    Would this be worth picking up for a 2 channel amp?  The picture looks good.  The seller says "good working order".  How much would it be worth?

    From The Vintage Knob...

    Sony TA-F555ES
    Sony TA-F555ESII
    (1983 - 1985 - 1987)

    The TA-F777ES topper, like a few other early ES units, was not released outside its country of origin so, elsewhere (everywhere), the F555ES represented the top of the newly (re)launched ES series. A fairly basic amp if very healthy indeed, and quite a best-seller, too. But the ES line was starting afresh so the PPS, Heat-Pipe and other "old" technologies had vanished... The one reminiscence is the placement of the volume knob: left, just like the pre-Esprit and ESPRIT preamps, thus hinting that these amps also used the "simple signal path" inaugurated with the TA-E88B in 1976 - but hinting only.

    The F555ES was largely upgraded in mid 1985 (F555ESII), gaining power, weight and a fully copper plated chassis, replacing along the way the AUX input with two a/v inputs plus a loop/monitor and scrapping the pF settings for MM carts (sign'o'the times).

    Mostly, inside, the F555ESII was a smaller... TA-F777ES ! This revised version garnered a Stereo Sound "Best Product" award, following in that -surprise- the original F777ES !

    Thank you for  quick reply.  The Vintage Knob info you linked is about all that is available on the web.

    I did get it, for $90 cdn.  It is in excellent condition & sounds good.  Two LEDs above the selector buttons don't work, I will take it apart to find the problem.

    What speakers will you be using your new Sony TA-F555ES with?

    I will be using it with Klipsch RF82

    The indicator lights above the selector buttons were 12 ohm flourescent lamps.  I replaced all of them with LEDs and 270 ohm series resistors.

    The widened prong for polarity protection on the power cord was filed down.  I replaced the power cord with a hospital grade power cord.  I also internally cable tied the AC wires for the power switch and transformer, holding them farther away from the wires that go to the internal speaker terminal connections.

    This unit has previously had some internal components replaced.  It has solders that are not factory original.


    How does it sound?  I am impressed.  I haven't done an A/B comparison to the DA4ES or DA3100ES, but I think it sounds better.  This unit has good detail and separation, I can hear subtle sounds that I don't think I can hear on my ES receivers.   I will have to get a speaker switch to perform some A/B tests.

    I took the TA555ES to an audiophile friend yesterday evening for his opinion.  He was impressed and had a big smile on his face.  We turned the volume up to about 70% while we were listening to it.  That is "much" louder than I would ever dare to turn it up to at my place.  At 70% it is very clean sounding, nice detail & no audible distortion.

    Yeah, 90 bucks well spent.  It was worth it.

    The improved sound quality that you describe the TA 555ES Integrated Amp having are similar with what I have heard separate Preamp/Power Amp combinations have over my Sony Receiver. When you say some of the soldering is not factory original were the parts that were replaced of a superior quality?

    They are similar quality to the original, probably to replace aged components.  I might do some parts swapping/upgrading in the rainy weather fall & winter.

    I'm sure that you are aware that most hard core Audiophiles recommend Electrolytic Cap replacements for vintage Audio gear due to their limited lifespan. One owner completely retrofitted both of his TA N9000ES Power Amps with Black Gate Electrolytic Caps and he said that it made a night and day improvement in both sound quality and performance.

    I will be seeking input here & locally when it comes to replacing parts in the TA-F555ES.

    Richard Kern of Audiomod is one of the most widely respected Sony Modmen in America and he once gave me a 30 minute explanation of why the secret to his success was the exclusive use of carefully matched Black Gate Capacitors. Sadly Richard closed his business late last year, but if you put his name into the Audio Asylum search engine it will max out the allowable number of results and you will see nothing but praise for his amazing work in upgrading Sony Audio equipment to the most demanding Audiophile Standards.

    Maxx - thank you for your input.  It has been a fair while since I posted anything here.

    I have done quite a bit of work in the TA-F555ES since my last post.  I have replaced a bunch of the internal wiring with 12 gauge wiring, this includes all the wires to the internal side of the speaker terminals.  I have also replaced over 30 of the capacitors, using Nichicon FG & KZ caps.

    I have not finished working on the F555ES so I do not have an "after" picture yet, but here is the "before" picture.

    Its great to hear from you again! Your Sony Integrated Amp is going to be so much improved that you are going to have to give it a new and upgraded model designation... ie TAF999ES!!!

    Nice amp and now even better!
    I wish I was handy with that kind of stuff.I can build computers starting from one screw but soldering and electicity I have not studied much.
    Knowing my personality I'd be upgrading parts like crazy in my system lol!

    Good job!

    Building computers from scratch is an admirable skill.  Incompatible parts and software can bring a person a lot of grief.
