low distortion audiophile composite amplifier kits based on LM1875 tda7293;
Building an audiophile amplifier with ultra low distortions and superb sound is really easy with Low Distortion Audiophile Amplifier Kits LM1875 TDA7293 and it won’t brake your bank account. You can choose different kits in accord to your personal needs. The main building blocks are: Ultra Low Distortion Kit based on LM1875 and Ultra Low Distortion Kit based on TDA7293 / TDA7294.
By combining 2, 3, or 4 blocks from one of the two kits you can achieve output power up to 250W with extremely low distortions.
ABOUT This website
There are many myths and idiosyncratic ideas about the good sound and how to achieve it. After many years of experimenting and building I’m happy to share with and help those who are interested in the subject.
In particular, I focus on the composite audio amplifiers based on IC chips LM1875, TDA7293, TDA7294. These IC chips are very cheap and composite amplifiers based on them sound extraordinarily well. These two combined together make the subject pretty interesting, I believe.
For those unfamiliar with the subject I have to say that the composite audio amplifiers are made by inserting a monolith IC power amplifier in the feedback loop of an operational amplifier. The resulting ”turbocharged” composites retain the low distortion, noise and offset of the operational amplifier and the high-current handling capability of the power amplifier. Ultra low distortion and noise achieved in this way determines the extraordinary sound of a composite amplifier.
