My, what sexy meters you have! This stack has got it all. The dual-mono 200 wpc monster amplifier was widely hailed as best-in-class when unveiled in 1987, and can handle just about anything you throw at it. This survivor passed our bench tests with flying colors, and went straight to the listening room. The P-308 preamp delivers superb quality with flexibility - 8 inputs including CD, Phono, 2 Aux inputs, and supports up to 3 tape decks at once (including DAT!). If you're able to pull your eyes away from the meters long enough, you'll notice exquisite details from the gold badge and subtle wood cabinetry, to the smooth controls. This stack looks as good as it sounds, and we're sure you'll fall in love.

- Liner Notes
- For the serious audiophile searching for musicality, transparency and control flexibility at an affordable cost, Onkyo presents the Grand Integra P-308 preamplifier and M-508 power amplifier. The M-508 delivers the promise of power and musicality, using the same design concepts first offered in our remarkable M-510 amplifier. Incorporating Onkyo's real phase technology, the dual mono 200 watt per channel M-508 impressively drives even the most complex speaker systems. The P-308 disprove the axiom that preamplifiers can offer either control flexibility or superb sound quality, but not both. The P-308 offers unmatched system control flexibility, together with technological refinements such as shielded power supplies, special signal path routing, and passive tone equalization with full bypass capability.
