AlgoRhythm Picollo

Picollo Slider 2

The AlgoRhythm Picollo is a very compact analog headphone amplifier. It has a single input and output. Charging is micro USB 5v so you can charge from a computer or normal USB charger. The Picollo lasts a very long time on a single charge 24+ hours.

This is a unique and “old school” design at the same time. No op amps are used. Instead, we designed it using matched sets of triodes (total of 10 pairs) in a discrete component layout.

The Discrete Component Advantage

The design is unique in that it uses 10 pairs of triodes to perform the amplification, without the use of op amps. Very quiet background suitable for IEMs, but also very powerful for even large headphones. The improvement in audio, even from a headphone jack, is amazing.

The advantage of discrete component:
1. no unnecessary components with minimal interference
2. better quality components, more power
3. high resolution sound

The disadvantage of discrete component:
1. more space and more power-consuming
2. hard to design portable circuit
3. triodes must be precise matched: output triodes are hand selected
4. each amp must be hand-tuned, very time and labor consuming

Very large output spread supports ultra sensitive IEMs and large headphones:
low gain -12db, mid gain, high gain +11.5db
