In any case, the difference between 180W and 200W is completely inaudible, less then half a decibel.

Consider this as a 125W to 175W rated amplifier, and it way outperforms those ratings. Since I had paid for a "200 WPC" amp, I sent it back. As a family man today, I no longer have time to try to fix or analyze problems with items I've bought - I simply returned it to the fantastic dealer from whom I purchased it.įor all I know, the actual output power of this sample is perfectly normal for the USA model - just that no one had the equipment to measure this back in 1986. I purchased this unit personally, but when I discovered slightly low power output and something potentially fishy in the protection circuits (I have no idea if the circuits were defective just designed this way since day one (scroll down for green text)), I returned it, so my time with this sample was limited. I suspect this Sony I bought was defective to some extent either as a sample or in design it has a screwy self-protection circuit in addition to its speaker protection circuitry which kept clicking a relay, and I suspect kept switching supply-rail voltages as I tried to test it. While both this Sony the ADCOM GFA-555 II are rated at the same 200 watts per channel into 8Ω, the ADCOM easily puts 260 W continuous and 370 W on tone bursts into 8Ω, while this Sony only puts out 180W maximum into 8Ω, period. The big gotcha with this huge 55-pound Sony is that, in Japanese tradition, it only barely meets its claimed power output. It draws so much inrush current that it usually tripped my UPS when turned-on it dropped the line voltage enough that my UPS kicked-in to correct the dip.

There are no fans, and its power transformer makes no buzzing. This Sony has the advantage of silent running. This Sony amp sounds great, and its high-frequency THD measures better in the lab than any other amp I've had in even better than the newer 200 WPC ADCOM GFA-555 II. Such is niche marketing, but remember, I can't tell you any of this. Accuphase reduced the P-4100's output power for economic reasons to only 90 WPC, and of course raised the price by ten times over what Sony asked for this landmark TA-N77ES.

The Accuphase P-4100 uses the same isolated power supply for the drivers ("Spontaneous Twin Drive"), the same triple-parallel bipolar output stage, the same idle-power draw, and even the same speaker, meter, input and attenuator controls - and of course the same wonderful huge meters. No one will admit to this and I can't tell you it either, but Sony cleverly sold the design to Accuphase in 1989, who still sells it today in their model P-4100. This N77ES was Sony's biggest and best of all time Japan's last stand before before audio was left to the weirdos and everyone normal preferred to watch their VCR on the big screen. The TA-N77ES was Sony's last effort at pushing the envelope of serious power amplifiers at the end of Hi-Fi's glory days.Īs VCRs and big-screen TVs forever replaced music as people's primary form of recorded entertainment in the mid 1980s, Sony's next amplifier, the TA-N80ES, was the same thing without the meters, and Sony's next amplifier after that was the TA-N90ES, which was a half-power version of the meterless TA-N80ES. It's a 55-pound behemoth with huge meters that sounds and measures extremely well. The Sony TA-N77ES is Japan's greatest power amplifier of all time.

I use Adorama, Amazon, eBay, Ritz, B&H, Calumet, J&R and ScanCafe. (Note: my photos here have been cleaned-up and are not in any way part of the listing.) Buy it and you'll get the only Sony amp for sale today that's been through a battery of serious laboratory certification! These are nearly impossible to find at any price, especially with meter lights that actually work, because they were so insanely expensive when new that few people could afford to buy them.
