New Amazing AVA Phono Preamplifier Options

We can now supply any new AVA preamplifier with two choices of new ultra big performance RIAA phono preamplifier choices.

The basic split passive EQ moving magnet phono section is $249 installed.  We can set this specifically for your phono cartridge upon request.

Newest, and the best yet is our new adjustable and flexible universal phono section.  Using a ten position gold contact dip switch per channel, this option can be easily user set for either moving magnet or moving coil use.  The moving coil gain is adjustable as is moving coil cartridge loading.  This is the best yet execution of our great new split passive EQ phono section.  The cost is $329 installed in any new AVA preamplifier.

These phono sections can also be retrofitted in most older AVA preamplifiers for an additional $50.

Please call us for details.  We guarantee satisfaction. 

New, the AVA ABX Comparator Switchbox

| Print |




The ABX Switch allows seamless switching of up to two preamplifiers, two power amplifiers, and three sets of speakers either with or without subwoofers.  

This allows you to make true, repeatable, and scientific double blind component comparisons.  Listen with your ears, not with your eyes!

The AVA ABX Switch can be used to evaluate cables and component parts as well as electronics and loudspeakers.  It can also be used for those that have more than one audio system for ease of switching.

Controlled by a universal remote, the ABX switch has the capability of:


  • Precise volume level matching, within 0.1 db, of any system.
  • Blind test modes (either informal or formal) force evaluations by how it sounds.
  • Works with or without a subwoofer.
  • Programmable power-up state and adjustable display brightness.
  • Persistent volume settings power up the same as they were when last powered down.
  • Multiple systems can be set up permanently and switched in/out with remote control.
  • low noise.
  • Built in "Y" splitter can be used to drive two units with one source.
  • Allows selection of up to two speakers at the same time. 
  • Mute entire system with a single button.
  • Gold plated RCA connectors for line level signal connections.
  • DC coupled (no capacitors in the signal path).
  • Ground lift capability should a ground loop noise problem exist (very rare).
  • $999


We suggest that the AVA ABX box is a necessary and very useful tool for audio clubs, component manufacturers, equipment reviewers, and just interested audiophiles.

Audio by Van Alstine offers you true state-of-the-art high-fidelity at prices you can afford. We have been designing and building truly musical systems for nearly forty-five years.

We sell direct so you can avoid high prices and high pressure. We avoid frivolous accessories. We want you for a long-term client, not for just a quick buck.

Our engineering staff is continually busy developing new designs and improving existing designs in our attempt to bring you the very best new audio equipment in every price range. In many cases we are able to offer affordable upgrades to your existing AVA equipment as well. Our upgrades to classic Dynaco and Hafler equipment are classics in themselves.

How good is our equipment? Our customers are our best sales people. Check the Audicircle.com, AudioREVIEW.com or AudioAsylum.com websites and search for "Alstine". You will see what our customers think.

Our clients get our ongoing expert consultation and guidance. If you call us we will take the time to listen and give you the best guidance we can. You get to talk to a real person, not an electronic switchboard.

Our equipment is custom built to your order in Minnesota by our skilled technicians who still remember what "high fidelity" means.

Do some background research

We love educated consumers! There's way too much fluff and magic in the audio industry - still freezing your CDs? For over 15 years we wrote a newsletter chok full of primers, essays, and the occasional tirade. For the first time, all of the Audio Basics issues are available online, free for the looking.
