ALO Audio Continental V5 Portable Tube Headphone Amplifier

ALO Audio

Our newest generation of the Continental line is out best yet.

We took the most exciting elements of our favorite amp designs and combined them into a single portable high-fidelity personal amplifier.

  •  Hybrid Design

    CV5 is a “Vacuum Tube / Solid State Hybrid” Amplifier. It delivers low impedance, tight bass control and sonic detail you expect from amplifier (RX) with the added spatial qualities and sonic lushness you’d expect from a vacuum tube based amplifier (CDM)

    The 6111 vacuum tube is picked at the input stage of the CV5 running in Class A. Since the 6111 is a dual triode, left and right channels share the same vacuum tube without issue. The CV5 is Class A tube input and Class AB Solid State Output.

  • Single Tube

    At the center of the CV5 is a single New-Old Stock (NOS) 6111 Vacuum Tube.

    Each of these tubes is individually soldered to a custom printed circuit board.

    This provides mechanical isolation of each tube from unwanted microphonics.

    It also provides a quick and easy solution to tube-rolling.

    This is a tube solution was first deployed in the Continental Dual Mono and now we’ve introduced it to the CV5.

    Dynamics

    Hugh Sonic Dynamics Result from the borrowed power supply design from the new RX.

    The CV5 goes one better with a 16V power supply, with +/- 8 Volt Swing.

    This allows plenty of Headroom for loud and/or complex passages.

    They are reproduced in a way that sound wide-open and distortion free.

    Machined Enclosure

    The CV5 enclosure is machined from a single block of aluminium. The markings are machined into the enclosure so that wear is not a concern during the life of the amplifier.

    Machined ventilation holes allow the tube to breathe easily and keeps the unit cool during normal operation.

    Each amplifier is hand assembled and tested in our Portland, Oregon workshop. Each unit is carefully inspected to assure you years of satisfied and reliable product ownership.
