I agree with @ghdprentice and the issue is electronics and value line speakers.
The Integrated you are using may be heater suited for use with a higher quality speaker. Has nothing to do with FS or SM speakers it is the quality of the components that make up that speaker, crossovers, tweeter type and materials, cabinets and mid bass woofer…..
For dual use HT and 2.1 listening look at GoldenEar BRX, ML Motion Series or further up the ELAC or Monitor lines. Get them from a retailer that has 60 Day Returns. Find what works in your home and be happy. Better yet go back to Dali..
