I owned this receiver for approximately a year before selling it. In that time I never encountered any noise from the transformer, or any other electrical noise / interference.The R-S202 is a perfect fit for my application. I have questions for owners:
1. Zero Fidelity's review on YT reported mechanical 'hum' from the transformer, has anyone here had this problem?
2. How is FM tuner performance (sensitivity, noise, audio quality) in comparison with other tuners you may have tried?
3. How is the Bluetooth audio quality (with high bit rate MP3) in comparison with other Bluetooth receivers you may have tried?
Thanks in advance!
The FM tuner performance was surprisingly good in regards to sensitivity and noise. The FM audio quality was at least as good, or better, as the tuner in any modern receiver I've heard, but that's not to say it was great. Compared to a good quality component tuner (my comparisons included Yamaha's T-80 & TX-950, and NAD's 4300) it falls well short. But the only component tuner currently produced that I'm aware of (NAD's C 427) is more than double the price of the R-S202, so the price/performance ratio of the Yamaha is very good.
As for Bluetooth, I only used it occasionally and briefly, but I can say that functionally it was easy to use and no problems arose. In regards to what another poster stated, there was no BT antenna installation on my unit. I assumed the antenna is internal. BT pairing could only be done via the remote. The model I owned was the R-S202 which I believe has been changed to R-S202BL, but I believe the two model numbers are for the exact same receiver.
As for the spring connections for the speakers, yes they're horrible in every way. I forget what gauge wire they accepted, but I do distinctly remember having to search my home for the thinnest speaker wire I could find. Perhaps it was just my unit, but it appeared that no matter how much or little I depressed the spring terminal it never produced an unobstructed opening to insert the wire, so even the thinnest gauge wire was difficult to insert. Truly awful.
