Tagging classical is most of all a lot of work.
The internet databases in general recognize the CD but the results are often  a mess.

Don't be surprised if you get
Sonate für Klavier und Violine F-dur Opus 24 [Frühling]
Sonata No. 5 "Frühlings - Sonate"
The Violin Sonata No. 5 in F major “Spring”, Opus 24

Often the composer is stored in the artist field and the performer hopefully in the album title.

What you need is tags for Composer and Composition and have them populated in a uniform way.

The MusiCHI tagger addresses these problems.
It has pick list for Composer and Composition.

You can also batch process your collection (MusiCHI Clean)

The text processor offers a lot of options to cleanup your tags.

I do recommend the MusiCHI Tagger.
It is a real time saver when tagging classical.

Genelect G-series

Genelec is well known in the pro-world.
In 2013 they launched the G series targeting the home.
I do think active speakers for home use is becoming a new trend.
