Sony TA-F 690 ES

I have to commend Mr. Janečka; I sent him a Sony F690 ES for a minor repair, and ten days later, the amplifier arrived back in a “new outfit.”

I was pleasantly surprised after turning the amplifier on.

The sound was more spacious and cleaner, with lower frequencies that were softer and more pleasing to the ear.

I can say that the sound is a class above.

I highly recommend him…
