Hey guys, I’ve bought my first proper setup and finished setting it up yesterday. I’m new to the audiophile world, so I’d appreciate your opinion.
**Setup:**
Speakers: Two KEF Reference Model 2s (old, but still capable)
Amp: Yamaha AX-750
Streaming: Apple AirPort Express
I’m quite happy with the sound overall, but I feel like the volume could be higher, especially when playing music from Spotify. I usually listen to Techno and dub on SoundCloud, and some tracks sound amazing and can’t go higher than 60% as the walls are already shaking. But when I listen to other genres on Spotify, I sometimes have to nearly double the volume to get the same listening level.
For some tracks, I have to turn the amp up to around 80%, and even then it’s not particularly loud. At 80%, I’d say it’s just at a comfortable level for normal listening.
Is this normal, or could there be something wrong with my setup? Could it simply be that some recordings are mastered at a much lower level?
Also, is there a good way to test whether the highs and mids are working properly?
One thing to mention: the input selector has an issue. Sometimes it creates noise or one speaker cuts out, but it goes away when I touch/move the knob. Could this issue somehow affect the output power of the amp, or is it unrelated?
