Sony took their hi-fi product lines very seriously back in the day and this TA-FA777ES amplifier is a testament to it. Let’s take a look inside.
The Sony TA-FA777ES is part of Sony’s ES product range from the 1990s. Tragically and as Sony fans around the world lament, this was the last of the really serious stuff from Sony. They knew it and, as a send-off, boy did they built them well!
The TA-FA777ES features premium parts throughout including my favourite Nichicon Fine Gold capacitors, literally as far as the eye can see. The chassis is copper plated, uses copper-plated screws and the heatsinks and toroidal transformer are things of beauty.
The TA-FA777ES contains an excellent phono preamplifier, uses premium HEAVY knobs and features superb overall build quality and aesthetic appeal, in keeping with its several thousand dollar price tag in 1999.

With the lid off, you can see the Sony TA-FA777ES is a serious unit. Big filter capacitors mean lots of stored energy, great for dynamics.
OK, enough golden puns, time for service. In this case, I cleaned and lubricated switches and controls and adjusted bias current to the output devices. I also cleaned the entire unit, treated the connectors and so on.
Comparing New and Gold…
It’s always very satisfying to listen to an amplifier like the Sony TA-FA777ES after servicing it. Only during final testing do I get to hear the combined results of my work. The silent controls, the added warmth, punch and smoothness in this case. Definitely worth it.
Before you ask about new amplifiers and the latest technology, let me save you some time. There is no new technology in amplifiers that improves sonic performance. Sony doesn’t even make high-end amplifiers any more. Denon, Luxman, Marantz and Yamaha do, and you pay dearly for modern amplifiers like this, so let’s look at some current ‘equivalents’.
The Yamaha AS-3000 is a lovely amplifier, priced at $8,999 AUD and featuring similar build and power. The AS-2100 is not as good but costs less @ $3,999. Luxman makes the gorgeous L-507uXII, a snip at just $8,499, or the L-505uXII @ $6,499. The pretty Marantz PM11S3 is definitely not as well-built as the Sony yet costs $8,600 AUD. Perhaps the closest in spirit is the Denon PMA2500NE, priced at $5,199. It contains a DAC and is nearly as well put together. Yes, I said nearly. Which of these would I have? The Sony or the Yamaha AS-3000.
Hopefully, you see the problem. There’s sort of similar stuff out there, but not really, and it’s scary-expensive. Needless to say, the Sony’s owner, a lovely gentleman who works for one of the last real hi-fi stores in Perth, is very happy with his amplifier and doesn’t want or need to take out a second mortgage for a replacement. He’s not parting with this beauty any time soon!
