   During the 1970s, the MC-2300 was an expensive piece of audio equipment, with a retail price of $1799 by the time of its discontinuation in 1980. [1] That being said, its outstanding power and sound production quality made it a valued part of many recording studios and although some people prefer the sound of tube amplifiers, the overall greater reliability and freedom from repair of the newer ...

3. Impedance matching - Wikipedia

   en.wikipedia.org/wiki/Impedance_matching

   Typical push–pull audio tube power amplifier, matched to loudspeaker with an impedance-matching transformer. Audio amplifiers typically do not match impedances, but provide an output impedance that is lower than the load impedance (such as < 0.1 ohm in typical semiconductor amplifiers), for improved speaker damping.

4. Instrumentation amplifier - Wikipedia

   en.wikipedia.org/wiki/Instrumentation_amplifier

   Instrumentation amplifiers are used where great accuracy and stability of the circuit both short- and long-term are required. Although the instrumentation amplifier is usually shown schematically identical to a standard operational amplifier (op-amp), the electronic instrumentation amplifier is almost always internally composed of 3 op-amps ...
