THE ORRONOCO AUDIO DIY

I have been working at home since last Thursday, this is because of the corona virus pandemic that spread already. Stay safe everyone, stay at home. Actually it is quite boring if not do something related to my hobby. So in this opportunity I pull out my old Technics amplifier from the cave. This amplifier is built around 1991, the model is SU-VX500. It is still made in Japan and the great things about this amplifier is the Class-AA patent technology that quite make this amplifier famous at that time. So let see the inside and I will do a lot of cleaning to make this amplifier like new again.

If you wondering where is the part 1 of this post, then you may check in the link  here . When we are talking about capacitor for car audio, one thing in mind is the big capacitor that mostly put at the trunk of the car, near the sub-woofer and the power amplifier. This capacitor is flashy and eye catching with digital volt indicator on it and few LED. But that's how it works for the sound pressure level improvement on their car audio power supply. That capacitor stored energy and release for instant demand need by the power amplifier and the sub-woofer. But right now, I am not talking about that kind capacitor function. Just put away those capacitor first. I will focusing the capacitor for the car head unit. This capacitor must be good in specification, high quality rather than only high storage (Farad) capacity. This capacitor function is mostly to improve the power supply ripple rejection cause by the car alternator. The voltage go to the head unit will be much  cleaner. ...

I got a request from one family member to install an audio-video entertainment in car. Hmn.. not a good idea for myself since I already satisfy with my current audio system here   here  and here . But I think I will do it. At least I should experience myself for having an AV head unit on car. It will also become a new review here too. So I did searching the suitable AV head unit to my car within my very low budget and end up to this Pioneer AVH-G115DVD. This head unit is very cheap, but don't compare to Chinese brand head unit, they are different class for sure. I got it for about US$100 brand new and this is what you should know about this cheap head unit which I believe no one will telling you about this.

The Sennheiser HD600 is an old product, you probably couldn't find the new one these days. As per information going around, this headphones is first release on 1997 and I am not sure why it is gone in the market right now. This HD600 is fortunately still can be obtain but in the second hand condition. The HD600 sound quality is the best said many reviewer. But is it? I have been using for a while the Massdrop Sennheiser HD6xx and I am really like it. You can find my review about the Sennheiser HD6xx in this  post . Then how about the improvement this HD600 over the HD6xx? So I guess comparing the together will get the clear picture which one is the best.

My review yesterday about the sound quality of this SMSL SP200 headphones amplifier surprisingly got a really good result. This is the most affordable THX certificate headphones amplifier on the market right now. Comparing to others manufacture, I saw they also made similar amplifier with also THX certificate and the main components inside is also the same. But the selling price is way more higher than this SMSL SP200. SMSL official websites have published the picture about what components they are using inside it. But I guess, if you're me that so curious to see it directly, you will do the same as I do, digging deeper about components inside it and finding any potential components to upgrade.

SMSL is an audio manufacture based on Shenzhen, China. This company has been around for many years selling high quality audio devices mainly for desktop audiophile system. The most appealing product from SMSL is of course the very affordable price with decent build quality and uncompromising sound quality. The SP200 is their current desktop headphones amplifier announced about few month ago. Still new and fresh since this is their first product to get the certification from THX. Not sure what it means, but it appeal to become great for music. So let's find it out.
