Have you adjusted the Source Level under the Line-In settings under System in the Sonos app? Also make sure the Audio Compression setting is set to Uncompressed.
In addition to what @GuitarSuperstar suggested… know this:
Keeping things simple…Using acmore powerful Amp will not make the speakers play louder. There is always a point wherein the speaker will clip when the driver’s limit is reached or exceeded.
For example an Amp with 100 Watts RMS vs one with 50 Watts RMS in simplicity means that the speakers maximum volume limit may be reached at the 10 O’clock position vs the 12 O’clock position with the less powerful Amp.
Hi Rashi
Cheers have done that and it has made a difference.
Hi AjTrek1
The reason I ask is that the speakers were hooked up to a Technics hifi for years (80’s. Vintage) which was about 60 watts. The volume was far far higher than it is from the connect amp. So the speakers are well capable of handling high volume.
Is there anything I can do to improve this.
