About our Phono Preamplfier

How can something so simple be so hard to do correctly? After all, the phono preampliers only job is to take the audio signal from the turntable and pass it to your stereo. But it turns out it isn't as easy as it looks. It may only have one job, but it turns out that job is pretty hard to do right. When playing a record, the turntable creates a complex but tiny audio signal which needs to be boosted before being sent to your stereo. This requires a very high quality, low noise power supply and circuitry in order to not damage the signal. To make things even more difficult, the audio signal from the record itself needs to be changed significantly to compensate for changes made during the recording process. Sounds tough? It is! As our service technician says, "it is amazing vinyl works in the first place". Analog Audio is well known for its expertise in analog products. We know the difference between a great sounding phono preamplifier and simple marketing hype. Although the finest phone pramplifiers are not inexpensive, price alone does not determine quality and performance. Whether this is your first turntable, or your crown jewel, we have the phono preamplifier and expertise to take your vinyl experience to the next level.
