I recently got JBL stage A180 speakers (have auditioned them on couple occasions and chose A180 instead A190 - much more focused, clear bass and mids).
Since i couldnt wait for amplifier, i took "first in hand" - Yamaha R-N402D stereo receiver.
These are R-N402D specifications:
Minimum RMS output power (40 Hz to 20 kHZ, 0.2% THD, 8ohm) 100 W + 100W
Dynamic power per channel (IHF) (8/6/4/2 ohm) 125/150/165/180 W
Maximum powr per channel (1 Khz, 0.7%THD, 4 Ohm) 115 W
IEC power (1 Khz, 0.2% THD, 8 Ohm) 110 W
Damping factor (Speakers A) 1KHz 8 Ohm, 120 or more
Maximum effective output power (1 Khz, 10% THD, 8Ohm) 140 W
Total harmonic distortion CD, etc. to Speakers out (20 Hz to 20 kHz, 50W 8Ohm) 0.2% or less
Signal to noise ratio (IHF-A), CD, etc. (input shorted, 500mV) 100 dB or more
As stated in Yamaha manual - speaker impedance RN-402 is 8 Ohm or higher. If you connect speakers with an excessively low impedance, this unit may overheat.
JBL Stage A180 are 6 Ohm impedance. Due to lower impedance of JBL A180 (6 Ohm), will there be any damage to speakers or receiver (8 Ohm)?
Another thing which is "annoying": there is a slight hiss noise coming from speaker tweeters (while nothing is playing and volume set to minimum).
When i change the input source to CD - hiss is audible. When switched to Optical / Coax - the hiss is gone, theres just a slight high pitched noise). Is this hiss produced by low quality of Yamaha amp? Anyone with similar experience?
Final question: which receiver/amplifier can be recommended for JBL Stage A180 (that doesnt produce hiss or noise)?
I was thinking Yamaha R-N803 (reviewed here with passmark), or perhaps Denon DRA 800H, Topping PA5 with decent DAC (if Topping has enough power for JBL Stage A180)?
Thank you.
