Stereo Integrated Amplifier (1980-81)
The NA-1090 gives many of the same features of the more expensive NA-2090, and is a superlative value by any standards.
DC configuration power amp delivers consistently high damping, uniform phase response in mid-to-high frequencies, and virtual absence of TTM (Transient Intermodulation distortion).
The sonic difference is distinctive: crispness and clear stereo imaging from super lows to super highs.
Built-in pre-preamp for moving coil cartridges can be switched from a front panel control.
A record out selector even lets you record whatever program to which you're not listening - you can record a radio broadcast while listening to a record, for instance.
Five LEDs for each channel indicate the level of the moment-by-moment power delivery with electronic accuracy. The NA-1090 connects two tape decks.
