The M30.1s sound quite different from the SHL5+. The M30.1s are capable of sounding big in a larger room fed with good power. Nevertheless, the SHL5+ will have a larger and more enveloping sound than the M30.1 apart from deeper and fuller bass.
The M30.1 has the small studio house sound which is great for vocals and small musical ensembles playing some jazz. However, it doesn’t sound as airy or open as the Compact 7ES3 and SHL5+ which are more of an all-rounder in my view. Personally I prefer the SHL5+ more than the M30.1 but that’s entirely based on my listening taste and personal preference. As always, it is best if you can listen and decide for yourself.
