What kind of amplifier is the Hitachi ha-6800?

The Hitachi HA-6800 is a very clean and transparent sounding amplifier. It is designed using a single pair of classical Hitachi lateral MOSFET power transistors per channel. The schematic shows the most advanced of the Hitachi amplifier designs, with an extra emitter follower stage before the second differential amplifying stage,…

What kind of amplifier is Hitachi hma-8500 Mk II?

The Hitachi HMA-8500 Mk II is a high quality 100 watts-per-channel MOSFET class AB stereo power amplifier. MOSFETs are solid-state devices that work on principals more similar to vacuum tubes than bipolar transistors — and it sounds great!

What kind of stereo amplifier does Accuphase have?

The Accuphase P-800 is a Balanced Stereo PowerAmplifier. Completely balanced powerful output stage consisting of two sets of 7 parallel push-pull transistor pairs, outstanding low-impedance drive capability, separate power supplies for left and right channels, balanced input.

Which is the biggest stereo amplifier in the world?

Original sale price was 30.000 DM in Germany. Introduced in 1984 the Grand Integra M510 was the biggest stereo amplifier built for home use by ONKYO. The M-510 has completely separate L/R channels all the way back to the power switch and AC cord.

What are the specs of a Hitachi Ha-6?

The HA-6 is also known as the Lo-D model HA-505 in Japan. It has an exceptionally good MC/MM phono stage, with a quoted spec of +/- 0.2dB RIAA deviation from 20Hz-20kHz and low noise floor. The output stage is cooled with freon gas in a heat loop. All in all a very nice offering from the 1980s.

When was the Hitachi ha-7700 power amplifier made?

Claimed to be a synthesis of the previous HCA-7500 preamp and HMA-7500 power amp, the HA-7700 condensed the best parts of both designs into a single, elegantly styled (if still substantial) chassis. The HA-7700 is detailed in the 1980 Hitachi catalogue.
