Only 1 Music

It looks like Only 1 Music has closed down on City Road. The website subscription has lapsed, and the telephone number was given to someone else five months ago, and is now a residential number.
It used to be a retailer of musical instruments and sheet music as well as a recording studio of some merit, offering state of the art recording and production facilities that were aimed towards artists who wanted modern digital recording equipment and production capability.
Originally formed in 2000, the studio was first located in a suburb of Cardiff. By 2004 it outgrew the original premises and it was moved to the larger, more visible location on City Road.
They also used to carry a large collection of retro, vintage and contemporary instruments that was pretty impressive.
Can anyone please tell me what has happened to Only 1 Music as my attempts to finding out are drawing a blank?
Have they relocated to Penarth Road by any chance?
