PH1 Phono Pre-Amplifer


The Blackline PH1 is a high performance phono-pre-amplifier that supports both moving coil and moving magnet cartridges.  Although some amplifiers have an integral phono stage, PH1 is a dedicated phono pre-amplifier that offers an audible sound upgrade once connected between your Turntable and Amplifier.

Designed primarily to complement our range of Blackline valve amplifiers, PH1 can easily fit into any existing audio system where a phono stage is required.

Even if your existing amplifier has a built in phono stage, PH1 can be connected to Line In and will offer an improved performance as most built in phono stages are not of high quality.

The resurgence in vinyl and subsequently Turntables has prompted Blue Aura to develop a dedicated phono pre-amplifier.

An addition to our Blackline range, PH1 sits between your amplifier and Turntable and can be switched between moving coil and moving magnet cartridges.

Fundamentally, moving magnet cartridges have a higher level of amplification compared to moving coil type. The phono stage increases the signal level from the turntable cartridge to the amplifier and our dedicated PH1 phono stage will provide a sound improvement over traditional inbuilt phono pre-amplifiers.

A comprehensive review of PH1 can be found here.


PH1 was always intended to be introduced, but its customer demand that has accelerated its launch.

Customers who purchased our award winning v40 amplifier have been requesting a matching phono stage.

Now, after months of development we are ready to introduce a PH1 and we are confident consumers will hear a sound improvement when hooking up between an amplifier and turntable.
