Grado RA1
The RA-1 was designed specifically to drive Grado headphones and it does that quite decently. It's recommended for use with fairly efficient (low impedance) headphones like the 32-ohm Grado Labs headphone line.
Product Features:
- Signature Grado wood enclosure
- Full size 1/4" headphone jack
- Battery powered for portable use
The RA-1 was designed specifically to drive Grado headphones and it does that quite decently. It's recommended for use with fairly efficient (low impedance) headphones like the 32-ohm Grado Labs headphone line. This is the battery-powered amp unit. The 'AC-power' Grado RA-1 model has been discontinued by Grado Labs.
The RA-1 is small and fairly light for portable use, although that trad Grado wood-block design makes it somewhat bulky for easy travel and mobile listening on the fly. It's a very simple yet effective amp; the front panel sports a volume control, an on/off LED light, and a full-size 1/4" headphone jack. The rear of the amp provides an on/off switch and one pair of left/right RCA inputs. The battery compartment holds two 9V batteries, and is easily accessible via a metal plate with two screws located on the bottom of the amp. One bummer: the battery-powered RA-1 does not operate with a wall wart/AC adapter.
