My "Summer System"......We have a small, three season, sunroom. We spend most every night out there during spring , summer and fall. I wanted music out there, but I didn't want to simply install extension speakers off the main system. So decided on a VERY inexpensive "Summer System".......12 X 12 X 10 cathedral ceiling. Three walls of glass! I chose the Topping MX3 amplifier with USB, Bluetooth and AUX input ($140). The only source we currently listen to is Qobuz and Amazon HD, so an Andover Songbird did this duty ($129).....Speakers are JAMO S803 ($149)......Finally got it all hooked up today. I wish you could hear it. It is simply amazing for the meager investment. The bass from these little speakers is tight, and deep enough to satisfy the most ardent jazz and rock fan. The topping has bass and treble controls, in this glass cube a bit or treble attenuation was needed. Totally listenable! I'm amazed at how far inexpensive stereo equipment has come.
