We are pleased to say that the TOPPING Pre90 Preamplifier and the Ext90 Input Extender are now available for purchase on Apos Audio!

The Pre90 is a preamplifier that uses the same NFCA structure as the TOPPING A90 amp, allowing higher gain and slew rates but with lower distortion. It is fully balanced and can accommodate both balanced and single-ended signals (output can be balanced, single, or balanced and single). The Ext90 is an input extender that allows you to connect up to a whopping six more additional inputs to the A90/D90 stack.

The Pre90 also has some helpful features for us audiophiles who have lots of sources. There is an easily accessible Volume Memory Function, allowing you a user-friendly experience as you switch between different input sources, since different hardware has different outputs. Not only that, but TOPPING has included a “Safe Volume Function” in the Pre90. Have you ever had one of those evenings when you settle onto the couch, turn your speaker system on, switch inputs, and then the system blasts out music, causing you to frantically reach for the volume control as you think to yourself, “Why didn’t I double check that?” Now you can let your future ears rest easy, because the Safe Volume Function kicks in if the volume is turned higher than the set safety level, causing the sound to be muted first and prompting you to override the setting manually or to confirm you want louder music.

Please check out the product page to learn more about the Pre90 and Ext90. If you have any further questions or need more information, you can begin a live chat with our dedicated Support Team or you may email us at “support@apos.audio” and we’ll reply asap!
