Product Description

Audio Alchemy Phono Stage PPA-1. Outstanding performance. Ultra Quiet. Made in U.S.A.

Now at True Audiophile

The world is filled with phono stages. Many promise. Few deliver. Audio Alchemy followed up on their other products with the same rabid audio intensity to develop a phono stage that - well as one audiophile in Japan claims "nothing under $20,000 can touch it. -- TA

Overall, the PPA-1/PS-5 produced an impressively well-balanced rendering of what had become a very familiar album. I could point out the differences between the PPA-1/PS-5 and the very expensive phono preamp but that would just be a waste of our time....PPA-1 is a high performance, feature-rich, versatile, well-built in America, MM/MC phono preamp that is among a handful of the best under $2000 phono preamplifiers available today...Michael Fremer

Ultra-Quiet Phono Stage

The PPA-1 uses all-analog, discrete FET gain and EQ stages to transform the microscopic grooves in vinyl records into stunningly lifelike music. It includes all the features that serious vinyl enthusiasts demand, such as continuously variable input loading, MC/MM gain switching and XLR and RCA outputs. It can also be upgraded by adding the PS-5 power supply, which can simultaneously power the PPA-1 and one other Audio Alchemy component, such as the DDP-1digital preamp.

Magical Analog Musicality

Analog signals from vinyl records are already perfect when they leave the phono cartridge; all they need is to be handled correctly and with the least amount of processing in their path to the preamp.  That's why Audio Alchemy uses all-discrete, ultra-low-noise FET circuits for the PPA-1's RIAA EQ and gain stages, with no integrated circuits in the signal path.  It's also why Audio Alchemy provides an easy upgrade path: Just replace the supplied power supply with the PS-5, which offers superior filtration, tighter voltage regulation, lower noise and greater energy storage.

Transforms to Suit Any System

If you are a serious vinyl enthusiasts you need more than just the basic options. That's why Audio Alchemy gives you what you need. Load impedance is independently, continuously adjustable for both inputs, so optimal performance can be achieved with any cartridge and you're not locked into specific settings. Either input can be set for MC or MM gain, and balanced XLR outputs are provided in addition to single-ended RCA outputs.

PPA-1 Features:

  • Fully discrete, all-analog FET design with no ICs in signal path
  • Selectable MM or MC gain
  • Two single-ended RCA inputs with continuously adjustable loading
  • Balanced XLR and single-ended RCA outputs
  • Upgradeable through addition of PS-5 external power supply
