Yeah, it's some kind of satin finish, as Dan stated.
They (Wharfedale ) call it a "matte" finish over the wood veneer.
I used to own the 22L and while I don't own the Evo 30, I have spent quite some time listening to them.
The Quad 22L compared to the Wharfedale Evo 30, are a wee-bit cleaner ....sharper or in some systems more clinical. While the Evo 30 tends to retain a wee-bit more warmth and tunefullness.
The bass on the 22L can be boomy or wooly and it requires careful placement in the room. But placed rougly 24"-34" from the back wall and at least 18" off the sidewall, the bass can tighten up. It really depends on your room acoustics and the gear you have feeding it, upstream.
The Quad 22L image better than the Evo 30, but the Evo 30's midrange is much more sweeter and palpable. Again, to my ears.
The Evo 30's bass, to my ears, is tighter. But it too can be boomy under certain cicumstances.
Personally, I like the Evo 30, over the Quad 22L. But when buying, I went straight to the Wharfedale Opus 2, which I have had for over two years now and I love.
Wharfedale has discontinued the Evolution line and has repalced it with the Evolution2 (Evo2) series.
I haven't heard the Evo2 30, yet.
But in speaking with someone who has, I was told the Evo2 image better than the Evo 30 and it's whole frequency range is slightly cleaner than the Evo 30, while still retaining some of that sweet tone and tuneful midrange and palpability. He also said the bass was improved in then Evo2 30 with a new bass driver and some improvements in the driver alignment and internal cabinet structure.
Hope this helps.
