Pass Labs INT-250 Integrated Amplifier
Like the INT-60, the INT-250 utilises the synergies developed in the .8 series power amplifiers. Unlike the INT-60, however, it brings 250 watts per channel of listening pleasure.
With higher power MOSFETs and more of them, the INT-250 drives large, demanding and relatively inefficient loudspeakers at higher volumes without batting an eyelash, singing beautifully. Just incredible music from one component.
The Bottom Line: Pass Labs’ integrated amplifiers are second to none.
Audiophiles, serious Audiophiles, have not considered an integrated amplifier as worthy product for 30+ years. Pass Labs has changed this paradigm, forever!
- Operational Points optimized for higher wattage requirements
- Greater Versatility
- Stable into any conceivable load
- Spectacular with difficult loads.
The new INT-250 builds on the point 8 series power supply and output stages. It uses the same efficient toroidal design in the power supply with both an electrostatic and Mu-metal shield along with vacuum impregnating and epoxy fill. This gives them a very quiet transformer both electrically and mechanically. The power supply circuitry itself is also lower noise and has additional filtering, a little more complicated but worth it.
The INT-250 uses a simplified preamp and volume control circuit that gives you sixty three 1 dB steps with lower noise and distortion while removing some signal path parts.
Overall, this creates a very good "one-box" option for many audiophiles and is capable of driving larger, less efficient loudspeakers.
