Yamaha R-N301 sounds... wrong after moving and plugging into other speakers
I'm sorry if it's rude to ask for technical help here, particularly given I have had 0 engagement with this forum in the past. But I'm stuck. I'm lost. I don't know if anybody can help.
I recently moved house, and bought some Q-Acoustics 3050i to go downstairs. I already have a Yamaha R-N301 paired with Wharfedaler Onyx 300s, which lives on my desk.
To test out the 3050is, I plugged them into the Yamaha - which drove them way better than I expected, and they sounded great. Then, I returned my Yamaha to the Wharfedales, and it sounds wrong. It's lost lots of the treble and bass, and gotten boomy in the mid-end. I've checked the phase of the speakers, I've checked the other speaker channel, I've verified the EQ is flat like I've always had it, I've verified that there's no difference between the DAC via Optical, the DAC via Network, or the Analogue (from a Phono Pre-Amp and turntable). I can't see any voltage or current physical switches that I've moved.
I'm stumped. it just sounds wrong, and it's breaking me up a little. I legitimately struggle to listen to music with it, because I know what it sounded like before, and it's just... wrong.
I'm trying to avoid the 60AUD quote fee + fix cost + weeks without an amp even if they can't do it - because, what if they don't find anything? What if they come back with that the sound is subjective or something?
I'm not sure where else I can ask. Help? Please? I'd rather not replace it just yet - it's barely out of warranty, and moving and getting married was expensive!
