EXPIRED For Sale Fosi Audio ZA3 Power Amplifier

Further Information

The 4 upgraded Opamps are worth $500 (and are new!) These as-new condition (literally 2 months old), new model ZA3 Stereo/Mono power amps, balanced by themselves are very good and very powerful. There are 2 so it's stereo.

But when you add 2 (new) Sparkos SS3602 opamps in the XLR stage, and 2 (new) Burson V7 Vivd Pros in the volume stage, and upgrade to the 48a5v power supplies, they become UNBELIEVABLY good!!! Watch Passion For Sound's video on them (link below).

They are rated at 180w into 4 ohm in stereo, but 48v 5w power increases that to 240w. These are insanely powerful, detailed, crisp with much imporved soundstage, (both width and depth) and and instrument separation, with the 4 upgraded opamps and power supply.

I use them to drive Elac Solano BS283 4 ohm bookies and a 300w Paradigm subby. The power, bass and clarity is amazing!!

I removed front plated to demonstrate some internals. More photos if anyone needs. Face plates come with them obviously (I like bright, flashy things haha, so left them off for the past few weeks).

The total amount is over $1000 ($500 for the 4 opamps alone), so this absolutely amazing value!!

I have added 8 lovely isolation feet and I also have done some cosmetic upgrades (LED's inside). Buyer can remove easily if not desired.

This is honestly a magnificent powerful and quality power amp package to get your speakers singing and the quality is so, so good (with the upgrades).

Can post for $20 anywhere in Australia, and welcome to demo, as it is with all of my items.

The new buyer will be extremely happy, just as I have been.
