Excellent customer service
Quick dispatch
Great quality components, very well packaged and worked exactly as planned. EVO caps have a nice fast sound with good snap but less warmth and smoothness as the evo oils.
My second hand Dali center sounded muffled, and ChatGPT correctly diagnosed the aged tweeter and specified this updated tweeter model. After a fast dispatch from Willys wifi (and paying the tax for EU), installation was easy. And now the second hand center finally sound as great as it should!
Good fitting niet look
I have just received and installed a pair of Monacor SPM-165/8 Midwoofers from Willy's HiFi.
The delivery came 24 hours from ordering the speakers online, the installation was super quick and easy, and they make a tired old pair of Mission 732's sound terrific!
This type of service, from a UK based company, gives me hope!
Thank you.
My 1st time using SB Acoustics drivers and I’m really happy with them. Very hi quality, looks to match and most importantly sound incredible!
