Jolida JD301BRC review
How can you build a budget integrated amp that is a super-achiever in terms of sound quality? Jolida has found the formula. They know pre-amplification affects sound quality more and power amplification determines if the speaker is properly driven. They choose 12AX7 as pre-amp tubes, which are very popular because of low price and good sound. Power amplification is done by LM1875 OP amps specially designed for audio applications by National Semiconductor. Don’t be misled by the notion that IC is not good for hi-fi, because there are super-fi amps (47 Labs) using this exact IC. ICs perform well because they are designed by real circuit experts, and are cheap due to mass production with advanced technologies. Furthermore, circuit design becomes straightforward because standard diagrams are available from the manufacturer. Ever wonder why a computer with countless transistors is much cheaper than a hi-end amp with so few? Hi-end is not cheap mainly because of in-house design and small-scale production. Jolida figured out how to make two cost-effective, well-proven components work in synergy (no exotic design) and manufacture them in China. How can you get a value/price ratio higher than that?
