Hi,
Nope, sorry.
KMR are in Whetstone High Street (a few minutes walk from Totteridge & Whetstone Tube) and easy to find, a nearby Pizza Express outlet makes sure one can eat before/after auditioning (recommend before, food and beer/wine are not so good on ye olde hearing):

Niki @ KMR told me to just drop in when convenient, so I did. They where quite cool to let us play for ourselves, switch between monitors, fiddle with gear etc., it's a Pro outlett, so they really expect you to do "self service".
Ciao T
