his new Honda Jazz. Instead of a 3 way system, I suggested him to look at a small full-range speakers that will be place on top of the dash-board. This could help for minimizing blind spot while driving compares to the 3 way speakers system.

I have a 10 years old Seiko 5 watch which I like it very much. It is very durable watch I've ever wear. I don't even think to buy the new one until one day, I am unexpectedly jump into online forum that discuss about the Seiko watches. I'm really got into it and it is a very good affordable watch that I cannot resist to have one.

I think this post is quite special. In the past I built discrete Mosfet amplifier that very famous in our local DIY audio group. This is Mini Crescendo amplifier is from Elektor magazine featured circa 1989 and I built that amplifier in early 2000. Why this amplifier is so popular? Simply because it sound wonderful. This Mini Crescendo amplifier is class AB using expensive Mosfet 2SK135 and 2SJ50 together with big transformer. Unlike Gainclone amplifier, this amplifier is simple and cheap to build because basically it is an IC based amplifier. So I think this is really interesting to find out which one sound better. The expensive and complicated Mini Crescendo or simple and cheap Gainclone amplifier.
