Arcam SA30 with Lulon and Jamicon Capacitors - Chuyên Trang Chia Sẻ Kiến Thức Thời Trang Mới Nhất

Hi Felix, thanks for the response.

I have spent more than 20 years repairing, modifying audio equipment and I can confirm the Caps are a huge part in the sound quality and reliabilty.

My concern with this case is if you check the inside pictures of the SA30 in the majority of the reviewers pages you will find the BIG NICHICON Caps in the power supply , not the Lelon and Jamicon. That influenced a lot in my decision to buy this AMP. My suspect seeing the evidence is that they maybe send prototypes or devices as you want to call it with better parts and of course will sound better. These is not a conspiracy theory, is a Fact and the evidence is online.
Audio need the lowest ESR possible in caps, best values of leakage current and low Tangent of loss angle (tan δ). If we investigate about the caps used in the SA30, at least the batch I got they used third and fourth Tier Caps, that means low cost production and I see them fail a lot!

PSUs 101: A Detailed Look Into Power Supplies

The objective of this article is to provide detailed information about the most crucial part of a personal computer (PC) system, its power supply unit. Follow us on this journey into PSU territory and we promise that you will gain valuable knowledge.

If you check all the ARCAM DVD series , CD series from the PAST, there is no one Chinese Caps. You will find Nichicon, Rubycon, ELNA, United Chemical etc. They last forever and they were not tagged as HIGH END equipment. If you open any ARCAM from the gold ERA, or Sony you won’t find these Chinese caps.
My point here is that for the price point of the SA30 I think better part must be used, in the price range of the SA30 there is a lot to check and compare. As I mentioned above, the pics with the NICHICON CAPS in the Power Supply influenced a lot in my decision to buy this amp, of course the features were a plus to. But knowing the quality of parts used maybe I could not buy it. Class A, AB, D, G etc need the better power supply possible, the better parts possible to sound as is best, there is not doubt on this.
