Welcome letshearit ...
Dyns are an excellent choice for an all-arounder. Location and treating the dedicated space to them is a great start. IF you are on a learning curve, building around a beloved speaker choice, integrated amplification is a fine approach. If digital source only, tubes somewhere is a must for me. I ran similar sized, power hungry Salk Veracity loudspeakers for several years in my small, dedicated space, successfully.
Upgrading (yes) to a smaller Revolution Be (more detail in my posts) loudspeaker and adding a Rythmik L12 sealed subwoofer while rolling off my Music Reference tube amplifier at 80Hz to the monitors provides tons of dynamics and musicality. The EL84 tube 4some provide whopping thunder to the Be's, while retaining delicacy. letshearit, I suspect adding a similar subwoofer approach to the Dynaudios would yield a similar result.
Bon Chance and welcome to the worlds of even-order harmonics! Find someone nearby with whom you are comfortable as an Advisor, then trust your ears and judgement. It's a fun ride.
